I have a RadGrid in batch edit mode, cell edit.  I'm using the events 'OnBatchEditOpened' to manipulate some of the UI before the user gets to see/use it and then 'BatchEditCellValueChanged' to run further logic.

I have a pair of cells in the grid, in column X, that need to be the opposite of each other's selections in the rad comboBox I'm using in the editor.  If one cell has optionA selected in row A then the other cell needs to show optionB in row B.  The issue I'm running into is that to change cell values I have been using this method:

    batchManager.changeCellValue(cellToChange, valueToUse).

This works fine...normally when I'm updating values in some OTHER grid.  But when I run this logic from the 'BatchEditCellValueChanged' method of the SAME GRID then the grid gets a bit wonky.  I already have code to avoid recursive looping.  The problem is that the grid has a set of functions that are fired in a set sequence, like opening, opened, changing, changed, closing, closed, etc.  When you cause that data flow to step INTO itself before the first is finished... it winds up leaving the edit control visible in the starting cell.

So - CellA opens in editor, I select the radComboBox option A and tab out of the cell.  This causes Telerik's event chain to start firing... it gets to 'BatchEditCellValueChanged' and runs my code.  My code then tell the SAME grid to update CellB in the other row... and that starts the grid's event chain to START OVER... before CellA's 'value changed' event is finished.  I think this is what is causing the logic issues and is making the editor, i.e. the radComboBox in CellA, to remain visible even after I exit the cell.

So - all that being said.  What is the 'correct' way to change cellB's in row B when cellA's value changes in rowA of the same batch edit grid?

I am attempting to place a confirm delete prompt message on a RadButton in a GridTemplateColumn.  Depending on the browser, I am getting mixed results, none of which are acceptable.

In Edge and Chrome, Pressing the delete button pops the message up, but pressing Ok or Cancel will pop the message up second time immedately, and pressing Ok or Cancel on the second message will perform the action desired (Cancel will close message and do nothing, Ok will fire DeleteCommand on server side)

In IE11, pressing the Ok or Cancel will show the confirm message only once.  Ok will run the DeleteCommand routine as expected.  However, Cancel will ignore the cancel and ALSO run the DeleteCommand routine.  

My guess is whatever is causing the issue to show a double-message in Edge or Chrome is being ignored in IE and it just fires the delete command regardless of what button was pressed on the confirm message.

Here are some code snippets:

I have RadGrid with EditMode="Batch". I have two columns Location and Department  and comboboxes Location and Department inside  EditItemTemplate and InsertItemTemplate. They use SqlDataSource, Location data source just query all the location records, department  data source has parameter - location id.

I need to be able to update data source of Department in edit and insert mode  depending on what is  selected in the column "location". I created hidden control that is used by department data source, but can't figure out when and how to set it to rebind the Department combobox.

Any help is greatly appreciated!
