How to validate cell when saving changes from Toolbar button (and focus not lost from cell)?

Hi,

I've got an UltraGrid that allows users to edit a Name field. To require a name, I have the Nullable setting for that column to Disallowed. This works fine normally, but the Save button is in a toolbar ribbon, so it doesn't actually pull focus away from the cell when clicked (thus allowing an empty string in the column that throws an error on UpdateData()).

I've tried doing a PerformAction(ExitEditMode) at the start of the Save code, and it correctly fires the validation, but then proceeds with the rest of the Save code.

Is there an easy way for me to validate, cancel the Save, and retain focus on the bad cell?

Thanks,
J

Hi J,
Doesn't PerformAction return a boolean which indicates if the action was successful? If so, you could just skip the rest of the code if the PerformAction fails.
If I am wrong and there is no such return value, then you could check to see if the grid is still in edit mode after you call PerformAction. If so, you know the PerformAction failed and again, you can skip the rest of the code.

Mike,

I apologize for not putting more information about PerformAction--it returns true because the action successfully happened. Then it proceeds with the save code.

Your other suggestion, however, has proven fruitful: I call grid.PerformAction(UltraGridAction.ExitEditMode), then query the grid to see if it's in edit mode. I do that with this line:

if ((grid.CurrentState & UltraGridState.InEdit) == UltraGridState.InEdit) ...

Is that the best code to test this condition?

Now I have another question: when a cell button is clicked on the row, I put the same condition in to test if the cell value is no good and then return. BUT, if it was the Delete button that was clicked (and only the Delete button), I still want to do delete the row. However, I get the validation message before I get to the ClickCellButton code where I can check if the grid's in the edit state and then return if it is. (If it's the delete button, I can still delete the row, but the user would have gotten the message box about the bad value, which I don't want to do.) Any ideas here?

Thanks again,
J
