Scenario: You are working with a dataset containing customer orders and order details in a hierarchical structure. How would you use DataRelations to retrieve order details for a specific customer's orders?
- Set the Nested property to true
- Set the RelationName property to "OrderDetails"
- Use the GetChildRows method
- Use the GetParentRow method
To retrieve order details for a specific customer's orders using DataRelations, you would use the GetChildRows method to obtain the child rows related to the customer's orders. This method allows accessing the related child rows based on the specified parent row. The GetParentRow method is used to retrieve the parent row from a child row. Setting the Nested property to true enables navigating through hierarchical data. Setting the RelationName property to "OrderDetails" specifies the relation to use for retrieving order details. This approach leverages the hierarchical structure defined by DataRelations to efficiently access related data.
