+## Style a table row based on the row item
+
+<!-- UPDATE 10.0 API cross-link -->
+
+Apply a stylesheet class to a row of the grid based on the row item using the `RowClass` parameter.
+
+In the following example:
+
+* A row item is represented by the `Person` [record](/dotnet/csharp/language-reference/builtin-types/record). The `Person` record includes a `FirstName` property.
+* The `HighlightJulie` method applies the `highlight` class styles to any row where the person's first name is "`Julie`."
+
+```razor
+<QuickGrid ... RowClass="HighlightJulie">
+    ...
+</QuickGrid>
+
+@code {
+    private record Person(int PersonId, string FirstName, string LastName);
+
+    private string HighlightJulie(Person person) =>
+        person.FirstName == "Julie" ? "highlight" : null;
+}
+```

 ## Entity Framework Core (EF Core) data source
 
 Use the factory pattern to resolve an EF Core database context that provides data to a `QuickGrid` component. For more information on why the factory pattern is recommended, see <xref:blazor/blazor-ef-core>.
