GridView.ExpandGroupRow(Int32) Method

Expands the specified group row.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v24.2.dll

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

#Declaration

public void ExpandGroupRow(
    int rowHandle
)

#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.

#Remarks

The ExpandGroupRow method raises the GridView.GroupRowExpanding event. This event allows you to prevent the group row from being expanded. If a row has been expanded the GridView.GroupRowExpanded event is raised.

To expand group rows recursively use one of the other overloads of this method.

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 ExpandGroupRow member must not be invoked for these Views. The ExpandGroupRow 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.

#Example

The following example expands the focused group row.

if (gridView1.IsGroupRow(gridView1.FocusedRowHandle))
    gridView1.ExpandGroupRow(gridView1.FocusedRowHandle);
