GridView.IsMasterRowEmpty(Int32) Method

Indicates whether a particular master row’s default detail View is empty.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v23.2.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation

Declaration

C#

public bool IsMasterRowEmpty(
    int rowHandle
)

VB.NET

Public Function IsMasterRowEmpty(
    rowHandle As Integer
) As Boolean

Parameters

Name	Type	Description
rowHandle	Int32	An integer value specifying the tested master row by its handle.

Returns

Type	Description
Boolean	true if the master row’s default detail View is empty; otherwise, false.

Remarks

This method determines whether the detail clone identified by the GridView.DefaultRelationIndex property value has data. It uses the GridView.IsMasterRowEmptyEx method internally. Please refer to the latter method’s description for details.

Note

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

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.
