Description

The Telerik for ASP.NET Core TreeList component supports a comprehensive set of events which enable you to provide a fluent experience and smooth interaction with the component. All events are handled in the Console Log when you interact with the component.

This demo shows how to handle the Edit event, which is fired when the user creates or edits a row, the Save event, which is fired when a row is saved, the Remove event, which is fired when a row is removed, the DataBound event, which is fired when the component is bound to data from data source, and the DataBinding event, which is fired before the component is bound to data from the data source.

You can also use the ASP.NET Core TreeList events in both the TagHelper and HtmlHelper mode of the component depending on your preferences or background.

Additional Apps

This TreeList 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.
