提问by Fanda
How can/should I create some "custom control" in ASP.NET MVC 3? I have red about partial views, ViewUsersControl, Html.RenderAction, but I still don't know, which way is the proper MVC way for razor views.
我可以/应该如何在 ASP.NET MVC 3 中创建一些“自定义控件”？我有关于部分视图的红色，ViewUsersControl, Html.RenderAction，但我仍然不知道，哪种方式是剃刀视图的正确 MVC 方式。
If I need to render some ajax component to view, I can imagine to do it by partial view, but what if I want to render section with custom logic?
如果我需要渲染一些ajax组件来查看，我可以想象通过部分视图来完成，但是如果我想用自定义逻辑渲染部分怎么办？

3) Child Actions
3) 子动作

You may use
您可以使用
@{Html.RenderPartial("YourCustomView",YourModel);}
For instance, In your Sharedfolder create a new Viewand name it "_MyCustomControl"
例如，在您的Shared文件夹中创建一个新的View并将其命名"_MyCustomControl"
Then in the code write :
然后在代码中写：
@model YourNameSpace.Models.YourModel
@{
Layout = null;
}
@*Here write your control's markup*@
Then in your Views where you want to use this "control"you add:
然后在您要使用它的视图中"control"添加：
@{Html.RenderPartial("_MyCustomControl",new YourModel { args });}
If you get into trouble with RenderPartialcheck this out
如果你在检查这个时遇到麻烦RenderPartial

As you have mentioned that you can use Partial Views. Yes you can use Partial Views, which is the most effective and efficient way.
正如您所提到的，您可以使用局部视图。是的，您可以使用局部视图，这是最有效和最高效的方法。
For Ajax rendering you can always use
对于 Ajax 渲染，您始终可以使用
@using (Ajax.BeginForm("Details", new { id = Model.Post.PostId }, new AjaxOptions
{

In addition to all the other answers for this post, I can offer you the use of EditorFor and DisplayFor templates. These are useful when you want to easily render or edit a custom type. It'll handle validation nicely (which can get weird when using partials) and you can nest them recursively (again another feature that isn't obviously handy until you need it).
除了这篇文章的所有其他答案之外，我还可以为您提供 EditorFor 和 DisplayFor 模板的使用。当您想要轻松渲染或编辑自定义类型时，这些非常有用。它将很好地处理验证（使用部分时可能会变得奇怪）并且您可以递归地嵌套它们（这又是另一个在您需要之前显然不方便的功能）。
You can also use Html.RenderAction()or Html.Action()to call another controller action within a view and display the results in-line in the page. This is probably the closest to what you need as it allows you to render a partial, include code in the controller and it also allows for the passing of parameters.
您还可以使用Html.RenderAction()或Html.Action()在视图中调用另一个控制器操作并在页面中内嵌显示结果。这可能是最接近您需要的，因为它允许您渲染部分，在控制器中包含代码，并且还允许传递参数。
