Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v24.2.dll

Declaration

C#

public void SetMasterRowExpanded(
    int rowHandle,
    string relationName,
    bool expand
)

VB.NET

Public Sub SetMasterRowExpanded(
    rowHandle As Integer,
    relationName As String,
    expand As Boolean
)

Parameters

Name	Type	Description
rowHandle	Int32	An integer value identifying the master row by its handle.
relationName	String	A string representing the required relationship’s name.
expand	Boolean	true to open the specified detail; false to hide it.

Remarks

This overload opens or hides a specific detail View which is identified by the name of the relationship it displays. To open or hide a detail View by its index amongst the other details, the GridView.SetMasterRowExpandedEx method can be used. The SetMasterRowExpanded and GridView.SetMasterRowExpandedEx methods are equivalent and differ only in the second parameter which identifies the required detail View. See the GridView.SetMasterRowExpandedEx topic for more information.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the SetMasterRowExpanded member must not be invoked for these Views. The SetMasterRowExpanded 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.
