    I got it. It can be done in the following way. The key is updating the readyState flag to false in AfterExitEditModeHandler.

    //////////////////////////

    var readyState = true;

    window.onbeforeunload = checkProgressState;


    function checkProgressState(){

    if (!readyState){

    message = "WARNING: Your data is not saved, if you choose to exit your information may be lost.";

    return message;

    }

    else

    {

    readyState = true;

    }

    }

     

    function HandleExitEditMode(gridID, cellID) {

    readyState = false;

    }

     ///////////////////

    If you want this alert to be suppressed in SaveButtonClick, then OnClientClick of that button, update the readyState variable to true.

    Hey,

    I am also in the same situation. I need to prompt/save the grid data before exiting. Any clues on how to do it?

     try it, but it only worked in IE:

    <html>
    <head>
    <body  onBeforeUnLoad="clean_exit(this)"  >
    something else........

    <script language="JavaScript">  
    var changes=false;
    var problems=false;
     
    function clean_exit( src ){
          verify();  
          if (problems){
                alert ("problems: " + problems);
                // the verify routine reports problems, don't allow an exit or reloading of the page
          }else{
                // no problems, so continue
                if(changes){        
                      if (!confirm("You have made changes.  Click OK to save, or cancel to continue without saving")){
                            return false;  
                      }else{
                            //do something  
                            return true;
                      }  // end of confirm
                } // end of changes
          }// end of verify
    }

    function changed(){    
          changes=true;
    }
     
    function verify(){    
          var problems=false;
          with (Entry) {
                if (LastName.value == "") {  
                      problems=true;
                      return false;
                }
          }
          changes=false;
          return true;
    }  
    </script>
    </body>
    </html>
