Group Rows 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.
