Kendo grid long query string issue

[MUDIAM]

Hi 

We are using a kendo grid with a WCF service to load data in the grid. The grid has sorting, filtering and paging, we are getting 404 error due to long query strings that add the filters for EF behind the scene. These query strings are unmanageable, can you please suggest a way to reduce it and make it work for all clients.

Hello Mudiam,

Thank you for the query string and details provided.

Actually, the Kendo UI Grid is working on the visualization of the provided data. 

I am not sure why all the escaping is needed. Is it convenient for you to provide a runnable, isolated, sample project? Examining this project will let us replicate the issue locally and further troubleshoot it.

Looking forward to hearing back from you.

Kind Regards,
Anton Mironov
