SetFocus to asp:TextBox within asp:Panel within asp:Content from content Page Load event

Question

I have an asp web page(login.aspx) that uses a master page (master.page).

I need to set focus to an asp:textbox(TextBox1) that is inside an asp:Panel(Panel1) on Login.aspx

I want to set focus to TextBox1 on an asp:Button click event (or page load on login.aspx for testing, I've tried both).

I have tried the following solutions with no success:

• Page.SetFocus(TextBox1.ClientID);
• Page.SetFocus(TextBox1);
• Page.SetFocus(TextBox1.ClientID)
• TextBox1.Focus();
• TextBox Test = (TextBox)Panel1.FindControl("TextBox1");
• Test.Focus();

Ok I found the answer, the code works fine in IE8 But not firefox for some reason

Anyone know why SetFocus() or Focus() doesn't work in firefox, are there any solutions?

When using ASP.NET AJAX I use the ScriptManager to set focus...

ScriptManager.GetCurrent(this.Page).SetFocus(this.FirstNameTextBox);
