Question

In WPF, is there an event that can be used to determine when a TabControl‘s selected tab changes?

I have tried using TabControl.SelectionChanged but it is getting fired many times when a child’s selection within a tab is changed.

You need to check the event’s source to isolate the outer-most TabControl you are looking for.

I tied this in the handler to make it work:

void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e) {     if (e.Source is TabControl)     {         // do work when tab is changed     } }
