Grouping in Code
Grouping
To group data by the values of the specified column at runtime, do one of the following:
Specify the column’s GridColumn.GroupIndex property. This property specifies whether the column takes part in grouping, and at which level.
grid.Columns["UnitPrice"].GroupIndex = 0;
Use the GridControl.GroupBy method.
grid.GroupBy("UnitPrice");
Ungrouping
To ungroup data by the values of a single column, do one of the following:
- Set the column’s GridColumn.GroupIndex property to -1.
- Call the GridControl.UngroupBy method.
To ungroup the grid, use the GridControl.ClearGrouping method.
Note
The GridViewBase.AllowGrouping property specifies whether an end-user can group data. Setting this property to false does not ungroup data.
