FormClosing vs. WindowClosing: Who should go first?

Docking/MDI for Windows Forms Forum

I have event handlers for mainForm.FormClosing and dockmanager.WindowClosing.

When I close a DocumentWindow, I dispose of it. TabbedMdiWindowCloseReason = User

When I close the main form using the "X" in the upper right, DocumentWindows start closing (TabbedMdiWindowCloseReason = User) before the FormClosing event is handled and I give an "Are you sure?" message. If the user presses "Cancel", my document windows are already gone.

Is there a way to either get the mainForm.FormClosing handler to go first or to add a new TabbedMdiWindowCloseReason, Form?

Hi Anthony,

When I try in the DockForm sample, I get a TabbedMdiWindowCloseReason.Programmatic when the big parent Form's X is clicked. Can you try the latest maintenance release and let me know if you see differently?
