如何创建自定义单选按钮C#Compact Framework 3.5 [英] How to create custom radiobutton c# compact framework 3.5

问题描述

我试图找到一些现成的代码，但是失败了.如果有人解释创建过程，对我来说就足够了.

I tried to find some ready code, but I failed. it would be enough for me, if someone explain the process of creatiojn. Is radiobutton merged two controls or just a modified label?

推荐答案

WinForms单选按钮是Windows的标准控件，因此很难对它们进行小的扩展.

单选按钮，按钮和文本一起是一个控件.如果要更改其外观，可以覆盖OnPaint，但需要同时绘制两个部分.

我在此处找到了一个示例[ ^ ].

WinForms radio buttons are standard Windows controls, and therefore it''s quite difficult to perform small extensions on them.

A radio button, button and text together, is one control. If you want to change its appearance, you can override OnPaint, but you need to draw both parts.

I found an example here[^].

由于Bob正确指出的原因，正确的解决方案如下:

创建您自己的单选按钮控件，这是一个完全自定义的按钮控件.从System.Windows.Forms.Control派生您的类，根据状态等覆盖OnPaint来呈现其外观.在状态更改或影响控件外观的任何其他属性上使用System.Windows.Forms.Control.Invalidate.

使用System.Windows.Forms，这是非常简单的任务.

By the reasons Bob correctly pointed out, right solution would be the following:

Create your own radio button control, a completely custom one. Derive your class right from System.Windows.Forms.Control, override OnPaint to render its appearance depending on states, etc. Use System.Windows.Forms.Control.Invalidate on the change of state or any other properties affecting control appearance.

With System.Windows.Forms, this is pretty simple task.
