I am using Grid with Cell Selection enabled and DragToSelect="true". If I define a Template inside the GridColumn tag and I add a div inside that, SelectedCellsChanged event handler does not trigger if I start dragging by clicking on the div or if I drop inside that one.

The only workaround for the time being is to disable the drag selection and let the user only select cells by clicking them. The cells will be selected even if the user clicks on the custom <div> element inside the template.
