GridView.CollapseMasterRow(Int32, String) Method

Collapses a master row's detail View, identified by the name of the relationship associated with it.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v20.2.dll

Declaration

public void CollapseMasterRow(
    int rowHandle,
    string relationName
)
Public Sub CollapseMasterRow(
    rowHandle As Integer,
    relationName As String
)

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.

Remarks

The CollapseMasterRow method can be used as an alternative to the GridView.SetMasterRowExpanded method which requires an additional parameter that specifies how the row's expanded state should be changed.

Before a master row is collapsed the GridView.MasterRowCollapsing event is raised. If the event handler prohibits row from being collapsed the CollapseMasterRow method does nothing. If the row has been collapsed the GridView.MasterRowCollapsed event is raised.

Please refer to the Master-Detail Relationships topic for additional information.

NOTE

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