在 WPF TreeView 中的单击事件上获取所选子节点的值 [英] Getting the value of the Selected Child Nodes on click Event in WPF TreeView

问题描述

我在 WPF 中有一个 TreeView，它包含一个主节点和 5 个子节点.一旦主节点展开，我们就会得到子节点.现在在展开子节点时，我们会得到一些值.这是我在 WPF 中的 treeView 的表示.在这个中，我想获取已扩展的 5 个子节点之一的值.

I have a TreeView in WPF Which contains One Main Node and 5 Child Node.As soon as Main Node is expanded we get child Nodes.Now on Expanding child node we get some Values.This is the representation of my treeView In WPF.In this one i want to get the Value of one of the 5 Child Node that has been expanded.

这是我正在尝试的代码..

Here is the code that i am trying ..

void getTreeView()
{

    TreeViewItem treeItem = null;
    treeItem = new TreeViewItem();
    treeItem.Header = "Name";
    treeItem.MouseLeftButtonUp += treeItem_MouseLeftButtonUp;
}

void treeItem_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
   TreeViewItem item = sender as TreeViewItem;
   foreach(TreeViewItem child in item.Items) { 

       string childNode=child.Header as string;


 }
}

但是在 childNode 中，我得到了所有 5 个子节点的值，而我需要选择的值.

But here in childNode i am getting the value of the all 5 child node whereas i need to that of the selected ones.

请帮帮我

推荐答案

如果您只想获取选定的节点，请检查 TreeViewItem 的 IsSelected 属性，如下所示:

If you want to get only selected node, check for IsSelected property of TreeViewItem like this:

foreach(TreeViewItem child in item.Items) 
{ 
   if(child.IsSelected)
   {
      string childNode= child.Header.ToString();
   }
}
