Property Value

Type	Description
GridColumnReadOnlyCollection	A GridColumnReadOnlyCollection object representing a read-only collection of columns involved in grouping.

Remarks

When grouping data by values of a column, the column is automatically added to the GroupedColumns collection. When canceling grouping by this column’s values, the column is removed from the collection. The column’s position within the collection matches the column’s GridColumn.GroupIndex property value.

To access all columns within a view, use the ColumnView.Columns property.

Note

The GroupedColumns collection contains only the first group column for merged group columns.
