+## Collection columns
+
+When there are tables with one-to-many relationship, each table can reference the other one on the model definition. In this case you can define a grid column that shows the count of the referenced collection. You should use the contructor of the **Add** method to create the column including the collection expression as parameter, as a normal column definition:
+
+```c#
+    Columns.Add(o => o.OrderDatails);
+```
+
+This column can be filtered, sorted and searched as any other one.

 ## Component columns
 
 Sometimes you need to add a column that renders a component. In this case you must use an empty contructor of the **Add** method to create a column and its **RenderComponentAs** method to define the content that will be rendered in it:
