Answer 1

Make use of keypress event of javascript + textbox

and call the serverside function by using ajax or using pagemthods.

.cs file
[ScriptMethod, WebMethod]

   public static string docall()
   {
      return "Hello";
   }

.aspx file

<script type="text/javascript">
      function btnAccept_onclic() {
          PageMethods.docall(onSuccess, onFailure);
      }

  function onSuccess(result) {
          alert(result);
      }


      function onFailure(error) {
          alert(error);
      } 

</script>
