  • Gridview and Modal popup not updating

    - by rs
    I have page with following controls <asp:UpdatePanel ID="up1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <uc2:CountryControl ID="Country1" runat="server" /> <br class = "br_e" /> <br class = "br_e" /> <asp:UpdatePanel ID="upCountry2" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Panel runat="server" ID="pnCountry" Width="400px" Visible="false"> <asp:GridView ID="gvCountry" runat="server" AllowSorting="true" DataKeyNames="countryid" DataSourceID="data_country1" AutoGenerateColumns="false"> <Columns> <asp:CommandField ButtonType="Link" ShowDeleteButton="true" /> <asp:BoundField HeaderText="Country" DataField="CountryName" SortExpression="CountryName" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="data_country1" runat="server" ConnectionString="<%$ zyx %>" SelectCommand="xyz" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:SessionParameter Name="country" DefaultValue="" ConvertEmptyStringToNull="true" SessionField="CountryID" Type="String" /> </SelectParameters> </asp:SqlDataSource> </asp:Panel> </ContentTemplate> </asp:UpdatePanel> </ContentTemplate> </asp:UpdatePanel> My user control is a modal popup to select country and add selected ids to a session variable. And in main page bind data using ids in session variable.Gridview - on deleting event i'm deleting that id from session and on deleted event updating both user control using a refresh method (Country1.Refresh()) and gridview panel. But updatepanel is not getting updated and even modalpopup is also not getting refreshed. What could be wrong here? Even though update and refresh events are fired and executed, why is page not getting updated?

  • Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

    - by user295479
    Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

  • Error when changing default lanuage in asp.net compilation from vb to c#

    - by Herman
    Hi all, We have a updatable web site project that is written in c#, it has the usual web form implementation using master page, skins, user controls,...etc. Up to this point we neglect to change the default compilation language from VB to C#. However, the second we change it, we see the following error. Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ASP.Default.__DataBinding__control499(Object sender, EventArgs e) at System.Web.UI.Control.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at .... Further investigation points out that this error is getting generated from a Theme related assembly (Source : App_Theme_Default.zclakrlo). Any ideas? One of my co-worker suggested that it might be skin file related since we have a theme call "Default" and there is no way to specify a language on a skin file. Therefore, when the asp.net runtime tries to compile it under C#, it will give a name collision? Does this make sense? Any help is appreciated.

  • Broken tables in RichTextBox control (word wrap)

    - by Ben Robbins
    We are having problems with the Windows.Forms.RichTextBox control in Visual Studio 2008. We are trying to display text supplied as an RTF file by a 3rd party in a windows forms application (.NET 3.5). In this RTF text file there are tables, which contain text that spans multiple lines. The RTF file displays correctly when opened with either WordPad or Word 2003. However, when we load the RTF file into the RichTextBox control, or copy & paste the whole text (including the table) into the control, the table does not display correctly - the cells are only single line, without wrapping. Here are links to images showing the exact problem: Correctly displayed in WordPad Incorrectly displayed in RichTextBox control I have googled for solutions and 3rd party .net RTF controls without success. I have found this exact problem asked on another forum without an answer (in fact that's where the link to the images come from) so I'm hoping stack overflow does better ;-) My preferred solution would be to use code or a 3rd party control that can correctly render the RTF. However, I suspect the problem is that the RichTextBox control only supports a subset of the full RTF spec, so another option would be to modify the RTF directly to remove the unsupported control codes or otherwise fix the RTF file itself (in which case any information as to what control codes need to be removed or modified would be a huge help).

  • HTML5 video - Safari (Mac) - live HLS stream - seek in live buffer

    - by bsnote
    I have the following HTML: <head> </head> <body> <button type="button" onclick="onSeek();">Seek</button> <video id="video" src="http://<host>/somevideo.m3u8" autoplay controls> </video> <script src="http://code.jquery.com/jquery-1.7.2.min.js"></script> <script> function onSeek() { var video = $('#video')[0]; video.currentTime = -300; } </script> </body> When I open the page, the m3u8 playlist has already about 100 media segments (5 min). Since it's a live video it starts playing from one of the last media segments and video.currentTime is set to 0. video.seekable.start(i) and video.seekable.end(i) shows the seekable range which is 0..currentTime. How can I seek to the previous media segments, say 5 min back? video.currentTime = -300 doesn't work. It resets currentTime to 0.

  • Access VBA sub with form as parameter doesn't alter the form

    - by Ski
    I have a Microsoft Access 2003 file with various tables of data. Each table also has a duplicate of it, with the name '[original table name]_working'. Depending on the user's choices in the switchboard, the form the user choose to view must switch its recordsource table to the working table. I refactored the relevant code to do such a thing into the following function today: Public Sub SetFormToWorking(ByRef frm As Form) With frm .RecordSource = rst![Argument] & "_working" .Requery Dim itm As Variant For Each itm In .Controls If TypeOf itm Is subForm Then With Item Dim childFields As Variant, masterFields As Variant childFields = .LinkChildFields masterFields = .LinkMasterFields .Form.RecordSource = .Form.RecordSource & "_working" .LinkChildFields = childFields .LinkMasterFields = masterFields .Form.Requery End With End If Next End With End Sub The lines of code that call the function look like this: SetFormToWorking Forms(rst![Argument]) and SetFormToWorking Forms(cmbTblList) For some reason, the above function doesn't change the recordsource for the form. I added the 'ByRef' keyword to the parameter just to be certain that it was passing by reference, but no dice. Hopefully someone here can tell me what I've done wrong?

  • Asynchronously populate datagridview in Windows Forms application

    - by dcryptd
    howzit! I'm a web developer that has been recently requested to develop a Windows forms application, so please bear with me (or dont laugh!) if my question is a bit elementary. After many sessions with my client, we eventually decided on an interface that contains a tabcontrol with 5 tabs. Each tab has a datagridview that may eventually hold up to 25,000 rows of data (with about 6 columns each). I have successfully managed to bind the grids when the tab page is loaded and it works fine for a few records, but the UI freezes when I bound the grid with 20,000 dummy records. The "freeze" occurs when I click on the tab itself, and the UI only frees up (and the tab page is rendered) once the bind is complete. I communicated this to the client and mentioned the option of paging for each grid, but she is adament w.r.t. NOT wanting this. My only option then is to look for some asynchronous method of doing this in the background. I don't know much about threading in windows forms, but I know that I can use the BackgroundWorker control to achieve this. My only issue after reading up a bit on it is that it is ideally used for "long-running" tasks and I/O operations. My questions: How does one determine a long-running task? How does one NOT MISUSE the BackgroundWorker control, ie. is there a general guideline to follow when using this? (I understand that opening/spawning multiple threads may be undesirable in certain instances) Most importantly: How can I achieve (asychronously) binding of the datagridview after the tab page - and all its child controls - loads. Thank you for reading this (ahem) lengthy query, and I highly appreciate any responses/thoughts/directions on this matter! Cheers!

  • Sharepoint.OpenDocuments Control Compatible with Forms Authentication?

    - by Richard Collette
    We are using the Sharepoint.OpenDocuments.EditDocument2 ActiveX control and method. The method is being called from JavaScript in an IE6 client on a Windows XP SP3 client (fully patched). The server is running IIS6 on Windows Server 2003 SP1 Fronting the IIS server is Tivoli Access Manager (TAM) which proxies access to the web applications sitting behind it. Similar to forms authentication, it creates a session cookie for authentication purposes, that must be present for the HTTP request to reach the IIS server. In front of TAM is an F5/BigIP load balancer and SSL encryption offloader, which enforces that incoming requests use the HTTPS protocol. What is happening is that HTTP requests issued by this control do not contain any session cookies that were present in the browser. It drops the ASP.NET session cookie, the ASP.NET forms authentication cookie and the TAM cookie Because the TAM cookie is missing the request is redirected to the TAM login page, which then shows up via HTML conversion in Word or Excel. The API documentation at http://msdn.microsoft.com/en-us/library/ms440037.aspx mentions nothing about security or appropriate usage scenarios for this control. Should these controls work in an ASP.Net Forms Authentication scenario or are they only supported with Windows Authentication. If Forms Authentication is supposed to function, how do we get the control to include the necessary session cookies in its requests?

  • How to group strings by prefix

    - by namenlos
    I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

  • Good ways to dynamically generate the start image of an iPhone/iPad app

    - by Dr Dork
    I'm self-learning iPhone development and I see that one of the aspects of an iPhone/iPad app is the start image that gets displayed when your app is run. I'd like my start image to display some basic info about the user when the app is launched, but that info has to first be collected by the user when the app is first run. That tells me that I either need to dynamically generate the start image after the user enters their information or I need to place a label of some sort on top of my static start image in order to accomplish this. The first time the app launched and before the user enters their info, the start image can be anything or nothing at all, I'm not concerned about this. So, my two questions are this... Can you place controls, like a label, on top of the start image when your app is launched? If not, what's a good approach to dynamically generating the start image after the app is launched for the first time and the user info is collected? Thanks so much in advance for your help! I'm going to begin researching this question right now.

    Hi! I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel: <asp:UpdatePanel ID="UpdatePanelNew" runat="server"> <ContentTemplate> <asp:Image ID="Image1" ImageUrl="~/Images/Categories/NoCategory.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> <asp:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete" runat="server" ID="AsyncFileUpload1" UploadingBackColor="#CCFFFF" ThrobberID="myThrobber" /> &nbsp; <asp:Label ID="myThrobber" runat="server" Style="display: none;"> <img align="middle" alt="Working..." src="../../Images/App/uploading.gif" /> </asp:Label> in C# code I wrote these: protected void Page_Init() { AsyncFileUpload1.UploadedComplete += new EventHandler<AsyncFileUploadEventArgs>(AsyncFileUpload1_UploadedComplete); } void AsyncFileUpload1_UploadedComplete(object sender, AsyncFileUploadEventArgs e) { ScriptManager.RegisterStartupScript(this, this.GetType(), "size", "top.$get(\"" + uploadResult.ClientID + "\").innerHTML = 'Uploaded size: " + AsyncFileUpload1.FileBytes.Length.ToString() + "';", true); string savePath = MapPath("~/Images/Categories/" + Path.GetFileName(e.filename)); ImageOperations.ResizeFromStream(savePath, 128, AsyncFileUpload1.FileContent); Image1.ImageUrl = "~/Images/Categories/" + AsyncFileUpload1.FileName; //AsyncFileUpload1.SaveAs(savePath); } But it does not work. can you help me? Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I used UpdatePanelNew.Update(); but it does not work!

  • How to deal with calculated values with Dependency Properties on a custom WPF control

    - by jpierson
    To summarize what I'm doing, I have a custom control that looks like a checked listbox and that has two dependency properties one that provides a list of available options and the other that represents a enum flag value that combines the selection options. So as I mentioned my custom control exposes two different DependencyProperties, one of which is a list of options called Options and the other property called SelectedOptions is of a specific Enum type that uses the [Flags] attribute to allow combinations of values to be set. My UserControl then contains an ItemsControl similar to a ListBox that is used to display the options along with a checkbox. When the check box is checked or unchecked the SelectedOptions property should be updated accordingly by using the corresponding bitwise operation. The problem I'm experiencing is that I have no way other than resorting to maintaining private fields and handling property change events to update my properties which just feels unatural in WPF. I have tried using ValueConverters but have run into the problem that I can't really using binding with the value converter binding so I would need to resort to hard coding my enum values as the ValueConverter parameter which is not acceptable. If anybody has seen a good example of how to do this sanely I would greatly appreciate any input. Side Note: This has been a problem I've had in the past too while trying to wrap my head around how dependency properties don't allow calculated or deferred values. Another example is when one may want to expose a property on a child control as a property on the parent. Most suggest in this case to use binding but that only works if the child controls property is a Dependency Property since placing the binding so that the target is the parent property it would be overwritten when the user of the parent control wants to set their own binding for that property.

  • Why does Cut/Paste of form components sometimes stop working in Delphi 2007 IDE?

    - by robsoft
    This is driving me crazy. I'm not going to take it anymore. I'm going to ask, even at the risk of eternal public humiliation! (If it's something really obvious or that I've done to the system myself). For reasons I've never quite had the patience to work out, every so often the form I'm working on in Delphi 2007's visual form editor goes 'pseudo-read-only'; I can add new components to the form, I can move/resize existing ones (and change any properties in the Object Inspector), and I can select a component and 'copy' it to the clipboard. But I'm completely unable to cut a component from the form, or paste a new copy down. I don't believe it's to do with the 'Lock Controls' Edit menu option as I can toggle this on or off and it has the effect it's supposed to - this disappearance of Cut & Paste happens on the right-click context menu, from the keyboard and from the main Edit menu - it's as if the form has become read only to thing to do with the clipboard. If I close the form in the IDE and then reopen it, everything starts working fine again (just as D1, D3, D5 and D7 always did for me, previously). I'm not going mad, as I'm sure I read something about why this happens on a newsgroup once and it's caught me out from time to time many many times in the last few months, but I've failed to find the newsgroup reference this evening and I've decided that, as more and more Delphi users seem to be making use of StackOverflow, it was worth asking here. Help - when I'm doing lots of form-work it drives me absolutely mad!

  • WPF MVVM Chart change axes

    - by c0uchm0nster
    I'm new to WPF and MVVM. I'm struggling to determine the best way to change the view of a chart. That is, initially a chart might have the axes: X - ID, Y - Length, and then after the user changes the view (either via lisbox, radiobutton, etc) the chart would display the information: X - Length, Y - ID, and after a third change by the user it might display new content: X - ID, Y - Quality. My initial thought was that the best way to do this would be to change the bindings themselves. But I don't know how tell a control in XAML to bind using a Binding object in the ViewModel, or whether it's safe to change that binding in runtime? Then I thought maybe I could just have a generic Model that has members X and Y and populate them as needed in the viewmodel? My last thought was that I could have 3 different chart controls and just hide and show them as appropriate. What is the CORRECT/SUGGESTED way to do this in the MVVM pattern? Any code examples would be greatly appreciated. Thanks

  • ASP.NET Ajax - Asynch request has separate session???

    - by Marcus King
    We are writing a search application that saves the search criteria to session state and executes the search inside of an asp.net updatepanel. Sometimes when we execute multiple searches successively the 2nd or 3rd search will sometimes return results from the first set of search criteria. Example: our first search we do a look up on "John Smith" - John Smith results are displayed. The second search we do a look up on "Bob Jones" - John Smith results are displayed. We save all of the search criteria in session state as I said, and read it from session state inside of the ajax request to format the DB query. When we put break points in VS everything behaves as normal, but without them we get the original search criteria and results. My guess is because they are saved in session, that the ajax request somehow gets its own session and saves the criteria to that, and then retrieves the criteria from that session every time, but the non-async stuff is able to see when the criteria is modified and saves the changes to state accordingly, but because they are from two different sessions there is a disparity in what is saved and read. EDIT::: To elaborate more, there was a suggestion of appending the search criteria to the query string which normally is good practice and I agree thats how it should be but following our requirements I don't see it as being viable. They want it so the user fills out the input controls hits search and there is no page reload, the only thing they see is a progress indicator on the page, and they still have the ability to navigate and use other features on the current page. If I were to add criteria to the query string I would have to do another request causing the whole page to load, which depending on the search criteria can take a really long time. This is why we are using an ajax call to perform the search and why we aren't causing another full page request..... I hope this clarifies the situation.

Write such code: using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public class Form1 : Form { private readonly Button button1 = new Button(); private readonly ComboBox comboBox1 = new ComboBox(); private readonly TextBox textBox1 = new TextBox(); public Form1() { SuspendLayout(); textBox1.Location = new Point(21, 51); button1.Location = new Point(146, 49); button1.Text = "button1"; button1.Click += button1_Click; comboBox1.Items.AddRange(new[] {"1", "2", "3", "4", "5", "6"}); comboBox1.Location = new Point(21, 93); AcceptButton = button1; Controls.AddRange(new Control[] {textBox1, comboBox1, button1}); Text = "Form1"; ResumeLayout(false); PerformLayout(); } private void button1_Click(object sender, EventArgs e) { comboBox1.DroppedDown = true; } } } Then, run app. Place mouse cursor on the form and don't touch mouse anymore. Start to type something in TextBox - cursor will hide because of it. When you press Enter key - event throws and ComboBox will be dropped down. But now cursor won't appear even if you move it! And appears only when you click somewhere. There I've found discussion of this problem. But there's no good solution... Any thoughts? :)

  • VB.Net Custom Object Master-Detail Data Binding

    - by clawson
    Since beginning to use VB.Net some years ago I have become slowly familiar with using the data binding features of .Net, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on. Needless to say my problems continue to arise. I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the DataBindingSource for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the DataSource of the BindingSource. (That's a mouthful!) Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a DataGridView. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the DataGridView won't update with the new items. So my question really has a few layers: How can I easily/efficiently/correctly update this DataGridView with the list of Detail objects when I add them to the list of the Master object. Is this approach to DataBinding good/viable. What's the best way to separate business logic from graphical interface. Thanks for the help!

  • Problem with response.redirect sending incorrect HTTPMethod

    - by Andy Macnaughton-Jones
    Hi, I've got a strange problem with a Response.Redirect. I'm using VB.NET with the .NET 2 framework (so VS2005 & SP1). I've got a page that I do a form submit on (that's a proper form method="POST" hard-coded onto the page) and that properly posts me back the page data which is then processed. As part of that processing the system determines if we need to get sent to another URL after processing has been complete. So the request.httpmethod = "POST". So if the "GotoPage" parameter has a URL specified we then do a response.redirect(URL, false). (False as we want page processing to complete in order to write some timing logs etc). The page correctly redirects but instead of the response having a "GET" as the request.httpmethod it has a "POST" instead ! Now, we're using our own custom framework so that we use the HTTPRequest method to determine if a page has been posted back or is being "Getted" so the "IsPagePostBack" property doesn't work (that only works when you're using the normal .NET controls and form submissions). In all other instances our code works happily but what might be causing the Request.httpMethod to not be being set correctly ? I've tried doing a response.clear before the redirect in case headers are being written out before hand but to no avail. Any clues ?! thanks, Andy
