Description

The ForeignKey column functionality of the Telerik UI for ASP.NET MVC Grid component is primarily used for matching the value of a bound property to a desired text field from a collection that is external for the Data Grid. The ForeignKey column approach follows the convention of the SQL ForeignKey functionality that is used for linking two tables based on a foreign key.

This demo shows how to implement a foreign key column which fetches its values from a DataSource in the ASP.NET MVC Data Grid which hosts the Telerik UI for ASP.NET MVC DropDownList component as an editor for modifying the data.

For more information about the ForeignKey column capabilities, refer to the official Telerik UI for ASP.NET MVC Data Grid product documentation on the available column settings.
