You already help me with implementation of Cancel-button functionality. It works if the user pressed Cancel, when the cell is currently editing has focus and caret.
But, after user try to press OK button with the incompleted row, exception window shows and current cell lost focus. Errorprovider appear, but without focus on the cell.
In this state CancelEdit doesn''t work. Further validation failed and form won''t close by Cancel.
Please help me with this state of window.]
