The issue you are seeing is probably caused by the inability of the engine
to delete the object that is the target of the current event. When you
replace the data grid contents during selectionChanged you are trying to
delete the control that was clicked on and trigger the selectionChanged
message. The engine doesn’t like that. You will need to use `send in time`
to accomplish what you are after.
