Group Rows in Code

• Apr 07, 2022

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.

  C#

  grid.Columns["UnitPrice"].GroupIndex = 0;
  

• Use the GridControl.GroupBy method.

  C#

  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.
