Initial focus

Ok, VB-freaks...I'm sure this is an easy question to answer, but I've had no luck...

How does one set the initial focus on a web form? I tried SetInitialFocus(txtTextBox1), but it just advises me it's not declared. I tried to set the TabIndex, but no go there either...

hmmmm....Ooogs

Page.Controls.Add(new LiteralControl("<script Language=""JavaScript"">" & FindControl("ControlName").ID & ".focus();</Script>"))

You might have to play around with it a little.
