I am trying to set up paging in my grid so that when a user navigates to a page only the data for that specific page is retrieved from the database and pushed down to the client.  Here is some sample code to give you an idea.

[GridAction]
public ActionResult GetGridData()
{
    var list = new List<UserViewModel>();
 
    for (int i = 0; i < 100; i++)
    {
        list.Add(new UserViewModel { Id = i});
    }
 
    var pagingList = list.Skip(20).Take(5).ToList();
 
    return View(new GridModel { Data = pagingList, Total = list.Count});
}

The JSON sent down to the client is this...

{"data":[{"Id":24},{"Id":23},{"Id":22},{"Id":21},{"Id":20}],"total":5}

So obviously the correct JSON is getting serialized but for some reason the Total value is not getting serialized as it was set.

I have attached a solution demonstrating the issue.  There should be more than 1 page.

Hello Oliwa,

In order to instruct the grid to on perform all paging/sorting etc. operation on the data that has been set custom binding should be used. Otherwise the grid will attempt to page the data that is set inside Data property.
