油漆事件 [英] Paint event

问题描述

我正在创建一个用户控件，它从

UserControl_Paint事件中执行了很多自己的绘制操作，主要使用的是'

传入的e.Graphics对象油漆事件。它工作得很好。


偶尔，油漆事件不会发生。当用户按下Alt键第一个

时间时，这主要发生在具有许多第三方控件的应用程序

中。第一次按键后问题不会发生。我无法确定

来确定问题的来源。


欢迎任何和所有想法，因为我在最后绳子。


谢谢。

尝试使用onpaint覆盖。

I am creating a User Control that does a lot of it own painting from the
UserControl_Paint event mostly using the e.Graphics object that''s
passed into Paint event. It works pretty good.

Occasionally, the paint event doesn''t fire. This occurs mostly in apps
with many 3rd party controls when the user presses Alt key the first
time. The problem doesn''t occur after the 1st key press. I can''t seem
to nail down where the problem is coming from.

Any and all ideas are welcome, as I am at the end of the rope.

Thanks.

Try the onpaint override instead.
