The ASPxGridView supports data grouping against one or more columns.
Grouping is allowed if the following properties are set to true:
- SettingsBehavior.AllowGroup
- SettingsBehavior.AllowSort
End-users can group data by dragging column headers to the Group Panel.
This panel's visibility is controlled by the Settings.ShowGroupPanel option.
Use the GroupCount property to lookup the number of columns used to group data.
These columns can be obtained using the GetGroupedColumns() method.
