I am trying to make asimple asp.net mobile Webform, that has one textbox, in wich a barcode scanner enters a barcode and a "return"

1.) How do i get the focus on the textbox on page load ? ( Please note that MOBILE textbox control has no setfocus)

Some things that did not work so far on the mobile Webform :
####################################################################
Private Sub SetFocus(ByVal FocusControl As Control)
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
RegisterStaTextBox id="TextBox1" runat="server"></mobile:TextBox>
</mobile:Form>
</body>

But this one get me the following error while executing (sorry for german, but i hope you, dear reader, get the point):

[ArgumentException: Auf der Seite "isHTML32", die System.Boolean zur?ckgibt und System.Web.Mobile.MobileCapabilities und System.String als Argumente akzeptiert, ist weder eine Ger?tefunktion mit dem Namen "isHTML32" noch eine ?ffentliche, nicht statische Methode vorhanden.]
What do I need to set / do additionally ? Anything about devicefilters in web.config ?

Any hint / help would be highly appreciated.

best regards,

Robin rtupScript("setFocus", Script.ToString())
End Sub
'This works perfect on normal Web Forms !

Another attempt taken from the internet is the followoing :

<%@ Register TagPrefix="mobile" Namespace="System.Web.UI.MobileControls" Assembly="System.Web.Mobile" %>
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MWnyatecSCANInput.aspx.vb" Inherits="NyatecSCANInput.MWnyatecSCANInput" %>

Robin,

I'm trying to do exactly the same thing in PIE and have been looking for a solution for three days. Please let me know if you find a solution. I have tried registering a client side script, it works on desktop browser but not on the mobile device.

If anyone has a solution to this one I would be very interested in seeing it.

Thanks
