Hello,
I had a crash of the ultra win grid in the following case, using UltraWinGrid v11.1 (version : 11.1.20111.2076).
In the case of a group by row setup, I tried to select multiple cells (as you can see on the following screenshort, I clicked on the cell containing F and then I moved my mouse towards G, H, then it crashed when i tried to reach A).
Attached with this message you can find the source code to reproduce this error (you just have to select column "Value" for the group by, and then select multiple cells.
Is it a known issue and is there any workaround ? Working with v12 grid is not on option for me.
Thanks by advance

Hello Christophe,
Thank you for contacting Infragistics Developer support.
We are aware of this issue and it has been fixed in 11.2 and higher. If you are unable to upgrade to a newer version (which is the recommended option) there are a few workarounds I managed to discover. You could set the CellClickAction to be RowSelect instead of CellSelect. Alternatively you could implement ISelectionStrategyFilter. This interface allows you to change the way that the UltraGrid selection is done. In this case I have put a try-catch method around the place where the exception occurs. For more information about the interface visit this link:
http://help.infragistics.com/Doc/WinForms/2013.2/CLR4.0/?page=Infragistics4.Win.UltraWinGrid.v13.2~Infragistics.Win.UltraWinGrid.UltraGrid~SelectionStrategyFilter.html
I have modified your sample in order to demonstrate the ISelectionStrategyFilter approach.
Please let me know if you have any additional questions.
Thanks, i will try the selectionstrategy approach.
