我在运行时创建上下文菜单取决于 datagridview 选定单元格中的文本。
像这样:
With ContextMenuStrip1
.Items.Clear()
Dim Str As String = DataGridView1.Item(1, DataGridView1.CurrentRow.Index).Value
Dim strArr() As String = Str.Split(" ")
For count As Integer = 0 To strArr.Length - 1
If strArr(count).Length > 1 Then
.Items.Add(strArr(count))
End If
Next
.Items.Add("-")
.Items.Add("Common operation ...")
.Items.Add("Second common operation ...")
AddHandler .Click, AddressOf cMenu_Click
.Show(New Point(Cursor.Position.X, Cursor.Position.Y))
End With
etc...
然后我添加这样的事件处理程序:
Private Sub cMenu_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim mytext As String
mytext = (CType(sender, ContextMenuStrip).Text)
Debug.Print(mytext)
'after all...
RemoveHandler ContextMenuStrip1.Click, AddressOf cMenu_Click
End Sub
作为使用此代码的 vbnet 初学者,我无法在事件处理程序中获取已触发菜单项的文本。
所以请帮助获取它。
