修改MVC3网格的排序头URL（@ grid.GetHtml）

Question

我有一些MVC3网格。

@grid.GetHtml(
        tableStyle: "grid",
        headerStyle: "CenteredHeader",
        alternatingRowStyle: "alt",
        columns: grid.Columns(

在该方法中，我通过一些通用 checkboxes过滤数据。

[IsAuthenticated]
[HttpPost]
public ActionResult Movies(int? id, FormCollection formCollection)
{

当我尝试对已过滤的数据进行排序时问题apearas。我的意思是列标题URL没有任何参数，我也不能使用[HttpPost]。

有任何线索，当我点击这些复选框时，如何访问所选复选框或修改列标题网址？

此链接包含MVC3 Grid的列标题网址。

http://localhost:16349/MyWebsite/Movies/807?sort=TechnologyName&sortdir=DESC

谢谢！

P.S。代码
