  • ASP.NET GridView - how to enable validation declaratively

    - by Joe
    It it possible to enable validation in an ASP.NET GridView purely declaratively? What I've tried: A GridView bound to an ObjectDataSource with SelectMethod and UpdateMethod defined The GridView contains some ReadOnly BoundField columns and a TemplateField whose EditTemplate contains a TextBox and a RegularExpressionValidator that only allows numeric input in the TextBox. The GridView also contains a CommandField with ShowEditButton=true and CausesValidation=true. If I click on Edit, enter an invalid value, then click on Save, there is a PostBack, and an exception is thrown in the server (Input string was not in a correct format). I can of course avoid this by adding validation code to the RowUpdating event handler on the server (see below), but is there any declarative way to force the validation to be done without adding this code? protected void MyGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) { Page.Validate("MyValidationGroup"); if (!Page.IsValid) { e.Cancel = true; } }

  • File System Types in .Net

    - by Avi
    I don't get the abstractions and the terminology :-( For example, DirectoryInfo.FullName is defined as the full path of the directory or file, but it's a string! So is DirectoryInfo.Name, FileInfo.FullName, Path.GetDirectoyName and so on. This means that in .Net there is no "depth" (or "meat" - my English isn't so good) for the file system objects. There's no protection from a type system. I can't, for example, define two Path objects and ask if one of them is "above" the other - I have to manipulate the strings. I can't differentiate between a Path that identifies a directory and a path that identifies a file. I can't do anything!-( Just manipulate strings. Is this correct (or am I simply missing something). If correct, are there any alternatives?

  • vb.net more performance for moving objects

    - by René
    I have the mission to make a small game for a school project. Pictures boxes, moved by a timer for walking enemies.If there are around 5 or 6 moving picture boxes at the form, my application get troubles and lags. After I kill some enemies (remove them from the Controls Collection of the Form/Panel) It come back smooth. I think the loop of the enemy movement is too complicated but I don't know how to make that simpler. Private Sub TimerEnemyMovement_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TimerEnemyMovement.Tick For Each Enemy As Control In PanelBackground.Controls If Enemy.Name.Substring(0, 5) = "Enemy" Then _enemy.MoveEnemy(Enemy, 2) End If Next End Sub I also thought about Multithreading but not sure this would solve the problem and there is also the problem that I can't access the Controls of my mainform. You see, I don't have much knowledge about vb.net Any ideas how to fix that lag?

  • ASP.NET Speed up DataView sorting/paging

    - by rlb.usa
    I have a page in ASP.NET where I'm using a Repeater to display a record listing. But it's slow as molasses, I've been tasked with speeding it up (sorting,paging). I've got it set up as follows: When user enters page, grab all of the data from the database (500 records, up to 4 relation'ed records) Store it all in Application["MyDataView"] On sort or paging, simply use the data view's internal sort/page method (no db calls) and rebind. I understand that databases can take time to query, but simply to have the DataView call it's sort method (no db calls) takes 10ish seconds, that's an alarmingly slow. Two questions: Why is it taking so long? How can I speed it up? A gridview is not possible.

  • Allow users to enter a variable length list of items in asp.net form

    - by EJB
    I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

  • ASP.NET MVC Model Binders, html id

    - by Stacey
    Using the Model Binders in ASP.NET MVC 2.0, you can do something like this... [DisplayName("User Name")] public string Name { get; set; } <%: Html.TextBoxFor( m => m.Name ) :%> and then in your HTML, you get a result like this.. <label for="UserName">User Name</label> <input type="text" id="UserName" name="UserName" /> That works fine, but I want to have better control over the HTML ID. Is there any way to do this through the model binding method?

  • Creating installers in .net

    - by Manish
    I want to create a installer which would just dump few files and folders at a location specified by user. But the problem is these files are required to be picked up from a fixed source folder and then the installer is build. Also, these files may change any time and then again a new version of the installer is required to be created. I want to do this in .Net using Setup and Deployment project. I'm not sure how to do this. Do I need to create another class library project with a Setup Poject? Does anyone has any idea?

  • Image equivalent of ActionLink in ASP.NET MVC

    - by Jason Whitehorn
    In ASP.NET MVC is there an equivalent of the Html.ActionLink helper for Img tags? I have a controller action that outputs a dynamically generated JPEG and I wanted to use the same Lambda expressions to link to it as I do HREFs using ActionLink. Alternatively, a helper that just gives the URL to a route (again specified using Lambdas) would also be acceptable. EDIT: I had originally specified that I was using Preview 5, however I see that a Beta has been released. So all-in-all the version number was an unneeded piece of info as I may be upgrading soon :-)

  • Using Large Arrays in VB.NET

    - by Tim
    I want to extract large amounts of data from Excel, manipulate it and put it back. I have found the best way to do this is to extract the data from an Excel Range in to a large array, change the contents on the array and write it back to the Excel Range. I am now rewriting the application using VB.NET 2008/2010 and wish to take advantage of any new features. Currently I have to loop through the contents of the array to find elements with certain values; also sorting large arrays is cumbersome. I am looking to use the new features, including LINQ to manipulate the data in my array. Does anybody have any advice on the easiest ways to filter / query, sort etc. data in a large array. Also what are the reasonable limits to the size of the array? ~Many Thanks

  • Connection to embedded device with Windows and .Net

    - by tim
    I am building a .net application(xp, vista, 7) that will communicate with an embedded device. I will be able to connect via IP, serial port and modem. Question: Should I allow some type of open connection within my application that will allow me to connect to the device through some other channels that may be set up in the operating system just to allow future extensibility without really having to change anything on the device? I was just imagining that the operating system would be able to serve all communication channels that may be setup through the operating system to the device. Like would an admin setup some channel through SMTP or other protocol. I just didn’t want to box myself in and ignore some more open architecture. Thanks.

  • Json.Net CustomSerialization

    - by BonyT
    I am serializing a collection of objects that contains a dictionary called dynamic properties. The default Json emitted looks like this: [{"dynamicProperties":{"WatchId":7771,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5580"}}, {"dynamicProperties":{"WatchId":7769,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5574"}}, {"dynamicProperties":{"WatchId":7767,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5572"}}, {"dynamicProperties":{"WatchId":7765,"Issues":0,"WatchType":"y","Location":"Equinix Source","Name":"highlight_SM"}}, {"dynamicProperties":{"WatchId":8432,"Issues":0,"WatchType":"y","Location":"Test Devices","Name":"Cisco1700PI"}}] I'd like to produce Json that looks like this: [{"WatchId":7771,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5580"}, {"WatchId":7769,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5574"}, {"WatchId":7767,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5572"}, {"WatchId":7765,"Issues":0,"WatchType":"y","Location":"Equinix Source","Name":"highlight_SM"}, {"WatchId":8432,"Issues":0,"WatchType":"y","Location":"Test Devices","Name":"Cisco1700PI"}] From reading the Json.Net documentation it looks like I could build a CustomContractResolver for my class, but I cannot find any details on how to go about this... Can anyone shed any light on the direction I should be looking in?

    - by ghawkes
    I am writing a .NET 3.5 WPF application in C#. This application needs to be able to get the URL(s) out of the browser window when it is in the foreground. I already have the code working that handles a global Windows hotkey and then checks to see if the foreground IntPtr is from a browser. If so, I am able to obtain the System.Diagnostics.Process objects that maps to the browser. At this point, I would like to obtain the URL(s) from the browser. Thank you, G

    Hi All, I am setting up a Continuous Integration server. I have one issue that doesn't seem to be mentioned in the tutorials. I have a ASP.net Web Application that I need to compile and them publish. My Problem is that I seem to be able to compile the app but when I attempt to use a buildPublisher this copies every thing including .svn files & folders and ms CS files. I am using an MSBuild task to compile my source. I tried setting my MSBuild Output Directory to directory but this didn't seem to have any effect. What am I not understanding? Thanks

  • Communication between .net winform and webform

    - by Pablo
    Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

  • asp.net mvc - limit access to web pages

    - by niao
    Greetings, in my asp.net mvc application what i would like to do is to enable access to some pages only after user was successfully authorized. I have already created custom membership provider and that works fine. How can I, in web config create such rule - for instance for all pages in ~Admin/ folder? I don't want to create on every controller's action the validation code. For now i have in my web.config the following statement: <location path="~/Admin"> <system.web> <authorization> <deny users="?"/> </authorization> </system.web> but it doesn't work.

  • asp.net global resources problem

    - by Bystrik Jurina
    Hello. I have a weird problem with global resources in my asp.net mvc web application. I have some resources in separate project(not a web app project). Those resources have following settings: Build action: Embedded Resource, Copy To Output Directory: Do not copy, Custom Tool: ResXFileCodeGenerator. When I change an existing value in resource file, build solution in release mode and upload neccesary dll files back to server, the previous values in resources are still shown. However, when I add a new key into resource file, the value of this key is shown properly. I do not have this problem during debugging on localhost. Thanks

  • Shared data in an ASP.NET application

    - by Barguast
    I have a basic ASP.NET application which is used to request data which is stored on disk. This is loaded from files and sent as the response. I want to be able to store the data loaded from these files in memory to reduce the number of reads from disk. All of the requests will be asking for the same data, so it makes sense to have a single cache of in-memory data which is accessible to all requests. What is the best way to create a single accessible object instance which I can use to store and access this cached data? I've looked into HttpApplication, but apparently a new instance of this is created for parallel requests and so it doesn't fit my needs.
