问题
I'm pretty new to WPF and I'm working on a small C# application that has a WPF TabControl with 4 tabs. I'm doing some minor things in each tab when the tab loads (loading combo box values, etc.) but I'm having a problem with the 4th tab not firing the Loaded event.I've verified that the position is the problem by switching the order around among the four tabs. Whatever tab is in the last position will not fire the Loaded event, whatever tabs are in the first three positions are working fine. I'm at a loss at this point. Suggestions?
