TabControl Undo Tab Changes

Question

I use the TabControl_SelectedIndexChanged event when the user changes tabs. TabControl.SelectedIndex / TabControl.SelectedTab returns only a new tab. Is there any way to get the previous tab? Or should I stick to the obvious preservation of the current tab every time I change tabs?

I want to use this to undo tab changes under certain conditions, for example, there are unsaved changes.

Answer 1

If you want to undo a tab change, you can use the Deselecting event. There you can undo the change by setting the Cancel property of the provided TabControlCancelEventArgs to true.

There are events that are better suited to what you want to do.
