About Treeview

Hello All and DriveSoft

I have found that when I use a Treeview in a project it often does not see the table (with Foreign Key ParentID) to put in the Settings.
By consulting the Forms.xml file (backup), I recover those data and inject ihem into the OnShow event of the form which contains the TV.
And it works! But this is not a normal method.
Does anyone have an explanation?

More seriously for DriveSoft:

Would it be possible for a TV to implement the DragMode (dmAutomatic) in order to allow DragAndDrop between nodes?
thanks in advance
