GroupsCollection Class

Returns the collection of Group objects. This property is read-only at run-time.
Syntax
'Declaration
 
Public Class GroupsCollection 
   Inherits Infragistics.Shared.KeyedSubObjectsCollectionBase
public class GroupsCollection : Infragistics.Shared.KeyedSubObjectsCollectionBase
Remarks

The Groups property is used to access the collection of Group objects associated with an Band object. An Group is a group of columns that appear together in the grid, and can be resized, moved or swapped together as a unit.

Each Group object in the collection can be accessed by using its Key value. Group objects in this collection do not support an Index value as the position of the object within the collection is not significant.

Example
Following code shows how to create groups in the UltraGrid. It creates two groups in the first band.
