<asp:panel id="pnlInfo" runat="server" style="display:none" cssclass=" ui-dialog ui-widget ui-widget-content ui-corner-all  ui-draggable ui-resizable colored-popup" xmlns:asp="#unknown">
<div id="div1" runat="server">
    <span>Message</span><a id="A2" class="ui-dialog-titlebar-close ui-corner-all" role="button"><span></span></a></div>
 <br />
 <table>
 <tr>
 <td align="center">
 <asp:label id="lblInfo" runat="server" text=""></asp:label>
 </td>
 </tr>
 <tr>
 <td align="center">
  <asp:button id="btnOK" runat="server" text="OK" cssclass="blue-button-thirty-three" onclientclick=" return HidePopup();" />

Thanks to every one...

I got the answer..

Button Click server side event:

ScriptManager.RegisterStartupScript(this, this.GetType(), "ModalPopup", "Sys.Application.add_load(  function()  
{    
    reloadModal = function() {
    funOpenUploadImageController();
};    
    Sys.Application.add_init(reloadModal); 
} 
);", true);

then i got the modalpopupextender id in javascript

Thanks
