How to programmatically select a TabItem in WPF TabControl

Question

I would like to know how to select a specific TabItem in a WPF TabControl.

I tried these bellow but nothing work!

MyTabControl.SelectedIndex = x

MyTabControl.SelectedItem = MyTabItem

MyTabControl.SelectedValue = MyTabItem

MyTabItem.IsSelected = True

Answer 1

As @Chris says, any of the first three things should work and as @Phyxx says, it doesn't always really work. The problem is some subtle thing about the order of property changes. To work around it you need to let the WPF invoke your tab-selection code in its own time:

Dispatcher.BeginInvoke((Action)(() => MyTabControl.SelectedIndex = x));

This does just what Phyxx' timer does, but in a slightly less extreme way.

Answer 2

All your examples except the third one are correct and will work. The problem must be at another location. Maybe you reset the item after setting or your code never is called?

Valid

MyTabControl.SelectedIndex = x   
MyTabControl.SelectedItem = MyTabItem    
MyTabItem.IsSelected = True 

Invalid

MyTabControl.SelectedValue = MyTabItem 

Answer 3

Loop through the TabItems and for the tab to be selected, set

tabItem.IsSelected = true

If there are any other place due to binding changing you will see problem. Otherwise, the above code should work.
