右鍵單擊時動態創建項目的文本

Question

我有一些動態創建帶有上下文菜單條的標籤。當您右鍵單擊標籤時，會爲您提供上下文菜單條。如何在單擊上下文菜單條中的項目時獲取文本？我知道這是一個非常簡單的問題，但我需要一些幫助。 我試過

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

我試圖讓產生的ContextMenuStrip標籤的文本。

Answer 1

我認爲你正在尋找該控件激發上下文菜單中，這樣的事情：

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 

轉換爲VB.Net從Determine what control the ContextMenuStrip was used on
