Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v24.2.Core.dll

VB.NET

Public Event FocusedRowHandleChanged As FocusedRowHandleChangedEventHandler

Event Data

The FocusedRowHandleChanged event's data class is FocusedRowHandleChangedEventArgs. 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. Inherited from RoutedEventArgs.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
RowData	Returns the information about a new focused row.
Source

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. Inherited from RoutedEventArgs.
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. Inherited from RoutedEventArgs.

Remarks

The DataControlBase.CurrentItemChanged event is raised after the focused row’s underlying data object has been changed (e.g. row focus moves to another data row). However, when sorting or grouping, data rows are reordered, their handles are changed but the data object corresponding to the focused row is not changed. The DataControlBase.CurrentItemChanged event is not raised.

You can handle the DataViewBase.FocusedRowHandleChanging event to prevent users from focusing specific rows.
