GridView.CollapseGroupRow(Int32, Boolean) Method

Collapses the specified group row and optionally any child group rows at all nesting levels.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v20.2.dll

Declaration

public void CollapseGroupRow(
    int rowHandle,
    bool recursive
)
Public Sub CollapseGroupRow(
    rowHandle As Integer,
    recursive As Boolean
)

Parameters

Name Type Description
rowHandle Int32

An integer value identifying the group row by its handle. If the specified handle points to a data row this method does nothing.

recursive Boolean

true to collapse any child group rows at all nesting levels; false to preserve the expanded state of any child group rows.

Remarks

The CollapseGroupRow method raises the GridView.GroupRowCollapsing event. This event allows preventing the group row from being collapsed. If a row has been collapsed, the GridView.GroupRowCollapsed event is raised.

Please refer to the Working with Groups in Code topic for additional information.

NOTE

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