How to trigger the Selected event when I select one item everytime

Question

I have a TreeView like this:

xaml:

<TreeView>
     <TreeViewItem Header="header" Name="mytreeViewItem" Selected="mytreeViewItem_Selected"/>
</TreeView>

xaml.cs:

mytreeViewItem.ItemsSource = new List<string>(){"a"};

When I select the TreeViewItem nameed a , it will trigger event mytreeViewItem_Selected . But when I select the TreeViewItem again, it wont trigger the event again. How can I trigger the Selected event when I select the TreeView every time?

Answer 1

您可以根据需要使用PreviewMouseDown事件或类似的事件（例如PreviewMouseLeftButtonDown ）。

Answer 2

Can you have

item.IsSelected = false;

in your event handler? So when you click again, the Selected event re-fires. I don't think it will fire if the same is still selected.
