Remarks
Views can have multiple detail views. The DefaultRelationIndex property specifies the index of a detail view (detail tab) to open when a user expands a master row.
/* The advBandedGridView1 view has two detail views: gridView1, cardView1.
* The following code makes the cardView1 the default detail view.
* The grid displays the corresponding detail tab when a user expands a master row.
*/
advBandedGridView1.DefaultRelationIndex = 1;
The DefaultRelationIndex property specifies a detail view processed by the IsMasterRowEmpty(Int32), SetMasterRowExpanded, and CanExpandMasterRow(Int32) methods.
Use the following methods to expand/collapse or get the information about the specified detail view:
- SetMasterRowExpandedEx(Int32, Int32, Boolean)
- GetMasterRowExpandedEx(Int32, Int32)
- CanExpandMasterRowEx(Int32, Int32)
- IsMasterRowEmptyEx(Int32, Int32)
