I'm currently using a RadGrid with EditMode=Batch. I need a client-side notification of changes to the grid to do some screen updates. For Update and Insert changes I'm listening to the OnBatchEditCellValueChanged event, and that's working fine.

How can I get a client-side notification of a row being deleted by the user? The grid currently has a Delete Button column (GridButtonColumn with a CommandName of Delete) which the user is clicking, but I'm open to other solutions. When the user clicks the button, the row is actually deleted from the screen and the delete is sent to the server as part of a Save Changes. The only part that's missing is a client-side notification.

I've tried the obvious choices of OnRowDeleting, OnRowDeleted, OnRowDestroying, and OnRowDropped, but none of those seem to work with BatchEdit. I think that I need something like OnBatchEditRowDeleted, but that doesn't exist.

Any ideas on how to make BatchEdit and RowDelete play nice with each other and generate a client-side event?

Thanks,
DaveL

Hi Dave,

Thank you for contacting us.

Our developers are planning to include this kind of event for the future releases, but I'm not able to give any additional details whether it will be a new event or one of the existing grid delete handlers.

You can use the following approach for the time being:

Telerik.Web.UI.GridBatchEditing.prototype.original_deleteRecord =

Telerik.Web.UI.GridBatchEditing.prototype.deleteRecord;

Telerik.Web.UI.GridBatchEditing.prototype.deleteRecord = function (t, r) {

myHandlerName(this.get_owner());

this.original_deleteRecord(t, r);

}

function myHandlerName(grid) {

alert("Record will be deleted from grid: " + grid.get_id());

}

Hope this helps. Please give it a try and let me know if it works for you.

Regards,
Eyup
