主题：[求助]用代码实现的SplitContainer中，其他控件为什么看不见

解决两个问题,panel还是看不见，原因待查：

Dim split As WinForm.SplitContainer
Dim pnl As WinForm.Panel
Dim tbl As WinForm.Table
Dim but As WinForm.Button

With e.form
' 创建split分隔
  split = e.Form.CreateControl("split1", ControlTypeEnum.splitcontainer)
  split.Dock = Windows.Forms.DockStyle.Fill
  split.Orientation = windows.Forms.Orientation.horizontal
  split.splitterwidth = 4
  e.form.addcontrol(split)
  split.SplitterDistance = 500

'创建按钮
  but = e.Form.CreateControl("butadd", ControlTypeEnum.button)
  split.Panel1.AddControl(but)
  but.TopMost = True
End With

搞定：

Dim split As WinForm.SplitContainer
Dim pnl As WinForm.Panel
Dim tbl As WinForm.Table
Dim but As WinForm.Button

With e.form
    ' 创建split分隔
    split = e.Form.CreateControl("split1", ControlTypeEnum.splitcontainer)
    split.Dock = Windows.Forms.DockStyle.Fill
    split.Orientation = windows.Forms.Orientation.horizontal
    split.splitterwidth = 4
    e.form.addcontrol(split)
    split.splitterdistance =900
   
    '创建panel工具栏
    pnl = e.Form.CreateControl("pnl1", ControlTypeEnum.panel)
    pnl.SetBounds(0, 0, 400,400)
    split.panel1.AddControl(pnl)
    pnl.Topmost = True
    pnl.backcolor= Color.FromARGB(187,0,10,203)
   
    but = e.Form.CreateControl("butadd", ControlTypeEnum.button)
    split.Panel1.AddControl(but)
    but.TopMost = True
End With

这样一样可以的：

Dim split As WinForm.SplitContainer
Dim pnl As WinForm.Panel
Dim tbl As WinForm.Table
Dim but As WinForm.Button

With e.form
    ' 创建split分隔
    split = e.Form.CreateControl("split1", ControlTypeEnum.splitcontainer)
    split.Dock = Windows.Forms.DockStyle.Fill
    split.Orientation = windows.Forms.Orientation.horizontal
    split.splitterwidth = 4
    e.form.addcontrol(split)
    split.splitterdistance =900
   
    '创建panel工具栏
    pnl = e.Form.CreateControl("pnl1", ControlTypeEnum.panel)
    pnl.SetBounds(0, 0, 400,400)
    split.panel1.AddControl(pnl)
    pnl.Topmost = True
    pnl.backcolor= Color.FromARGB(187,0,10,203)
   
    but = e.Form.CreateControl("butadd", ControlTypeEnum.button)
    pnl.AddControl(but)
    but.TopMost = True
End With
