  • Safari openwindow function behavior on iPad versus iPhone

    - by CodeLizard
    An identical javascript:openwindow call with a link to Google maps opens in Safari on the iPad but in the Google Maps App on the iPhone.

  • How do I get the inserted id (or object) after an insert with the FormView/ObjectDataSource controls

    - by drs9222
    I have a series of classes that loosely fit the following pattern: public class CustomerInfo { public int Id {get; set;} public string Name {get; set;} } public class CustomerTable { public bool Insert(CustomerInfo info) { /*...*/ } public bool Update(CustomerInfo info) { /*...*/ } public CustomerInfo Get(int id) { /*...*/ } /*...*/ } After a successful insert the Insert method will set the Id property of the CustomerInfo object that was passed in. I've used these classes in several places and would prefer to altering them. Now I'm experimenting with writing an ASP.NET page for inserting and updating the records. I'm currently using the ObjectDataSource and FormView controls: <asp:ObjectDataSource TypeName="CustomerTable" DataObjectTypeName="CustomerInfo" InsertMethod="Insert" UpdateMethod="Update" SelectMethod="Get" /> I can successfully Insert and Update records. I would like to switch the FormView's mode from Insert to Edit after a successful insert. My first attempt was to switch the mode in the ItemInserted event. This of course did not work. I was using a QueryStringParameter for the id which of course wan't set when inserting. So, I switched to manually populating the InputParameters during the ObjectDataSource's Selecting event. The problem with this is I need to know the id of the newly inserted record which I can't find a good way to get. I understand that I can access the Insert method's return value, and out parameters in the ItemInserted event of course my method doesn't return the id using any of these methods. I can't find anyway to access the id or the CustomerInfo object that was inserted after the insert completes. The best I've been able to do is to save the CustomerInfo object in the ObjectDataSource's Inserting event. This feels like an odd way to do this. I figure that there must be a better way to do this and I'll kick myself when I see it. Any ideas?

  • Scrollbar with Sprite and Rectangle won't move text, just the Rectangle it's painted on.

    - by WebDevHobo
    Warning: school assignment. For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you. So I needed to get a Scrollbar, which I got here: http://kirupa.com/forum/showthread.php?t=245468 (all files in a zip linked at the end of this text) The thing is, it works with Sprites. After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have. So I tried adding the TextFieldExtended instance to a Sprite instance using addchild. A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it. My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible? If so, any scrollbars you can recommend, because it's too extended for me at this point. All files: http://www.mediafire.com/?q2ium22gmox This was made in Flash CS4 using ActionScript3. The Example class is the final implementation

  • Custom UIView using CALayers disappears after 180º rotation or navigation controller pop

    - by Steve Madsen
    I have a created a custom UIView subclass that is exhibiting some strange behavior. It is a spinning wheel selector, and for performance reasons it is drawn entirely into two CALayer instances. The bottom layer is the wheel itself, which is rotated using setAffineTransform: according to touches. The top layer is eye candy. drawRect: is fairly simple. If the control hasn't been drawn yet (or it's been invalidated), it calls a method that creates the images and assigns them to the layer contents property. - (void) drawRect:(CGRect)rect { if (imageLayer == nil) { [self drawIntoImageLayer]; } [self updateWheelRotation]; } When the view controller using this view first appears, everything is fine. There are two instances where the view completely disappears, however: If the device is rotated a full 180°. After a view controller is popped off the navigation stack and the view becomes visible again. drawRect: is not called either time. Interestingly enough, it IS called after a 90° orientation change, and that causes the view to re-appear. How can I ensure that a custom view using CALayers is redrawn properly in these situations?

  • .Net Architecture challenge: The Change-prone Frankestein Model

    - by SDReyes
    Good Morning SO! We've been scratching our heads with with this interesting scenario at the office, and we're anxious to hear your ideas and approaches: We have a database, whose schema is prone to changes -lets call it Prony-. (is used to store configuration parameters for embedded devices. so if the embedded devices guy need a new table, property or relationship for the model, he should be able to adapt the schema in a easy way -happens so often- ). Prony needs a web interface to create/edit its data. We have another database containing data that also need to be loaded to the devices, after making some transformations - lets call this one Oddy- (this data it's generated by an already existent administrative web application). Finally we have Tracy, a server that communicates our DBs and our embedded devices. She should to auto-adapt herself, to our dbs schema changes and serialize the data to the devices. Nice puzzle, don't think so? : ) Our current candidates: Rady: The fast Lets create some views in Prony that make the data transformation from Oddy. then use DynamicData (or some RAD tool) to create/update a simple web interface for Prony (so he can even consult the transformated data from coming from Prony : ). About Tracy, she will need to be recompiled to update her DB schema (Entity framework should work) and use Reflection to explore recursively the schema and serialize data. Cons: We would have to recompile Tracy and the Prony's web interface. What do you think of the candidate(s)? What would you do?

  • passing callback function accross windows causing error with ie ...

    - by krul
    I have a problem with IE causing two errors: 1. Object doesn't support this property or method 2. Call was rejected by callee. My Intention: To call window.opener.myObject method that is going to retrieve some data using ajax and pass in callback function that live as nested function in popup window that initiated call that is going to handle response data and modify popup window html accordingly. Here is a scenario: I pull up popup window that handles some specific operation. This popup window calling window.opener.myObject method that using ajax call. I'm passing in popup window function that is going to handle response and it works with ff and safari but not with ie. Here is code sample //RELEVANT SCRIPT ON POPUP WINDOW $('#myButton').live('click', function() { var h = window.opener.myObject, p = { 'p1': 1 }; var responseHandler = function(responseObj) { //in IE we never got here if (!responseObj) { alert('Unexpected error!! No response from server'); return false; } //..handle response }; p.p1 = $('#control').val(); h.executeMethod(p, responseHandler); }); //RELEVANT SCRIPT ON WINDOW OPENER MYOBJECT try { $.ajax({ type: 'POST', async: true, url: url, data: postData, dataType: "json", contentType: 'application/x-www-form-urlencoded; charset=utf-8', success: r, // r here is reference to my responseHandler popup window function error: handleError }); } catch (ex) { alert(ex.message); } Any tips?

  • Flash "visible" issue

    - by justkevin
    I'm writing a tool in Flex that lets me design composite sprites using layered bitmaps and then "bake" them into a low overhead single bitmapData. I've discovered a strange behavior I can't explain: toggling the "visible" property of my layers works twice for each layer (i.e., I can turn it off, then on again) and then never again for that layer-- the layer stays visible from that point on. If I override "set visible" on the layer as such: override public function set visible(value:Boolean):void { if(value == false) this.alpha = 0; else {this.alpha = 1;} } The problem goes away and I can toggle "visibility" as much as I want. Any ideas what might be causing this? Edit: Here is the code that makes the call: private function onVisibleChange():void { _layer.visible = layerVisible.selected; changed(); } The changed() method "bakes" the bitmap: public function getBaked():BitmapData { var w:int = _composite.width + (_atmosphereOuterBlur * 2); var h:int = _composite.height + (_atmosphereOuterBlur * 2); var bmpData:BitmapData = new BitmapData(w,h,true,0x00000000); var matrix:Matrix = new Matrix(); var bounds:Rectangle = this.getBounds(this); matrix.translate(w/2,h/2); bmpData.draw(this,matrix,null,null,new Rectangle(0,0,w,h),true); return bmpData; } Incidentally, while the layer is still visible, using the Flex debugger I can verify that the layer's visible value is "false".

  • Convert Form to UserControl

    - by Joe
    I have a 3rd party code library that I'm using; part of this library is a winforms application for editing the configuration files used by this library. I would like to embed their configuration editor app into my application. I have the source code to their library and the configuration editor is (as far as I can tell) a straight forward Winforms app using standard controls. I'm trying to convert the app's main form into a UserControl so that I can host it inside my application which is WPF (WPF's WindowsFormsHost won't host a Form object, I get an exception). I changed the form object to inherit from UserControl instead of Form and fixed all the compiler errors (there weren't many, just property initializations that don't exist on UserControls) but what's happening is my newly converted control is just blank. When I run my test app I don't see any of the controls that make up the original form, just a blank page. Any ideas? I really don't want to have to re-implement their app from scratch, that would suck. Edit: I forgot to mention I'm testing this in a WinForms application, not WPF, to just get the control working before trying to use it from WPF.

  • Asp.Net tree view in SharePoint webpart- Input string error

    - by Faiz
    Hi All, I am facing a very strange issue. I have a SharePoint webpart that displays an asp.net tree view. It takes tree depth from a drop down. To improve performance of the tree view, i am setting the PopulateOnDemand property to true for the last level of the tree depth. For example, if i have a total of 10 levels in the data and the user selects tree depth as 3, then the third level data i set PopulateOnDemand to true. Now comes the strange part. When i click on the + image on the third level, and if there are children under that particular node then call back happens and node gets expanded. But if there no children for that particular node, then click + throws "Input string was not in the correct format" error. I have made sure that there is no server side error. Some things looks to be fishy when internet explorer is trying to bind construct the expanded node. Please let me know if any one faced similar issue or the resolution for the same? Thanks in advance

  • Will the following NHibernate interface mapping work?

    - by Ben Aston
    I'd like to program against interfaces when working with NHibernate due to type dependency issues within the solution I am working with. SO questions such as this indicate it is possible. I have an ILocation interface and a concrete Location type. Will the following work? HBM mapping: <class name="ILocation" abstract="true" table="ILocation"> <id name="Id" type="System.Guid" unsaved-value="00000000-0000-0000-0000-000000000000"> <column name="LocationId" /> <generator class="guid" /> </id> <union-subclass table="Location" name="Location"> <property name="Name" type="System.String"/> </union-subclass> </class> Detached criteria usage using the interface: var criteria = DetachedCriteria.For<ILocation>().Add(Restrictions.Eq("Name", "blah")); var locations = criteria.GetExecutableCriteria(UoW.Session).List<ILocation>(); Are there any issues with not using the hilo ID generator and/or with this approach in general?

  • ClassCastException When Calling an EJB Remotely that Exists on Same Server

    - by aaronvargas
    I have 2 ejbs. Ejb-A that calls Ejb-B. They are not in the same Ear. For portability Ejb-B may or may not exist on the same server. (There is an external property file that has the provider URLs of Ejb-B. I have no control over this.) Example Code: in Ejb-A EjbBDelegate delegateB = EjbBDelegateHelper.getRemoteDelegate(); // lookup from list of URLs from props... BookOfMagic bom = delegateB.getSomethingInteresting(); Use Cases/Outcomes: When Ejb-B DOES NOT EXIST on the same server as Ejb-A, everything works correctly. (it round-robbins through the URLs) When Ejb-B DOES EXIST on the same server, and Ejb-A happens to call Ejb-B on the same server, everything works correctly. When Ejb-B DOES EXIST on the same server, and Ejb-A calls Ejb-B on a different server, I get: javax.ejb.EJBException: nested exception is: java.lang.ClassCastException: $Proxy126 java.lang.ClassCastException: $Proxy126 I'm using Weblogic 10.0, Java 5, EJB3 Basically, if Ejb-B Exists on the server, it must be called ONLY on that server. Which leads me to believe that the class is getting loaded by a local classloader (on deployment?), then when called remotely, a different classloader is loading it. (causing the Exception) But it should work, as it should be Serialized into the destination classloader... What am I doing wrong?? Also, when reproducing this locally, Ejb-A would favor the Ejb-B on the same server, so it was difficult to reproduce. But this wasn't the case on other machines. NOTE: This all worked correctly for EJB2

  • iPhone UI layout debugging

    - by Cruinh
    I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.origin.x, currentView.frame.origin.y, currentView.frame.size.width, currentView.frame.size.height); currentView = currentView.superview; } I expect this should show me the coordinates and size of each element up the hierarchy from the given view to the app's root UIWindow element, with the coordinates for each element relative to its parent. However, that does not seem to be the case. In my current situation, I have a UI I'm trying to debug where every other time I rotate the device, the whole UI shifts up or down 20 pixels, yet the code block above reports exactly the same numbers every time. I tried calling the above code after as much as a second delay, but that the numbers still come out the same each time. Does anyone know a better way to inspect the screen coordinates of UI elements? If I can detect when one is wrong, I can compensate for the problem when it appears.

  • Where Not In OR Except simulation of SQL in LINQ to Objects

    - by Thinking
    Suppose I have two lists that holds the list of source file names and destination file names respectively. The Sourcefilenamelist has files as 1.txt, 2.txt,3.txt, 4.txt while the Destinaitonlist has 1.txt,2.txt. I ned to write a linq query to find out which files are in SourceList that are absent in DestinationFile list. e.g. here the out put will be 3.txt and 4.txt. I have done this by a foreach statement. but now I want to do the same by using LINQ(C#). Edit: My Code is List<FileList> sourceFileNames = new List<FileList>(); sourceFileNames.Add(new FileList { fileNames = "1.txt" }); sourceFileNames.Add(new FileList { fileNames = "2.txt" }); sourceFileNames.Add(new FileList { fileNames = "3.txt" }); sourceFileNames.Add(new FileList { fileNames = "4.txt" }); List<FileList> destinationFileNames = new List<FileList>(); destinationFileNames.Add(new FileList { fileNames = "1.txt" }); destinationFileNames.Add(new FileList { fileNames = "2.txt" }); IEnumerable<FileList> except = sourceFileNames.Except(destinationFileNames); And Filelist is a simple class with only one property fileNames of type string.

  • Recommendations, Asp.Net ObjectDataSource bind result of webservice call

    - by DerDres
    I need recommendations on how to solve / structure a solution to the following problem. In an asp.net web application i'll have to visualise results returned from a web service call. Im planning to use a repeater server control and bind this with an objectdatasource. The service returns a result of the form: public class SearchResult : IExtensibleDataObject { [DataMember] public Guid SearchId { get; set; } [DataMember] public DateTime Timestamp { get; set; } [DataMember] public int Offset { get; set; } [DataMember] public int TotalResults { get; set; } [DataMember] public IList<ResultDocumentData> Documents { get; set; } It is the collection of Documents that I need to visualise with a repeater which will be associated with an ObjectDataSource. The datasource should work on the type ResultDocumentData; the collection property in the class SearchResult. I think I need to wrap the call to the webservice in a dataaccess layer class, that will have a getDocuments method returning an IList, that the ObjectDataSource can use as its SelectMethod. I think I could make this work, but I would like to know how to do it in an elegant way. Can you give me general recommendations and/or recommendations for the following: WebProject Folderstructure + naming Naming conventions for the name of the service wrapper class Creating the service reference

  • How to change default locale in BIRT

    - by zlajo
    Hi everybody, I am working with the BIRT reporting engine and my current task is to implement internationalization for reports. We are using the webviewer to generate and download pdf reports. There is a parameter (__locale) which allows me to specify the locale that should be used to generate a report. So far everything works fine. There is an additional requirement I have not been able to implement, though. Additionally to the locale which is set by the http parameter there should also be the possibility to specify some kind of fallback locale. Take the following example: There are two property-files common_en_US.properties and common_en_GB.properties. The first locale to be used should be en_GB (__locale=en_GB). Everything works fine if the common_en_GB.properties file exist. But I would also like to tell BIRT to use common_en_US.properties if the en_GB-file cannot be found, which does not work as expected. I tried to solve this by manually setting the Java default locale before executing BIRT because I thought that BIRT would use the Java mechanism to resolve localized strings. Unfortunately this attempt does not work. Is there a different way to do what I would like to do? Is it possible to do something like that at all? Thanks a lot! Johannes

  • IList<Item> Collection Class accessing database

    - by Mike
    Hi, I have a database with Users. Users have Items. These Items can change actively. How do you access the items in a collection type format? For the user, I fill all the user properties at the time of instantiation. If I load the user's items at the time of the instantiation, and the items change, they will have old data. I was thinking, maybe I need an ItemCollection class and have that a field/property apart of the user class, that way to traverse all the user's items I could use a foreach loop. So, my question is, what is the best practice/best way of accessing the items from a database using some sort of collection? On accessing the particular Item, it needs to get the latest database information, and when the user does do a foreach loop, the latest item information must be available. I.e. What I'm trying to do Console.WriteLine(User.Items[3].ID); returns 5. //this updates the item information and saves it to the database. User.Items[3].ID = 13; //Add a new item to the database. User.Items.Add(new Item { id = 17}); foreach (Item item in User.Items) { //this would traverse all items in the database. //not some cached copy at the time of instantiation of the user. }

  • Windows theme affecting ListView header

    - by LihO
    I've created new Windows Forms Application (C#) with one simple form containing ListView. Then I changed the View Property to Details and increased the size of the font used in this ListView and here's the result: This is how it looks on Windows XP with Windows Classic theme: and here's the result with Windows XP theme: Creating the same Windows Forms Application in Visual C++ instead of C# yields same result. EDIT : Thanks to Kamil Lach, we already know that Visual Styles is what makes the appearance of ListView change. This can be avoided either by removing Application.EnableVisualStyles() call or by changing the Application.VisualStyleState. Both of these solutions yield the following result: This looks fine, but this change affects the appearance of other controls which is not good. I'd like my ListView to be the only control that is not affected by Visual Styles. I've also found similar questions that try to deal with it: Can you turn off visual styles/theming for just a single windows control? How do I disable visual styles for just one control, and not its children? Unfortunately, none of mentioned solutions works. Any C# solution that would make the ListView header have the correct height would be appreciated.

  • TypeError: Error #1009 - (Null reference error) With Flash.

    - by Wind Chimez
    I am not an expert in flash, but i do work with AS and tweak Flash projects , though not having deep expertise in it. Currently i need to revamp a flash website done by one another guy, and the code base given to me, upon execution is throwing the following error. "--- TypeError: Error #1009: Cannot access a property or method of a null object reference. at NewSite_fla::MainTimeline/__setProp_ContactOutP1_ContactOut_Contents_0() at NewSite_fla::MainTimeline/frame1() --" The structure of the project is like, it has the different sections split into different movie clips. There is no single main timeline, but click actions on different areas of seperate movie clips will take them between one another. All the AS logic of event handling are written inline in FLA , no seperate Document class exists. Preloader Movie clip is the first one getting loaded. As i understood the error is getting thrown initially itself, and it is not happening due to any Action script logic written inline, because it is throwing error even before hitting the first inline AS code. I am not able to figure Out what exactly it causing the problem, or where to resolve it. I really got stuck at this point. Any help will be great.I had not seen the particular solution i am looking for anywhere yet, though Error #1009 is common. I uploaded the fla, here ( http://tinyurl.com/249e95p ), for reference.It may not be working , since the included/refered video files and all are not there, but reviwing the action code/movie clips will be possible. Please let me know if somebody will be able to trace the issue exactly.

  • Properly declare delegation in Objective C (iPhone)

    - by Gordon Fontenot
    Ok, This has been explained a few times (I got most of the way there using this post on SO), but I am missing something. I am able to compile cleanly, and able to set the delegate as well as call methods from the delegate, but I'm getting a warning on build: No definition of protocol 'DetailViewControllerDelegate' is found I have a DetailViewController and a RootViewController only. I am calling a method in RootViewController from DetailViewController. I have the delegate set up as so: In RootViewController.h: #import "DetailViewController.h" @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, DetailViewControllerDelegate> //Error shows up here { //Some Stuff Here } //Some other stuff here @end In RootViewController.m I define the delegate when I create the view using detailViewController.delegate = self In DetailViewController.h: @protocol DetailViewControllerDelegate; #import "RootViewController.h" @interface DetailViewController : UITableViewController <UITextFieldDelegate> { id <DetailViewControllerDelegate> delegate; } @property (nonatomic, assign) id <DetailViewControllerDelegate> delegate; @end @protocol DetailViewControllerDelegate //some methods that reside in RootViewController.m @end I feel weird about declaring the protocol above the import in DetailViewController.h, but if I don't it doesn't build. Like I said, the methods are called fine, and there are no other errors going on. What am I missing here?

  • When developing a Microsoft Office Add-In (for Word), is it possible to store hidden metadata inform

    - by leftend
    I am trying to store metadata (basically a unique id) along with each cell of a table in a Word document. Currently, for the add-in I'm developing, I am querying the database, and building a table inside the Word document using the data that is retrieved. I want to be able to save any of the user's edits to the document, and persist it back to the database. My initial thought was to store a unique id along with each cell in the table so that I would be able to tell which records to update. I would also like to store some sort of "isChanged" flag within each cell so that I could tell which cells were changed. I found that I could add the needed information into the "ID" property of the cell - however, that information was not retained if the user saved the document, closed it, and re-opened it. I then tried storing the data by adding a data to the "Fields" collection - but that did not work and threw a runtime error. Here is the code that I tried: object t1 = Word.WdFieldType.wdFieldEmpty; object val = "myValue: " + counter; object preserveFormatting = true; tbl.Cell(i, j).Range.Fields.Add(tbl.Cell(i, j).Range, ref t1, ref val, ref preserveFormatting); This compiles fine, but throws this runtime error "This command is not available". So, is this possible at all? Or am I headed in the wrong direction? Thanks in advance.

  • How to find unique values in jagged array

    - by David Liddle
    I would like to know how I can count the number of unique values in a jagged array. My domain object contains a string property that has space delimitered values. class MyObject { string MyProperty; //e.g = "v1 v2 v3" } Given a list of MyObject's how can I determine the number of unique values? The following linq code returns an array of jagged array values. A solution would be to store a temporary single array of items, looped through each jagged array and if values do not exist, to add them. Then a simple count would return the unique number of values. However, was wondering if there was a nicer solution. db.MyObjects.Where(t => !String.IsNullOrEmpty(t.MyProperty)) .Select(t => t.Categories.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)) .ToArray() Below is a more readable example: array[0] = { "v1", "v2", "v3" } array[1] = { "v1" } array[2] = { "v4", "v2" } array[3] = { "v1", "v5" } From all values the unique items are v1, v2, v3, v4, v5. The total number of unique items is 5. Is there a solution, possibly using linq, that returns either only the unique values or returns the number of unique values?

  • spring - constructor injection and overriding parent definition of nested bean

    - by mdma
    I've read the Spring 3 reference on inheriting bean definitions, but I'm confused about what is possible and not possible. For example, a bean that takes a collaborator bean, configured with the value 12 <bean name="beanService12" class="SomeSevice"> <constructor-arg index="0"> <bean name="beanBaseNested" class="SomeCollaborator"> <constructor-arg index="0" value="12"/> </bean> </constructor-arg> </bean> I'd then like to be able to create similar beans, with slightly different configured collaborators. Can I do something like <bean name="beanService13" parent="beanService12"> <constructor-arg index="0"> <bean> <constructor-arg index="0" value="13"/> </bean> </constructor> </bean> I'm not sure this is possible and, if it were, it feels a bit clunky. Is there a nicer way to override small parts of a large nested bean definition? It seems the child bean has to know quite a lot about the parent, e.g. constructor index. I'd prefer not to change the structure - the parent beans use collaborators to perform their function, but I can add properties and use property injection if that helps. This is a repeated pattern, would creating a custom schema help? Thanks for any advice!

  • C# visually subclass datagridview control VS2005

    - by DRapp
    Maybe its something stupid, but I'm having a problem with a subclass of a DataGridView Control in VS2005 C#. I know I can subclass from almost anything by doing public class MyDataGridView : DataGridView {} no problem, and I put in some things / elements I want applicable globally. Now, I take this gridview and put into a custom user control that will contain other controls too. So I have something like created by the visual designer. I grab some buttons, label, and my derived "MyDataGridView" on it. public partial class MyCompoundDGVPlus : UserControl So, now, I can visually draw, move, change all sorts of settings as needed, no problem. Now, I want this "MyCompoundDGVPlus" class as the basis for other classes, of which I will manipulate settings specific, but want all to have the same look / feel, and otherwise similar flow, hence the derivations. I've even set the "modifiers" setting to public, so I SHOULD be able to modify any of the properties of the controls at any derived level. So, now, I create a new subclass of "MyFirstDetailedDGVPlus" derived from "MyCompoundDGVPlus". Ok visually, all the label, button, datagridview appear. However, now I want to specifically define the columns of the datagridview here in this class visually, but its locked. However, the LABEL on the form, I CAN get all the property settings.... What am I missing.
