I've seen this in several threads. The DataGridView throws quite randomly an InvalidOperationException with a message saying: "this operation could not be performed while an auto-filled column is being resized"

I sure don't understand. I don't have any column with an autosizemode and yet I get this.

I'm binding the DataGridView to a custom collection, I do have two link columns that I watch for CellContentClick in which I raise an event to a parent form that toggles another Mdi child form. The error shows up just when I try to activate another Mdi child.

Can you please give us a clear explanation on what DataGridView properties combination leads to this exception because obviously the DataGridView itself doesn't keep us in ANY WAY from making a mess...
