 The `SelectedItems` collection is compared against the Grid `Data` collection in order to determine which rows will be highlighted. The default behavior of the framework is to compare objects by their reference.
 
-When the `SelectedItems` are obtained from a different data source to the Grid (e.g., from a separate service method and not from the view-model), the references may not match and so there will be no highlighted items. In such cases, you have to [override the `Equals` method of the underlying model class]({%slug grid-state%}) so that it matches them, for example, by a unique identifier rather than by reference so that two objects can be equal regardless of their origin, but according to their contents. When you are overriding the `Equals` method, it is also recommended to override the [`GetHashCode`](https://docs.microsoft.com/en-us/dotnet/api/system.object.gethashcode) method as well.
