Focus particular textbox in page bydefault (like google) & on enter key press hit button from page(like google search button)

This are very easy things to do,

when we open any page and we want particular textbox contains cursor & after pressing enter button particular button gets clicked then do the following things.

In asp.net page contains a form tag, It contains defaultbutton & defaultfocus attributes set it as per your requirement

defaultbutton:= give your buttons name which u want to clicked
defaultfocus:= give control name for which you want focus after page load

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

 Here  TextBox1 contains cursor & after press enter Button1's click event gets called.

Happy Coding !!
