We are getting a problem with grid functionality after upgrading from 2.25 to 2.26. I have attached a test project. To see the problem:
We did not have this problem before version 2.26.
Just another note on this.
It appears that the presence of the checkbox columns causes the problem. Removing the checkbox columns causes the grid to work fine. Just having one checkbox template column in the grid causes the strange crash behavior in 2.26. Before 2.26, we had no problems with the checkbox templates impacting behavior.
