c# - WPF中TabControl的TabChanged事件

Question

我在 WPF 中有一个 TabControl。我想找到更改选项卡时发生的事件。这个事件的名称是什么？

Answer 1

TabControl继承自 Selector其中包含 SelectionChanged event .

<TabControl SelectionChanged="OnSelectionChanged" ... />

private void OnSelectionChanged(Object sender, SelectionChangedEventArgs args)
{
    var tc = sender as TabControl; //The sender is a type of TabControl...

    if (tc != null)
    {
        var item = tc.SelectedItem;

        //Do Stuff ...
    }
}
