Set focus to textbox in ASP.NET Login control on page load

Question

I am trying to set the focus to the user name TextBox which is inside an ASP.NET Login control.

I have tried to do this a couple of ways but none seem to be working. The page is loading but not going to the control.

Here is the code I've tried.

SetFocus(this.loginForm.FindControl("UserName"));

And

TextBox tbox = (TextBox)this.loginForm.FindControl("UserName");
if (tbox != null)
{    
  tbox.Focus();
} // if

Answer 1

I'm using Page.Form.DefaultFocus and it works:

// inside page_load, LoginUser is the Login control
Page.Form.DefaultFocus = LoginUser.FindControl("Username").ClientID;

Answer 2

Are you using a ScriptManager on the Page? If so, try the following:

public void SetInputFocus()
{
    TextBox tbox = this.loginForm.FindControl("UserName") as TextBox;
    if (tbox != null)
    {
       ScriptManager.GetCurrent(this.Page).SetFocus(tbox);
    }
}

Update: Never used a multiview before, but try this:

protected void MultiView1_ActiveViewChanged(object sender, EventArgs e)
{
   SetInputFocus();
}
