使用.NET集合编辑器而不使用属性网格控件

我的表单上有一个PropertyGrid.我的老板认为这很难看.粗野.性格单纯.

他想要一个漂亮,整洁,干净的形式.这是一个问题:其中一个属性是我们自己种植的物品的集合.他喜欢这个系列的收藏编辑器.

我知道我可以建立自己的收藏编辑器.但有没有一个干净,简单的解决方案来节省我几个小时的编码,这样我可以直接创建和使用Collection编辑器而无需使用属性网格？

你可以从UITypeEditor(via TypeDescriptor)获得这个功能,但这不是一件容易的事 - 你需要设置一个IServiceProvider,一个IWindowsFormsEditorService,理想的是ITypeDescriptorContext- 相当一点.如果您不熟悉这些工具,手动操作可能会更简单.

或者 - 看看SmartPropertyGrid.NET,替代PropertyGrid.

更新:这是一个工作示例......绝对不是一件容易的事,但随意窃取代码.它仅适用于模态编辑器,而不适用于下拉列表.它也不是"关注点分离"的一个很好的例子.这MyHelper堂课很有意思.
