I have 2 separate tabcontrols, currently with 4 tabs in each control. I would like to be able to change the selected tab in the second tabcontrol based on the selected tab in the first. The current use case is that if the second item in the first tab control is selected, the 4th item in the second tabcontrol would become the selected tab. Can you provide an example of how to do this, all in XAML preferably? I was thinking a trigger should do it, but I can't figure out how to bind the controls.
