Exporting data from jqgrid to excel sheet

Question

Hi i want to export the data present in my jQgrid in one of my asp.net web application into excel sheet i looked around the net and i find only sites that tell me how to do it for MVC application and this is not wat i want. I tried doing this but i am getting some error in my global.asax file.
i added a button in my web page and on click of it i am doing this.

 protected void btnExport_Click(object sender, EventArgs e)
    {            
        grdLateFeeConfiguration.ExportToExcel("BlockedUsers.xls");
    }

and i get an exception here in my global.asax file

 protected void Application_Error(object sender, EventArgs e)
    {
        Exception exception = Server.GetLastError();
        HttpException httpException = (HttpException)exception;
        int httpCode = httpException.GetHttpCode();
        Application["errorInfor"] = httpCode;

    }

The exception object that is returned by the Server.GetLasrError() method is always null and i get a null pointer exception when httpException.GetHttpCode(); i dont understand wat is happening can someone explain wat is happening.

This problem was occurring due to the presence of UpdatePannel control when this was removed it worked fine.
