How to set focus to a textbox or button on form load in ASP.Net without using javascript

Form Accessibility is important in improving the Usability of Web Pages.

On Form load of a ASP.Net page, you may want to set the focus to a TextBox.  In that case you don't have to write a javascript and call it on form's onLoad event.

You can simply use,
defaultfocus="<YourTextBoxID>" in the <form tag.

defaultbutton="<YourButtonID>" will set the specified Button  as the default button.

eg:
<form id="form1" runat="server" defaultfocus="TextBox1" defaultbutton="Button1">
</form >
