TreeView中的HoverSelection（C＃） [英] HoverSelection in TreeView (C#)

问题描述

在TreeView控件中，鼠标右键单击DOES选择指定的节点。但是，顶级节点以海军突出显示，而不是实际选择的节点。如果选择了节点，则首先通过鼠标左键单击，该节点将以正确的方式突出显示为海军。
我的问题是如何在TreeView控件中实现HoverSelection。不幸的是，我找不到"HoverSelection"。属性中的选项。

In a TreeView control, a mouse Right click DOES select the specified node. However, the top node is highlighted in navy, instead of the actually selected node. If the node is selected, first by a mouse Left click, the node is highlighted in navy properly. My question is how to implement a HoverSelection in TreeView control. Unfortunately I can't find a "HoverSelection" option in the properties.

谢谢

推荐答案

您好，

 

只需为NodeMouseHover事件注册TreeView并执行以下操作：

Just register the TreeView for the NodeMouseHover event and do this:

    private void treeView1_NodeMouseHover(object sender, TreeNodeMouseHoverEventArgs e)
    {
      treeView1.SelectedNode = e.Node;
    }
