推荐答案
您需要这样的内容:-
You need something like this:-
<pre>
Function LookForControl(ByVal controlName As String) As Control
Dim x As Control = Nothing
For Each ctl As Control In Me.Controls
If ctl.Name = controlName Then
x = ctl
Return ctl
ElseIf ctl.HasChildren Then
x = LookForControl(controlName)
End If
If x IsNot Nothing Then
Return x
End If
Next
Return Nothing
End Function
1不要忘记为控件命名
2为其唯一命名
1 dont forget to name your controls
2 name them uniquely
