I have been working on some admin screens for an internal application and we recently purchased the Telerik Dev Tools library for use on the site. The first scenario I tackled was displaying a list of the application’s active users.
The Kendo UI Grid supports both client side rendering and server side rendering.
Client-side rendering uses HTML/JS to setup the grid and then makes a remote call to load data into the Grid.
Server-side rendering a developer uses C# to setup the grid and populate its contents from a property on the Model.
At first, due to my natural preference for C# vs. JavaScript, I tried using the server-side rendering. The grid rendered with the data in it but sorting, filtering, and grouping did not work.
Next, I tried client-side rendering. I found this wonderful article describing how to setup your controller endpoints to take in the correct parameters that the Kendo UI Grid sends but I still had the same problem. Sort wouldn’t work. However, this time, I had a pretty good idea why.
Based on the fore-mentioned article, I setup my controller endpoint with skip, take, page, pageSize, sort, and filter parameters.
I defined SortDescription class:
Then I defined the FilterContainer and FilterDescription classes:
So far so good? Or so I thought…
I launch my site (in the Azure simulator of course 
) and turn on the web console within FireFox so I can monitor the activity. I see the call come across from the Kendo UI JavaScript.
The Query String of the request looks like this:
All the usual suspects are there.
I even used a URL decoder ring to make it a bit more readable just to be sure I knew what I was looking at.
The URL looks okay but when my controller picks it up I have an array of SortDescription objects with one item in item. As expected. However, the Dir and Field properties are null. Based on the query string I am expecting Dir=”asc” and Field=”LastName”.
I thought the likely problem would be some serialization failure. So I tried modifying my SortDescription class to make directly to the case sensitive names.
But it makes no difference.

I am having the exact same problem with this UI. I’m trying to do my sorting and paging on the serverside, but the same issue arrises. I get an array of objects for my sort parameter with one item, and it has nulls for both the Dir and Field.

Hi!
try to put this in your datasource:
dataSource: {
transport: {
read: {
type: ‘POST’,
url: ‘yyxxzz’,
dataType: ‘json’,
// 1
contentType: ‘application/json; charset=utf-8’
},
// 2
parameterMap: function (options) {
return JSON.stringify(options);
}
},
}
