I have an ultragrid in edit mode.
I want that the grid validates changes of the active row when a user tries to move the mouse to another row (event without clicking). How could this be achieved?
There are a number of ways to do this.
You could handle the BeforeRowUpdate event.You may also want to set the RowUpdateCancelAction property on the grid to determine what happens when you set e.Cancel to true in BeforeRowUpdate.
Or you could use BeforeCellUpdate or BeforeCellDeactivate if you want more fine control of the validation of each cell.
