One caveat to the StreamReader line you are using to read the script from the .js file is that it won't work as written if you are using namespaces below the root namespace for your assembly. Embedded Resources are located in the root namespace for the assembly.

If your control is named as follows: myAssembly.myWebControls.FooControl, then passing typeof(FooControl) to GetManifestResourceStream() will cause it to look in myAssembly.myWebControls for the embedded resource. However, it is not in myAssembly.myWebControls, it is in myAssembly.

The solution is to provide the fully qualified name for the resource, which is just as easy. Simply add the assembly name to the resource name, instead of passing the type. Like this:

using (System.IO.StreamReader reader = new System.IO.StreamReader(typeof(FooControl).Assembly.GetManifestResourceStream(typeof(FooControl).Assembly.GetName().Name + ".FooControl.js")))

Rather than deriving the namespace from the type you have passed, GetManifestResourceStream will just use the full name that you passed instead, and it will work regardless of what namespace the control is in.

use the below code to set focus in an aspx(System.Web.UI.page).

Now I covert the page into a web control ascx. The RegisterStartupScript method is not available in System.Web.UI.UserControl.

How can I set focus in web control?

Thanks,
Terrence

Private Sub SetFocus(ByVal CtrlName As String)
Dim strBuilder As StringBuilder = New StringBuilder
strBuilder.Append("<script language = 'javascript'>")
strBuilder.Append("var obj;")
strBuilder.Append("obj = document.getElementById('" & CtrlName & "');")
strBuilder.Append("if (obj){")
strBuilder.Append("document.getElementById('" & CtrlName & "').focus();")
strBuilder.Append("}")
strBuilder.Append("</script>")
RegisterStartupScript("focus", strBuilder.ToString)
End Sub

Whidbey's framework allows for "WebResources" whereas the JS files and possibly GIFs for Icons for controls can be embedded into the DLL and exposed as resources that aspnet_isapi will link to.

I just know I can't wait for Whidbey, but apparently its been delayed! arg!

var myFooControl = document.getElementById( fooControlProperties.ID );

Returns Null for myFooControl. (the ClientID is not there)

I like it. I may change my recommendation after looking into it.
