如何在设计时间内看到自定义控件属性的变化

问题描述：

我有一个带有自定义属性bordercolor的自定义标签控件。
在VS2010的de属性窗口中的
你可以更改标签的bordercolor

自定义标签覆盖了onPaint活动

I have a custom label control with a custom property bordercolor.
in de property window of VS2010 you can change the bordercolor of the label
The custom label overrides the onPaint event

Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)

     MyBase.OnPaint(e)

     ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, _BorderColor, 1, _
         ButtonBorderStyle.Solid, _BorderColor, 1, ButtonBorderStyle.Solid, _BorderColor, 1, _
         ButtonBorderStyle.Solid, _BorderColor, 1, ButtonBorderStyle.Solid)

 End Sub

如果改变边框颜色VS2010并不会无变化地改变颜色形式类似于标签的标准backcolor属性。我首先要点击表单查看我所做的更改。

我怎样才能在VS2010的设计模式中看到变化

If a change the bordercolor VS2010 does not immidiatly change the color on the form like the standard backcolor property of the label. I first have to click on the form to see the change i've made.

How can i see the changes immidiatly in design mode in VS2010

答

在自定义属性设置器中，调用控件上的Invalidate（）方法。

In the custom property setter, call the Invalidate() method on the control.

对于designTime，您必须重建控件以刷新它在设计师。

For designTime you have to rebuild the control to refresh it in the designer.
