如何右键单击树视图控件中选择节点

发布于 2024-12-02 19:03:45 字数 66 浏览 0 评论 0原文

为什么我右键单击树视图中的节点，焦点会移至该节点，然后立即返回到先前选择的节点。有什么方法可以允许右键单击选择节点吗？

这是因为突出显示颜色执行两个职责，它显示选定的节点和显示聚焦的节点。如果您不对右键单击事件执行任何操作，则会跳回到所选节点。解决方法是选择节点：

    private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e) {
        if (e.Button == MouseButtons.Right) treeView1.SelectedNode = e.Node;
    }

加上您想要执行的任何其他操作，通常显示上下文菜单。

That's because the highlight color performs two duties, it shows the selected node and shows the focused node. If you don't do anything with the right-click event then it jumps back to the selected node. The workaround is to select the node:

    private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e) {
        if (e.Button == MouseButtons.Right) treeView1.SelectedNode = e.Node;
    }

Plus anything else you want to do, usually displaying a context menu.

抱歉，我有点操之过急，我发现如何做到这一点如下：

    Private Sub TreeView1_NodeMouseClick(sender As Object, e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
        If e.Button = Windows.Forms.MouseButtons.Right Then
            TreeView1.SelectedNode = e.Node
        End If
    End Sub

控件不应该按照标准执行此操作吗？

Apologies I jumped the gun slightly I found how to do this as follows:

    Private Sub TreeView1_NodeMouseClick(sender As Object, e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
        If e.Button = Windows.Forms.MouseButtons.Right Then
            TreeView1.SelectedNode = e.Node
        End If
    End Sub

Shouldn't the control do this as standard though?
