一般局部视图：如何设置一个泛型类的模式？ [英] Generic partial view: how to set a generic class as model?

问题描述

我想建立一个ASP.NET MVC应用程序的通用网格视图。

I'm trying to build a generic grid view in an ASP.NET MVC application.

让我做一些code解释：

Let me explain with some code:

public interface ITrustGrid<T>
{
    IPagedList<T> Elements { get; set; }
    IList<IColumn<T>> Columns { get; set; }
    IList<string> Headers { get; }
}

这是一类，让我一组列和前pressions在我的控制器的接口。

This is an interface of a class that allows me to set columns and expressions in my controller.

我通过实现，以这样的局部视图：

I pass implementations to a partial view like this:

<% Html.RenderPartial("SimpleTrustGridViewer", ViewData["employeeGrid"] as TrustGrid<EmployeeInfoDTO>); %>

问题是，我无法弄清楚如何使呈现电网通用的局部视图。

The problem is that I can't figure out how to make the partial view that renders the grid generic.

在换句话说，我希望把这个：

In other words, I want to turn this:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ITrustGrid<EmployeeInfoDTO>>" %>

弄成这个样子：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ITrustGrid<T>>" %>

=>我怎样才能让我的部分观点以最简单的方式通用的？

=> How can I make my partial view generic in the most simple way?

编辑：

我通过使用具有它返回一个非通用TrustGrid公共TrustGrid G​​etTrustGrid（）方法TrustGridBuilder解决了这个。该TrustGrid包含字符串而非LINQ的东西。所以，我执行了GetTrustGrid（）方法中的LINQ，并把串在TrustGrid对象。

I solved this by using a TrustGridBuilder that has a public TrustGrid GetTrustGrid() method which returns a non-generic TrustGrid. The TrustGrid contains strings instead of linq stuff. So I execute the linq in the GetTrustGrid() method and put the strings in a TrustGrid object.

感谢大家帮助我在正确的轨道上。

Thanks for everybody to help me on the right track.

推荐答案

这是不可能做到这一点这样的。原因是的.aspx 将生成你没有上太多的控制的一类，你不能一个泛型参数添加到它。我想最简单的方法就是把它作为对象。

It's not possible to do it like that. The reason is the .aspx will generate a class that you don't have much control on it and you can't add a generic parameter to it. I guess the most straightforward way is to pass it as object.
