Hi,

Thank you for your response. I have made the adjustments to the code, but it still does not set focus on the login textbox when I run the application and click the TargetControl of the ModalPopupExtender.

Here is my code for the page...

[code behind]

 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        '====================== Java Code for ModalPopup TextBox focus ======================='
        If Not Page.IsPostBack Then
            If (Not Me.ClientScript.IsStartupScriptRegistered("Startup")) Then
                Dim scriptString = "<script type='text/javascript'>" _
                & "Sys.Application.add_load(modalSetup);" _
                & "function SetFocusOnControl() {" _
                & "$get('" _
                & txtUsername.ClientID _
                & "').focus(); }" _
                & "function modalSetup() {" _
                & "var modalPopup = $find('" _
                & ModalPopupExtender1.ClientID _
                & "');" _
                & "modalPopup.add_shown(SetFocusOnControl); }" _
                & "</script>"


                Me.ClientScript.RegisterStartupScript(Me.GetType(), "Startup", scriptString)
            End If
        End If
        '=================== End Java Code for ModalPopup TextBox Focus ====================='

    End Sub

  When debugging, the script appears to register. It just doesn't seem to be doing anything. Can you see any issues with my code?
