webgrid

问题 How can I programatically (in javascript) get the current page number, last sort column and sort direction of the ASP.NET MVC WebGrid?

问题 Is there a way to override default MVC3 WebGrid sorting behavior to call my controller (which will perform server side sorting and return the data) when sort is called?
