翻译 maninwest@Codeforge作者:Tanna@CodeProject网络上可以找到渐变控件，但是没有找到可以生成渐变笔刷的控件。这是个根据用户选择生成渐笔刷的控件背景我当时在开发报告工具，使用这个工具用户可以从 SOL 或任何数据源制作报告。我需要在工具中提供给用户可以更改字段背景的工具。我找不到这样的控件，就决定自己做一个。该控件有几个控制。一个是颜色选择器。对于一个特定渐变停止点，用户可以更改颜色。颜色选择器有一个选择器控件，用户可以移动选择颜色。还有个用于渐变的控件。用于可以更改线性格笔刷起始点和结束点。对于径向笔刷，用户可以更改中心点、原点、半径 X 和半径 Y。用户可以删除渐变的停止点或添加停止点。用户可以从组合框中选择笔刷类型使用代码这是个用户控件，可以直接作为用户控件添加到窗口。
