查找节点下的上下文菜单中点击 [英] Find node clicked under context menu

问题描述

我怎样才能找出哪个节点在树列表中的上下文菜单已被激活？例如右键单击一个节点，并从菜单中选择一个选项。

How can I find out which node in a tree list the context menu has been activated? For instance right-clicking a node and selecting an option from the menu.

我不能使用的TreeView， SelectedNode 属性，因为节点仅获右键点击并没有被选中。

I can't use the TreeViews' SelectedNode property because the node is only been right-clicked and not selected.

推荐答案

您可以用鼠标点击事件添加到TreeView，然后使用GetNodeAt给出的鼠标坐标由MouseEventArgs提供选择正确的节点。

You can add a mouse click event to the TreeView, then select the correct node using GetNodeAt given the mouse coordinates provided by the MouseEventArgs.

void treeView1MouseUp(object sender, MouseEventArgs e)
{
    if(e.Button == MouseButtons.Right)
    {
        // Select the clicked node
        treeView1.SelectedNode = treeView1.GetNodeAt(e.X, e.Y);

        if(treeView1.SelectedNode != null)
        {
            myContextMenuStrip.Show(treeView1, e.Location);
        }
    }
}
