Hi,

I have observed an unhandled error when using datagrid.  If the following steps are performed:

  •  a range of cells is selected (using shift key) and then 
  • a copy action is triggered (Ctrl +C) and then 
  • an attempt is made to select another range of cells (using shift key), 

the following error is triggered.

I have tried a few different combinations if SelectionMode and EditMode etc. and it seemed to be a common behavior across all of the options that I checked.  If I pressed Esc to clear the clipboard, I was able to select the second range Ok.

I also note that this series of actions has worked without error in the past 6 months or so.
