How to show progress ring?

[R Brian Lindahl]

I'm using row drag & drop that involves a server-side call that can take 15-20 seconds. I'd like to show the progress ring as if the grid is loading new data so that the customer will not think that the app is just stuck. Is it possible to do this? I'm picturing a call to show & hide the ring at the beginning & end of the javascript function that calls the server-side code.

Hi Brian, 

We suspect that your requirement is to show/hide waitingpopup control when triggering a server side call and updating the grid dataSource.  

<script type="text/javascript"> 

 

    //click event of button 

    function getData(e) { 

        $("#Grid").ejWaitingPopup("show");//show the waitingpopup control before ajax call 

        $.ajax({ 

            url: "/Home/GetData", 

            type: "POST", 

            dataType: 'json', 

            contentType: "application/json; charset=utf-8", 

            success: function (data) { 

                $("#Grid").ejGrid({ dataSource: data.d.data }); 

                $("#Grid").ejWaitingPopup("hide");//hide the control after binding data to grid 

            } 

        }); 

    } 

 

    </script>

Actually, I mis-stated the objective just slightly. Yes, the waitingpopup is what I'm looking for... however, in this case it's not a javascript call... I was remembering the wrong handler. In this case, I'm using

.RowDropSettings(drop => drop.RowDropMapper("/Products/RowDropHandler"))
   
Is there a way to turn on the waitingpopup during the rowmapper call? Is there a way to handle the row drop in javascript so that I can add the call as you described?

Hi Brian, 

Yes. We do have ejGrid client side events “rowDrop” and “beforeRowDrop” which will be triggered upon dropping rows in grid. Please refer to the below documentation for more information.
