Hello,

I have below code with OnDataRecordPresenterContextMenuOpening that attach contextMenu to the grid and  ExportExecuted is the command handler.

When ExportExecuted is invoked, I was expecting the sender of it to be XamDataGrid instance (as I do exportMenuItem.CommandTarget = grid), instead I am getting the sender as my window instance,

Any idea what I am doing wrong here? Thanks in advance.

            EventManager.RegisterClassHandler(typeof(DataRecordPresenter),
                DataRecordPresenter.ContextMenuOpeningEvent, new ContextMenuEventHandler(OnDataRecordPresenterContextMenuOpening));

            this.CommandBindings.Add(new CommandBinding(_exportCommand, ExportExecuted, ExportCanExecute));

        public void OnDataRecordPresenterContextMenuOpening(object sender, ContextMenuEventArgs e)
        {
            var grid = (sender as DataRecordPresenter).DataPresenter as XamDataGrid;

            if (grid.ContextMenu == null)
            {
                MenuItem exportMenuItem = new MenuItem { Header = "_Export", Name = "mnuExport", Command = _exportCommand };
                exportMenuItem.CommandParameter = grid;
                exportMenuItem.CommandTarget = grid;
                ContextMenu gridContextMenu = new ContextMenu();
                gridContextMenu.Items.Add(exportMenuItem);
                grid.ContextMenu = gridContextMenu;
            }
        }

        void ExportExecuted(object sender, ExecutedRoutedEventArgs e)
        {

            var grid = sender as XamDataGrid;. // Why this is NULL?

        }
