右键单击时动态创建项目的文本

Question

我有一些动态创建带有上下文菜单条的标签。当您右键单击标签时，会为您提供上下文菜单条。如何在单击上下文菜单条中的项目时获取文本？我知道这是一个非常简单的问题，但我需要一些帮助。 我试过

Private Sub DeleteToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DeleteToolStripMenuItem.Click 
     MsgBox(sender.Text) 
End Sub 

我试图让产生的ContextMenuStrip标签的文本。

我认为你正在寻找该控件激发上下文菜单中，这样的事情：

Private Sub DeleteToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles DeleteToolStripMenuItem.Click 

    Dim menuItem As ToolStripItem = TryCast(sender, ToolStripItem) 
    If menuItem IsNot Nothing Then 
    Dim owner As ContextMenuStrip = TryCast(menuItem.Owner, ContextMenuStrip) 
    If owner IsNot Nothing Then 
     Dim sourceControl As Control = owner.SourceControl 
     MessageBox.Show(sourceControl.Text) 
    End If 
    End If 
End Sub
