I have a DGV with a few custom combo box columns.
I use the row header click event to put the custom columns into an edit state.
Since 2.02.24 the row leave event fires when you click on a custom combo box drop down.
As I use the Row Leave event to reset the row edit state, this has the effect of cancelling the row edit.
Interestingly if I click on a Custom Combo Box in the edit state as if I was going to type a search value,
this has the effect of preventing the row leave event from miss firing, not only for that row but for any other row subsequently selected to edit.
Frank has an example
Thanks for your help
