<asp:TextBox runat="server" onkeyPress="MyKeyPressEvent;" ID="txtUserName" />

Just add the onkeyPress client event to your textbox.

Then in your JavaScript function "MyKeyPressEvent", call a PageMethod that fires your event method.

Pagemethods are good with onkeyPress, since they have very small Request sizes.

you can use javascript and pagemethods to make it as efficient as possible

use the onkeyup to call a function where you call your pagemethod

Going to have to use ajax since the keypress is a client side event.
