Id Set For .net Control When It Outputs To HTML?
Oct 1, 2010
When I create a form, I try to make accessibility a top priority, but the output from asp .NET negates some of this. For example, when I set a label tag for an input tag, I create it a such:
<label for="frmFirstName">First Name<span class="required">*</span></label>
<asp:TextBox id="frmFirstName" CssClass="textbox" runat="server" />
label for="frmFirstName">First Name<span class="required">*</span></label>
<input name="ctl00$phMainContent$frmFirstName" type="text" id="ctl00_phMainContent_frmFirstName" class="textbox" />

I have a custom control which is rendered as a hyperlink:
Public Class TestControl
Inherits System.Web.UI.WebControls.WebControl
Implements IPostBackEventHandler
Public Sub RaisePostBackEvent(ByVal eventArgument As String) Implements System.Web.UI.IPostBackEventHandler.RaisePostBackEvent
Trace.WriteLine("Hyperlink 1 clicked")
End Sub
Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
writer.WriteLine("<a href=""{0}"" id=""{1}"">Hyperlink 1</a>", _
Page.ClientScript.GetPostBackClientHyperlink(Me, "Hyperlink 1"), _
Me.ClientID)
End Sub
End Class
This works fine. It also works nicely when put inside an UpdatePanel: Only the UpdatePanel is refreshed, no full postback is performed.
Now I would like to output a second hyperlink in the Render method. If I use the same id (Me.ClientID), everything works nicely, but this obviously results in broken HTML (no two controls are allows to have the same id attribute). If I use different client IDs (like Me.ClientID & "_1" and Me.ClientID & "_2"), a full postback is performed when the hyperlinks are clicked.
Is there some way to tell ASP.NET AJAX: "All postbacks of the following client IDs should be done asynchronously: ..."?

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

I have a Web Deployment Project in my solution. The solution consists of the MVC2 App and another Class Library.
In the Web Deployment Project properties I have the Merge all outputs to a single assembly option ticked and I have given it a name.
When I look in the bin folder I have all my reference DLL's from my MVC app, a DLL with the name of my MVC project and then a DLL by then name I gave it when choosing the Merge all outputs to a single assembly option.
I imagined this option would create 1 DLL not all DLL's plus another one.

how I can add outputs to my vb.net functions? The reason for this is that I have functions which return data tables for grid views. But I also want to pass a return value back to the calling routine, so that it knows whether the function succeeded or failed. It would also be good to pass strings back too, in addition to the returned data table.

I am developing a software that uses number precision, but I have this problem, it happens that when I take a string to convert to double it outputs me with a different culture.
For example I use
Convert.ToDouble("4089.90"); // it outputs 40.899,00
Is strange cause in my computer it works OK but on the client's PC (with the same culture in regional settings) shows me the latter output. I know I can fix it using
Convert.ToDouble("4089.90", System.Globalization.CultureInfo.InvariantCulture);
But there is a lot of code in the program using "Convert.ToDouble" and I wouldn't like to change all of it, on the other hand I want to understand why this happens.

When a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?

I have a multi view which contains a view which contains a panel. the name of this panel is "Panel1"I have the following code and my HTML does not display in the rendered page. Any idea why this isn't working, i must be doing something wrong? sw = simple html statement, any would produce same result.
String mstring = sw.ToString();
Panel1.Controls.Add(new LiteralControl(mstring));
i am using dotnetnuke also, not sure if that is where the issue is.

How to wire up HTML server controls events?
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?
