AfterGroupPosChanged Event

Occurs after an UltraGridGroup object has been moved, sized, or swapped.
Syntax
'Declaration
 
Public Event AfterGroupPosChanged As AfterGroupPosChangedEventHandler
public event AfterGroupPosChangedEventHandler AfterGroupPosChanged
Event Data

The event handler receives an argument of type AfterGroupPosChangedEventArgs containing data related to this event. The following AfterGroupPosChangedEventArgs properties provide information specific to this event.

PropertyDescription
GroupHeaders groups (read-only)
GroupPosChangedType header position changed type (read-only)
Remarks

The action argument indicates which action occurred to the group or groups: moving, swapping, or sizing.

The groups argument returns a reference to a Groups collection that can be used to retrieve references to the UltraGridGroup object or objects that were moved, swapped, or sized. You can use this reference to access any of the returned collection's properties or methods, as well as the properties or methods of the objects within the collection.

This event is generated after one or more groups are moved, swapped, or sized, either programmatically, or by user interaction. A group can be sized programmatically by setting its Width property and can be moved programmatically by setting its header's VisiblePosition property.

The VisiblePosition property of a group's header can be used to determine the new position of a group that was moved or swapped.

To prevent the user from attempting to move or swap a group, set the AllowGroupMoving or AllowGroupSwapping properties, respectively.

The AfterColPosChanged event is generated after one or more columns are moved, swapped, or sized.

The BeforeGroupPosChanged event, which occurs before one or more groups are moved, swapped, or sized, is generated before this event.

Example
Following code shows some of the information available in AfterGroupPosChanged event.
