I have 3 binded datagrid displayed on a form.
There is a parent to children to children relation between them and it works. The correct children info is displayed depending on the current row of it's parent.
The only thing is that I would like the child datagrid to be disabled if there is no parent selected. Is there a way to do that automatically?
Right now, the user can write info in a child datagrid even if there are no rows in the parent grid.
