Related API Members

MasterRowEmptyEventArgs is the data class for the following events:

• GridView.MasterRowEmpty

Remarks

The GridView.MasterRowEmpty event enables you to specify whether a particular master row’s detail contains data. Thus, the MasterRowEmptyEventArgs class provides the inherited CustomMasterRowEventArgs.RowHandle property identifying the currently processed master row. The detail whose empty state is to be specified can be identified using the CustomMasterRowEventArgs.RelationIndex property. Finally, the MasterRowEmptyEventArgs.IsEmpty property is used to specify whether the detail contains data.

MasterRowEmptyEventArgs objects are automatically created, initialized and passed to GridView.MasterRowEmpty event handlers.
