How to use LINQ to SQL data source to create a Master-Detail report

It's possible to use LINQ to SQL API to bind an XtraReport document to data.
To set up report controls' bindings at design time, use the BindingSource component, which DataSource property is set to the parent (Master) object.
The relation between objects will be recognized automatically.
Then, use a Detail Report Band to create a Master-Detail report layout (see How to: Create a Master-Detail Report using Detail Report Bands).
In the example, Order -> Order_Detail collections (Northwind database) are used.

In addition, you can filter query results using Linq to Sql syntax.
For instance, use the following code to display a report document, containing Northwind Orders data filtered by customers, whose CustomerID starts with letter "B".

[C#]
NwindDataContextdc=newNwindDataContext();var_data=from_ordersindc.Orderswhere_orders.CustomerID.StartsWith("B")select_orders;XtraReport1report=newXtraReport1();BindingSourcebs=(BindingSource)report.DataSource;bs.DataSource=_data;
