如何滚动时消除闪烁Windows.Forms的中自定义的控制？ [英] How to eliminate flicker in Windows.Forms custom control when scrolling?

问题描述

我要创建在C＃中的自定义控制。但每次我都完全重绘我的控制，它闪烁，即使我使用双缓冲（画上一个形象第一，和块传输的）。

I want to create a custom control in C#. But every time I have to fully redraw my control, it flickers, even if I use double buffering (drawing to an Image first, and blitting that).

我如何消除闪烁时，我有完全重绘？

How do I eliminate flicker when I have to fully redraw?

推荐答案

您可以尝试把在InitiliseComponent通话后你的构造如下。

You could try putting the following in your constructor after the InitiliseComponent call.

SetStyle(ControlStyles.OptimizedDoubleBuffer | 
         ControlStyles.UserPaint |
         ControlStyles.AllPaintingInWmPaint, true);

编辑：

如果你给这个一展身手，如果可以，删除自己的双缓冲code，只是有控制绘制自身应对被称为相应的虚拟方法。

If you're giving this a go, if you can, remove your own double buffering code and just have the control draw itself in response to the appropriate virtual methods being called.
