主题：为什么anchor不起作用

    ctl = e.Form.CreateControl("LineRH" & e.form.controls("LineRH_number").text, ControlTypeEnum.line)
    ctl.ThickNess = 4
    ctl.LineColor = Color.SteelBlue
    ctl.width = 60
    ctl.Height = 4
    ctl.anchor = Windows.Forms.AnchorStyles.Top Or Windows.Forms.AnchorStyles.Right

If ctl IsNot Nothing Then
    Dim body As object = e.Form.controls("pnl_body")
   
    ctl.Left = 100
    ctl.Top = 100
   
    body.AddControl(ctl)
End If

上述代码没有起到右端锚定的作用，请指教

 

ctl.right执行后也提示没有right这个属性
