Thanks for your followup Sck10,
In your case, I think we can check the following things:
1. Make sure when you use the Page.SetFocus function, the passed in
Control Parameter instance's ClientID has be the actual value which will be
rendered out as its "id" in client side html element(you can print out this
and view the rendered html to compare it...)
2. Check the rendered javascript code in the rendered html in clientside
browser to see whether the clientside code is registered correctly...
Thanks,
Steven Cheng

| Thanks Steve,
|
| I am still having difficulties getting the sub procedure to work once
moved
| to the "App_code" folder. When I call the class using "Call
| class_General.SetFocusControl(Me.txtSearch)", I don't get an error, but it
| doesn't go to the control.
|
| Previously you said,
| > | Also, as I've mentioned in the former message, the "FocusControl" must

|
| I was wondering if this is what is happening and how can I test for this?
| Thanks again for any insight.
|
| Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
| 'Set Focus
| Call class_General.SetFocusControl(Me.txtSearch)
| ' this works: Call SetFocusControl(Me.txtSearch)
| End Sub
|
|
| This works
| ---------------------
| Public Shared Sub SetFocusControl(ByVal FocusControl As Control)
|
| 'class_General.SetFocusControl(Me.txtTravelerHRID)
|
| Dim Script As New System.Text.StringBuilder
| Dim ClientID As String = FocusControl.ClientID
| With Script
| .Append("<script language='javascript'>")
| .Append("document.getElementById('")
| .Append(ClientID)
| .Append("').focus();")
| .Append("</script>")
| End With
|
|
FocusControl.Page.ClientScript.RegisterClientScriptBlock(GetType(String),
| "SetFocusOnControl", Script.ToString())
|
| End Sub
|
|
| "App_Code" folder
| -----------------
| Imports Microsoft.VisualBasic
|
| Public Class class_General
| Public Shared Sub SetFocusControl(ByVal FocusControl As Control)
|
| 'class_General.SetFocusControl(Me.txtTravelerHRID)
|
| Dim Script As New System.Text.StringBuilder
| Dim ClientID As String = FocusControl.ClientID
| With Script
| .Append("<script language='javascript'>")
| .Append("document.getElementById('")
| .Append(ClientID)
| .Append("').focus();")
| .Append("</script>")
| End With
|
|
FocusControl.Page.ClientScript.RegisterClientScriptBlock(GetType(String),
| "SetFocusOnControl", Script.ToString())
|
| End Sub
|
| Thanks again,
