The following are the main members that you will need to work with when using a DataControlDetailDescriptor:

Member Description
DataControlDetailDescriptor.ItemsSourcePath Gets or sets the detail grid’s data binding by specifying the path relative to the master grid’s records.
DataControlDetailDescriptor.DataControl Gets or sets the GridControl that displays detail data.
DataViewBase.DetailHeaderContent Gets or sets the detail section’s header content.

If you are using the DataControlDetailDescriptor to display a Detail, the following integration features become available:

  • Detail synchronization

The following example shows how to create a new grid and set up Master-Detail data representation in code. When setting up a Master-Detail hierarchy, a detail grid and a custom detail section are placed within a tabbed container. So, the following Detail Descriptor types are used: DataControlDetailDescriptor, ContentDetailDescriptor, and TabViewDetailDescriptor.
