Description

The Telerik ListView UI component for ASP.NET Core comes with functionality for editing its records.

To implement the functionality, you must:

Define the model and item template
Add buttons for the create, update, and destroy operations
Define the editor template in a file that uses the name of the edited model and place it in the ~Views\Shared\EditorTemplates directory of your project
Enable the editing functionality using .Editable()
Specify and implement the action methods and the model id of the data source

This ListView 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.
