I've tried to get this working using this aspnetmvc-ajax sample code from telerik found here.
I'm using jquery ajax restful api for the remote data endpoint and I am returning the response in the exact format as shown in the above example but it doesn't work.
After the grid loads, an "undefined" is displayed as the first row in the grid despite the data from the ajax data call returning the data in the exact same format as shown in the above example.
I also added the code for the sample into my project and I tried a local data source in order to rule out jquery ajax as remote api being the problem with the same response data format as the sample code to see if the server side group paging is anyway dependent on the datasource.type being aspnetmvc. In this case I also get the same error as seen in my jquery ajax grid with remote group paging.
Has anyone been able to get group paging for a grid using a custom function for the transport read (jquery ajax) configuration?
Can anyone confirm whether it should work for this use case? And does anyone have an example?
Thanks in advance and appreciate your help.
