如何实现treeView的节点单击事件
是节点单击事件，不是选择事件，请给个思路或代码。多谢！

补充，我曾用过

C# code

treeViewTemp.MouseLeftButtonUp += new MouseButtonEventHandler(treeViewTemp_MouseLeftButtonUp);private void treeViewTemp_MouseLeftButtonUp(object sender, MouseButtonEventArgs e){MessageBox.Show("信息！");｝

C# code

RadTreeViewItem selectedItem = null;//选中时动态绑定 private void RadTreeView1_Selected(object sender, Telerik.Windows.RadRoutedEventArgs e){      RadTreeView source = sender as RadTreeView;      selectedItem = source.SelectedItem as RadTreeViewItem;      if (!selectedItem.HasItems)      {                getTreeSoapClient client = new getTreeSoapClient();                //实时险情列表                client.getSSQXListCompleted += new EventHandler<getSSQXListCompletedEventArgs>(client_getSSQXListCompleted);                client.getSSQXListAsync(selectedItem.Header.ToString().Trim());       }}
