DataControlBase.AutoGeneratedColumns Event

Occurs after the columns have been automatically generated.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v21.1.Core.dll

Declaration

public event RoutedEventHandler AutoGeneratedColumns

Event Data

The AutoGeneratedColumns event's data class is RoutedEventArgs. The following properties provide information specific to this event:

Property Description
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.

The event data class exposes the following methods:

Method Description
InvokeEventHandler(Delegate, Object) When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation.
OnSetSource(Object) When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.

Remarks

If the grid’s DataControlBase.AutoGenerateColumns option is enabled, binding the grid to a data source automatically generates columns for all data source properties. After all columns have been created and added to the GridControl.Columns collection, the grid fires the AutoGeneratedColumns event. Handle this event to specify column settings (e.g., assign column editors, hide individual columns, and so on).

The AutoGeneratedColumns event is not raised if the grid columns are explicitly specified (for instance, in the XAML file) and the DataControlBase.AutoGenerateColumns property is set to AutoGenerateColumnsMode.KeepOld, or if the DataControlBase.AutoGenerateColumns property is set to AutoGenerateColumnsMode.None.
