Description

This demo shows how the Telerik UI ListView for ASP.NET Core can be bound to a custom data source when none of the built-in data-binding types are suitable. To connect to the remote endpoint and process the data properly, the data source requires information about the web service URL(s), the request type, the response data type, and the structure (schema) of the response.

More about the Telerik UI ListView for ASP.NET Core

The service is available in this repository Kendo UI Demos Service
