ASP.NET Set Focus by Scott Guthrie

Wow.

This is the cleanest solution to one of ASP.NET most common problems, setting focus:

Scott Guthrie notes in his Blackbelt WebForms presentation:

Sub SetFocus(ByVal controlToFocus As Control)



        Dim scriptFunction As New StringBuilder

        Dim scriptClientId As String



        scriptClientId = controlToFocus.ClientID



        scriptFunction.Append("<script language='javascript'>")

        scriptFunction.Append("document.getElementById('")

	scriptFunction.Append(scriptClientId)

	scriptFunction.Append("').focus();")

        scriptFunction.Append("</script>")



        RegisterStartupScript("focus", scriptFunction.ToString())



End Sub
