Set Focus on textbox when starting webpage

Question

When the webpage loads the focus is on the URL and not on the text box.

Code used: On Page load: TextBox1.Focus(); and SetFocus(TextBox1); - Neither work

On asp side on tried in content: defaultfocus="TextBox1"

and OnLoad="Focus_Textbox" calling function

protected void Focus_Textbox(object sender, EventArgs e) {
  TextBox1.Focus();
}

Answer 1

Just try this:

Focus_Textbox(object sender, EventArgs e)
{ 
   TextBox1.SetFocus;
}

I think this works fine with .Net 4.0..
