I am having an issue with the grid. I am using GridEditMode.PopUp. If I click create to open the PopUp and then press cancel, it inserts a blank row into the grid
I tried to replicate the behavior with our online Popup editing example, however, I was not able to. When I click cancel the new row is removed on my end.
Would you send us a runnable project where the behavior is replicated? This will enable us to examine the behavior locally and look for its cause.
