//----- Note: -----------------Prashant Kumar
// (1) To display ajax loading, you have to include this js file in your aspx file and script manager also.
// (2) <div id="updateProgressDiv" class="updateProgress" style="display:none;z-index:999999;">
//      <div align="center" class="Progress"><img  alt="" src="../images/loading1.gif" align="absmiddle" /> Loading...</div>
//     </div>
// (3) Put above code just before closing form tag.
// (4) Add update panel in your form as well.
// (5) EnablePartialRendering="true"  ScriptMode="Release" <-- include this code in script manager also.
