Hi divyasrinivasan,

This is for validating textbox for numeric only :

ASP.NET Syntax (Toggle Plain Text) 
  1. <%@ Page Language="VB" AutoEventWireup="false" CodeFile="OperationSheetMultipleArticle.aspx.vb" Inherits="OperationSheetMultipleArticle" EnableSessionState="true" %>
  2. <%@ OutputCache Location="Client" duration="5" varybyparam="none" %>
  3. <html xmlns="http://www.w3.org/1999/xhtml" >
  4. <script type="text/javascript" language=javascript>
  5. function keyDownNumber()
  6. { 
  7.     var key;    
  8.     if(navigator.appName == 'Microsoft Internet Explorer')
  9.         key = event.keyCode;
  10.     else
  11.         key = event.which
  12.  
  13.     if ( !(key >= 48 && key <= 57) && key != 8 && key != 46 && key != 36 && key != 37)
  14.     {
  15.         event.returnValue = false;        
  16.     }
  17. }
  18. </script>
