Public Event StartGrouping As RoutedEventHandler
The StartGrouping event's data class is RoutedEventArgs. The following properties provide information specific to this event:
|Handled||Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.|
|Source||Gets or sets a reference to the object that raised the event.|
Each time the grid's data is grouped or ungrouped by a column, the grid does the following:
- Fires the GridControl.StartGrouping event.
- Performs data grouping.
- Fires the GridControl.EndGrouping event.
