Namespace: DevExpress.XtraGrid.Views.Grid
Assembly: DevExpress.XtraGrid.v24.2.dll
NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation
#Declaration
#Parameters
Name | Type | Description |
---|---|---|
row |
Int32 | An integer value identifying the master row by its handle. |
#Remarks
The ExpandMasterRow method can be used as an alternative to the GridView.SetMasterRowExpanded method, which requires an additional parameter specifying how the row’s expanded state should be changed.
The GridOptionsDetail.AllowExpandEmptyDetails option controls whether empty details can be expanded. If this option is set to false and the default detail is empty, the ExpandMasterRow method will not expand this detail. Instead, the first non-empty detail will be expanded.
Before a master row is expanded, the GridView.MasterRowExpanding event is raised. If the event handler prohibits expanding the row, the ExpandMasterRow method does nothing. If the row is successfully expanded, the GridView.MasterRowExpanded event is raised.
Please refer to the Master-Detail Relationships topic, for additional information.
