  • Selecting the contents of an ASP.NET TextBox in an UpdatePanel after a partial page postback

    - by Scott Mitchell
    I am having problems selecting the text within a TextBox in an UpdatePanel. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls: A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and A TextBox Web control The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code: TextBox1.Text = "Whatever"; ScriptManager.RegisterStartupScript(this, this.GetType(), "Select-" + TextBox1.ClientID, string.Format("document.getElementById('{0}').select();", TextBox1.ClientID), true); The idea is that whenever a user chooses and item from the DropDownList there is a partial page postback, at which point the TextBox's Text property is set and selected (via the injected JavaScript). Unfortunately, this doesn't work as-is. (I have also tried putting the script in the pageLoad function with no luck, as in: ScriptManager.RegisterStartupScript(..., "function pageLoad() { ... my script ... }");) What happens is the code runs, but something else on the page receives focus at the conclusion of the partial page postback, causing the TextBox's text to be unselected. I can "fix" this by using JavaScript's setTimeout to delay the execution of my JavaScript code. For instance, if I update the emitted JavaScript to the following: setTimeout("document.getElementById('{0}').select();", 111); It "works." I put works in quotes because it works for this simple page on my computer. In a more complex page on a slower computer with more markup getting passed between the client and server on the partial page postback, I have to up the timeout to over a second to get it to work. I would hope that there is a more foolproof way to achieve this. Rather than saying, "Delay for X milliseconds," it would be ideal to say, "Run this when you're not going to steal the focus." What's perplexing is that the .Focus() method works beautifully. That is, if I scrap my JavaScript and replace it with a call to TextBox1.Focus(); then the TextBox receives focus (although the text is not selected). I've examined the contents of MicrosoftAjaxWebForms.js and see that the focus is set after the registered scripts run, but I'm my JavaScript skills are not strong enough to decode what all is happening here and why the selected text is unselected between the time it is selected and the end of the partial page postback. I've also tried using Firebug's JavaScript debugger and see that when my script runs the TextBox's text is selected. As I continue to step through it the text remains selected, but then after stepping off the last line of script (apparently) it all of the sudden gets unselected. Any ideas? I am pulling my hair out. Thanks in advance...

  • DRY-ing very similar specs for ASP.NET MVC controller action with MSpec (BDD guidelines)

    - by spapaseit
    Hi all, I have two very similar specs for two very similar controller actions: VoteUp(int id) and VoteDown(int id). These methods allow a user to vote a post up or down; kinda like the vote up/down functionality for StackOverflow questions. The specs are: VoteDown: [Subject(typeof(SomeController))] public class When_user_clicks_the_vote_down_button_on_a_post : SomeControllerContext { Establish context = () => { post = PostFakes.VanillaPost(); post.Votes = 10; session.Setup(s => s.Single(Moq.It.IsAny<Expression<Func<Post, bool>>>())).Returns(post); session.Setup(s => s.CommitChanges()); }; Because of = () => result = controller.VoteDown(1); It should_decrement_the_votes_of_the_post_by_1 = () => suggestion.Votes.ShouldEqual(9); It should_not_let_the_user_vote_more_than_once; } VoteUp: [Subject(typeof(SomeController))] public class When_user_clicks_the_vote_down_button_on_a_post : SomeControllerContext { Establish context = () => { post = PostFakes.VanillaPost(); post.Votes = 0; session.Setup(s => s.Single(Moq.It.IsAny<Expression<Func<Post, bool>>>())).Returns(post); session.Setup(s => s.CommitChanges()); }; Because of = () => result = controller.VoteUp(1); It should_increment_the_votes_of_the_post_by_1 = () => suggestion.Votes.ShouldEqual(1); It should_not_let_the_user_vote_more_than_once; } So I have two questions: How should I go about DRY-ing these two specs? Is it even advisable or should I actually have one spec per controller action? I know I Normally should, but this feels like repeating myself a lot. Is there any way to implement the second It within the same spec? Note that the It should_not_let_the_user_vote_more_than_once; requires me the spec to call controller.VoteDown(1) twice. I know the easiest would be to create a separate spec for it too, but it'd be copying and pasting the same code yet again... I'm still getting the hang of BDD (and MSpec) and many times it is not clear which way I should go, or what the best practices or guidelines for BDD are. Any help would be appreciated.

  • ASP.NET Ajax partial postback and jQuery problem

    - by chromaloop
    A control contains some HTML and some jQuery to handle a fancy tooltip to display when you click an image within a div. The control is then used on several different pages, sometimes within an updatePanel, sometimes not. I have the following code to handle loading the jQuery after a partial postback when the control is displayed within an update panel. Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, args) { $('img.ormdShipping').each(function(){ $(this).qtip({ // some qtip options go here }) }); } Problem is, the jQuery doesn't load when the control is used anywhere other than an updatePanel. Do I need a second function that's triggered outside of the EndRequestHandler?

  • .NET Generate email text in Outlook from Word

    - by Chapso
    I am attempting to generate the body of an email in Outlook 2007 from the text of a Word 2007 document in VB. I have access to both the Word and Outlook object libraries, and I can read from the Word document to get a string and write it to Outlook, but I need to keep the formatting from the Word document intact. The purpose will be to allow users to edit the word document and always have the emails my program generates be in sync with the document. Does anyone know how to do this?

  • Approaches for Error Code/Message Management in .NET

    - by WayneC
    Looking for suggestions/best practices on managing error codes and messages in a multi-tiered applications. Specifically things like: Where should error codes be defined? Enum? Class? How are error messages or further details associated with the error codes? resource files? attributes on enum values, etc.? If you have a multi-tier application consisting of DAL, BLL, UI, and Common projects for example, should there be a single giant list of codes for all tiers, or are the codes extensible by project/tier? Update: Important to mention that I can't rely solely on Exceptions and custom Exception types for error reporting, as some clients for this application will be via web services (SOAP & REST) Any suggestions welcome!

  • Asp.net Date Binding Issue with Nulls

    - by Matthew Kruskamp
    I have a nullable date in my database. I am connecting to it with a LinqDataSource, and binding with a FormView. It allows you to place dates fine, but if you remove the date I need it to insert the null value to the db. It is instead throwing an exception. <asp:TextBox ID="TxtStartDate" runat="server" Text='<%# Bind("StartDate", "{0:MM/dd/yyyy}") %>' /> Works fine if you place a date in it, but if you delete the date out of it and save, you get System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. How do I make it send null?
