I need to access TabPage before removing TabControl

I need to access TabPage before removing TabControl

In main program I add TabPage (UserControl) to TabControl. This Control
has few data I would like to have before removing it. When using
TabControl.RemoveControl the sender is TabControl, and I cannot access the
TabPage because I don't know which one is it (using
TabControl.TabPages.Count I know that my Tab ain't remove yet so I can
access it).
Is there any Event for TabControl to mark TabPage that is going to be
removed? or any other idea.
Basically: I add tabpage with editing of some MySql data, and after
closing i would like check is there was a Edit on that row (via bool
wasEdited) and if it was edited i would like to read the id of that row.
If the form for editing wasn't in seperate file i would just run method on
that, and I can't use static method to access non static DataGridView to
update row.
