尝试处理节点上的双击事件。但是无法从事件参数/发送者获取所选文本/值(这里是Gway,Scan等..)。以下是事件处理程序代码。
private void treeView1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
object s = e.Source;
TreeView obj = (TreeView) s;
TreeViewItem item2 =(TreeViewItem)obj.SelectedItem;// item2 doesnt have any selctedText/ value property
}
请帮帮我。

因为它是树视图项,所以它下面有一棵树,所以它不仅仅是一个简单的文本,所以为了得到那些,你可以参考以下内容并使用任何适合你需要的方法
