TreeView节点被突出显示，即使我没有右键单击节点

本文介绍了TreeView节点被突出显示，即使我没有右键单击节点的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在一个winform和我的用户界面的工作有一个TreeView，我发现树节点将被突出显示，即使我没有点击右键鼠标（例如，当我点击下面的节点1将突出显示的节点上位置），但我真的不因为我想表现出不同的上下文菜单的时候我没有上一个TreeNode点击喜欢这种行为

+的RootNode

| _节点1 [右键点击这里，节点1将突出显示] | | _节点2 [右键点击这里，节点2将被突出显示]

解决方案

我已经找到另一种方法来防止节点成为亮点，当用户未在节点上单击，我只加时设置的背景色和前景色为每个节点它树

newNode.BackColor = treeview1.BackColor; newNode.ForeColor = treeview1.ForeColor; treeview1.Nodes.Add（newNode）;

然后在MouseDown事件中，设置SelectedNode属性如下

私人无效treeView1_MouseDown（对象发件人，MouseEventArgs E） {树节点节点= treeView1.GetNodeAt（e.Location）; 如果（节点= NULL&放大器;！&安培; Node.Bounds.Contains（e.Location）） treeView1.SelectedNode =节点; ，否则 treeView1.SelectedNode = NULL; }

I am working on a winform and on my UI there is a treeview, I found that the treenode will be highlighted even I did not click on the node by right mouse (eg, Node1 will be highlighted when I click on the following position), but i really do not like this behavior because I want to show a different context menu when I did not click on a treenode

+RootNode

|_ Node1 [ Right Click Here, Node1 will be highlighted] | |_ Node2 [ Right Click Here, Node2 will be highlighted]

解决方案

I have found another method to prevent the node to be highlight when the user not click on the node, and I only set the BackColor and ForeColor for each of the node when adding it to the tree

newNode.BackColor = treeview1.BackColor; newNode.ForeColor = treeview1.ForeColor; treeview1.Nodes.Add(newNode);

Then in the MouseDown event, set the SelectedNode property as following

private void treeView1_MouseDown(object sender, MouseEventArgs e) { TreeNode Node = treeView1.GetNodeAt(e.Location); if (Node != null && Node.Bounds.Contains(e.Location)) treeView1.SelectedNode = Node; else treeView1.SelectedNode = null; }
