主题：同一窗口中的两个容器能不能同时添加同一个控件？？

Dim box As WinForm.GroupBox = e.Form.Controls("GroupBox1整表")

Dim Rowedit As WinForm.GroupBox = e.Form.Controls("GroupBox1整行")

 For i As Integer = 0 To djs.Length -1

        Dim btn As WinForm.Button

        btn = e.Form.CreateControl(djs(i),ControlTypeEnum.Button)

        btn.Text = djs(i)

        btn.Left = L

        btn.Top = t

        l = l + (w-(i+2)*10)/djs.Length

    Next
