Let’s say if you want to keep BtnSubmit as a default and have default focus on TextBox1 control, then all you have to do is, you have to add defaultbutton, defaultfocus attributes in server side form tag!! That’s it, you are done!!
After page load the default focus will be in TextBox1 and BtnSumbit will act as a default button! Haa. how simple it is… life is soooo easy now with 2.0 J
