    Hello vasiharan,

     

    I have been looking into your code and I believe that this code snippet will work only during a full postback or if the control is inside UpdatePanel. In the case of  updating- WebDataGrid makes async call to the server in order to commit its changes therefore your alert won’t pop up as expected.

     

    However If your WebDataGrid is placed inside of UpdatePanel you can just set the EnableAjax property of the WebDataGrid to false and then show the message like this:

        void WebDataGrid1_RowUpdating(object sender, Infragistics.Web.UI.GridControls.RowUpdatingEventArgs e)

        {

     

            String Message = "daaa";

     

            ScriptManager.RegisterStartupScript(updatePanel1, updatePanel1.GetType(), "Alerts", "alert('" + Message.ToString() + "')", true);     

      

        }

     

    Please let me know if this helps.
