Where to find TreeListViews ColumnHeaderClick Event?

I'm developing a tool which shows data from a database in a hierarchical manner. As there are additional data for each item I'm using a TreeListView control to display them in additional columns. The number of columns is determined by user input.

The custom control that I'm using is Ricciolos TreeListView: http://windowsclient.net/blogs/ricciolocristian/archive/2008/03/22/a-complete-wpf-treelistview-control.aspx

My problem now is, that I need to catch the ColumnHeaderClick event to apply a sorting logic. I already int开发者_StackOverflow中文版erviewed auntie Google, but no results. Maybe somene here knows where to find such an event and how to determine which column header has been clicked.

Thanks

You would need to add a handler for the GridViewColumnHeader.Click event. This post describes how to do it for the ListView, which uses the same underlying controls. This code was adapted from that link:

myTreeListView.AddHandler(GridViewColumnHeader.ClickEvent, new RoutedEventHandler(this.OnGridViewColumnHeaderClicked));

private void OnGridViewColumnHeaderClicked(object sender, RoutedEventArgs e) {
    MessageBox.Show("testing");
}

Alternatively, you can attach a handler via XAML like so:

<my:TreeListView GridViewColumnHeader.Click="OnGridViewColumnHeaderClicked" />

The e.OriginalSource will include the GridViewColumnHeader, and e.Source/sender would be the TreeListView.
