使用ContextMenuStrip从TreeView中删除节点(禁用选择时)

我有一个有节点的树视图。

已禁用对它的选择:

Private Sub TreeList_BeforeSelect(sender As Object, e As TreeViewCancelEventArgs) Handles TreeList.BeforeSelect
        e.Cancel = True
    End Sub

我找不到方法,无法找到哪个节点(因为将有多个)打开ContextMenuStrip(以便可以将其删除)。

根据评论,现在它可以工作了:

Dim WhichItemIsIt As TreeNode
Private Sub TreeList_NodeMouseClick(sender As Object, e As TreeNodeMouseClickEventArgs) Handles TreeList.NodeMouseClick
    WhichItemIsIt = e.Node
End Sub
Private Sub RemoveToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles RemoveToolStripMenuItem.Click
    TreeList.Nodes.Remove(WhichItemIsIt)
End Sub

我认为这会起到作用:

Private lastClickedNode As TreeNode

Private Sub TreeView1_NodeMouseClick(sender As Object, e As TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
    lastClickedNode = e.Node
End Sub

右键单击一个节点将在显示菜单之前将其分配给该字段,然后您可以从 Click 菜单项或其他的事件处理程序。
