    int rowHandle


Name Type Description
rowHandle Int32

An integer value identifying the master row being tested by its handle.


Type Description

true if the specified master row can be expanded; otherwise, false.


The CanExpandMasterRow function indicates whether the master row’s detail clone corresponding to the default master-detail relationship can be opened.
The default relationship is identified by the GridView.DefaultRelationIndex property.

See the GridOptionsDetail.AllowExpandEmptyDetails option to control whether empty details can be opened in the GridControl.


Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CanExpandMasterRow member must not be invoked for these Views. The CanExpandMasterRow member can only be used with real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
