Last couple of days i have been trying to put focus to my control when the page loads in my ASP.NET application but failed.I' ve tried all the methods like TextBox.focus() Page_Load, Pre_Render events Page.SetFocus but nothing seems to work.What causes this problem?

 Take a look @ http://msdn2.microsoft.com/en-us/library/ms178231.aspx

Try the defaultFocus property of the form element.
