Telerik MVC 扩展：网格：在 Ajax 绑定调用期间，为什么查询字符串中回发这么多数据？

我使用 Ajax 与网格绑定，并遇到了一个问题：当我尝试在网格上执行调用 Ajax 调用的操作（如排序）时，ASP.NET MVC 抛出 HttpRequestValidationException。

使用 Fiddler，我能够确定我的浏览器正在尝试在查询字符串中回发我的整个模型，并且有一些字符会触发 ASP.NET 的请求验证。

我可以通过简单地添加

[ValidateInput(false)]

到我的控制器操作来解决这个问题。

我想知道为什么网格会发回如此多的数据？并且这是我的代码或 Telerik 的错误的症状吗？

这是我在 Fiddler 中看到的内容（请注意极长的查询字符串，即使 HTTP 动词是“POST”）。

原文

I am using Ajax binding with the Grid and ran into a problem where ASP.NET MVC was throwing a HttpRequestValidationException when I attempted an operation on the grid that invoked the Ajax call (like sorting).

Using Fiddler I was able to determine my browser was attempting to post back my entire model in the query string and there were some characters that would have triggered ASP.NET's request validation.

I was able to work around this by simply adding

[ValidateInput(false)]

to my controller action.

I'm wondering why was the grid sending back so much data? And is this a symptom of a bug in my code or Telerik's?

Here is what I saw in Fiddler (note the extremely long query string, even though the HTTP verb is "POST").
