Question

我有一个带有节点的TreeView。

使用以下选项禁用选择：

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

我无法找到方法，找出哪个节点（因为会有多个节点）打开ContextMenuStrip（所以我可以用它删除它）。

根据评论，现在可行：

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

Answer 1

我认为这样可以解决问题：

Private lastClickedNode As TreeNode

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

右键单击节点会在显示菜单之前将其分配给该字段，然后您可以从菜单项的Click事件处理程序或其他任何内容访问该节点。

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