Telerik的ASP.NET AJAX radgrid控件的MVC和ViewState的？ [英] Telerik ASP.NET Ajax RadGrid in MVC and ViewState?

问题描述

这是正确的，在MVC的ASP.NET AJAX控件。我知道，我知道，有Telerik的MVC控制，但Telerik的MVC电网没有我需要的一切，所以我使用ASP.NET AJAX控件死心塌地。

That's right, an ASP.NET Ajax control in MVC. I know I know, there are Telerik MVC controls but the Telerik MVC grid doesn't have everything I need so I'm dead set on using the ASP.NET Ajax control.

不管怎么说，我有radgrid控件和运行伟大。当我使所有的花里胡哨，如分页，排序，过滤等。它看起来像它在eventargument变量后放GROUP BY /过滤/排序数据将出现问题：

Anyways, I have the RadGrid up and running great. The problem occurs when I enable all the bells and whistles such as paging, sorting, filtering etc. It looks like it puts the group by/filter/sort data in an eventargument post variable:

__EVENTARGUMENT  FireCommand:2$RadGrid1$ctl00;GroupByColumn;Dialog

在我的情况下，当页面重新加载，没有什么变化。有什么我应该使这个在MVC工作？我按照指示在 http://www.telerik.com /help/aspnet-ajax/mvc-getting-started.html 但这不上来。在previous URL中的例子并不拥有所有花俏，所以我假设有我需要得到这个工作的额外步骤。

In my case, when the page reloads, nothing changes. Is there something I should enable for this to work in MVC? I have followed the instructions at http://www.telerik.com/help/aspnet-ajax/mvc-getting-started.html but this doesn't come up. The example in the previous url doesn't have all the bells and whistles, so I'm assuming there are additional steps I need to take to get this to work.

谢谢！

推荐答案

我是能够找到解决这一点，虽然这不是很pretty。它使用一个小的反射和硬codeD转换成对象的树。希望这将是任何人都需要的ViewState在MVC一个很好的起点。

I was able to find a solution to this, though it's not very pretty. It uses a little reflection and hard coded mapping to tree of objects. Hopefully this will be a good starting point for anyone needing ViewState in MVC.

基本上，它涉及到反序列化的ViewState成一个对象，然后使用反射，调用控件的LoadViewState与对象的树分支，在右侧。

Basically it involves deserializing the ViewState into an object then using reflection, call the Control's LoadViewState with the right branch in the object's tree.

    string viewState = Request.Form["__VIEWSTATE"];

    if (!string.IsNullOrEmpty(viewState))
    {
        LosFormatter formatter = new LosFormatter();

        object savedStateObject = formatter.Deserialize(viewState);

        MethodInfo method = grid.GetType().GetMethod("LoadViewState", BindingFlags.NonPublic | BindingFlags.Instance);

        // TODO: Find a less brittle/more elegant way to isolate the appropiate viewstate object for this control
        // In the case of Telerik's RadGrid, the key wasy find the tree that had an array of 13 objects
        method.Invoke(grid, new object[] { (((((((((savedStateObject as Pair).First as Pair).Second as Pair).Second as System.Collections.ArrayList)[1] as Pair).Second as System.Collections.ArrayList)[1] as Pair).Second as System.Collections.ArrayList)[1] as Pair).First });
    }

    string eventArgument = Request.Form["__EVENTARGUMENT"];

    if (!string.IsNullOrEmpty(eventArgument))
    {
        grid.RaisePostBackEvent(eventArgument);
    }
