Combo only for leaf node

Hi all,

I have a comboEdit that the user can use to set a value for a cell.

How can I force that this edit mask (the combobox) appears only for leaf node, and not for the parent ("Sezione" in figure)?

Thanks in advance.

Hi Luigi,

You will want to check the TreeList.ShowingEditor Event, it has a CancelEventArgs.

Regards,

Thank you Marc,

and how can I set the number of items that appear when I open the combo? (now it's 7).

Are you looking for the DropDownRows property?
