Description

The Telerik UI for ASP.NET Core Grid component delivers the hierarchy feature, which enables you to display the table data in a hierarchical-like fashion visualizing, in this way, the relations between parent and child records.

To implement hierarchy in the Data Grid:

Set the ClientDetailTemplateId which specifies the id of the script element containing the client-side detail template of the ASP.NET Core Data Grid.
Define the script tag content that will be shown when the user expands the rows of the Data Grid.

For more information about the hierarchy feature, refer to the official Telerik UI for ASP.NET Core Data Grid product documentation on the available hierarchy implementations.

This Grid 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.
