public event CellValueChangedEventHandler CellValueChanged

VB.NET

Public Event CellValueChanged As CellValueChangedEventHandler

Event Data

The CellValueChanged event's data class is CellValueChangedEventArgs. 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.
IsReset	Gets whether the cell’s property value is reset when a user clicks the Reset context menu’s item. In this case, the PropertyDescriptor.ResetValue(Object) is called.
NewValue	Gets the new value that is assigned to the cell.
OldValue	Gets the cell’s previous value that is replaced with the new value.
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.
Row	Gets the row whose value is changed.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

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

A grid raises the CellValueChanged event after a cell’s value has been changed. The CellValueChanged event doesn’t fire when a cell’s value is changed using the methods provided by a data source.
