    Property Value

    A DataGridDetailDescriptionCollection that contains DataGridDetailDescription objects that provide information on the details that will be contained in the grid, including sorting, grouping, and child detail descriptions.
    Example
    All examples in this topic assume that the grid is bound to the Employees table of the Northwind database, unless stated otherwise
    The following example demonstrates how to explicitly define detail descriptions for the DataRelations found in the DataTable to which the grid is bound and how to calculate statistical functions for a detail description whose results will be displayed in the StatRows contained in the footer sections of the details to which the description's corresponding detail configuration will be applied.
