Grouping in Code

• May 22, 2020

Grouping

To group data by the values of a 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 or not, 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.
