WPF Tab Control: How do I get the currently selected tab?

问题

In my tab SelectionChanged event (is this the correct event, I can't find a tab changed event?), how do I access the new tab?

Also from outside this event in normal code, how do I access the currently selected tab?

  TabControl.SelectionChanged += new System.Windows.Controls.SelectionChangedEventHandler(TabControl_SelectionChanged);

  void TabControl_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
  {
      //How so access my currently selected tab???
  }

回答1:

TabControl.SelectedItem is the selected tab.

cast it to a TabItem to get the properties.

What I mostly do is bind it to a viewmodel.

回答2:

you can use the TabControl.SelectedItem property, it will get you the selected TabItem

Sample shown below

TabItem ti = Tabs1.SelectedItem as TabItem;
MessageBox.Show("This is " + ti.Header + " tab");

回答3:

TabControl.SelectedIndex gets you the currently selected tab index in version 3.0 and later of the .NET Framework.
