ASP.NET Core TreeView Remote Data Binding

The Telerik UI for ASP.NET Core TreeView supports remote data binding and you can display remote-storage data in the component.

To implement the remote data-binding feature, you need to specify a remote endpoint or web service returning data in a JSON or JSONP format, and utilize the Telerik UI for ASP.NET MVC DataSource as a mediator between the TreeView and the underlying data.

To make the connection to the remote endpoint and process the data properly, the data source requires information about the web service URL.

Usually, the remote binding is a preferable approach for TreeView data binding. You can configure it easily by adding the DataSource component in the helper definition. By default, the TreeView sends to the remote endpoint the id of the expanded node as a query string parameter. This way, you can filter the data collection in the Action method based on the received id parameter and return the appropriate child nodes to the DataSource of the component.

This example demonstrates how to bind the TreeView to remote data by using Html or TagHelpers.

This TreeView example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for ASP.NET Core or ThemeBuilder.
