public event CellValueChangedEventHandler CellValueChanged
Public Event CellValueChanged As CellValueChangedEventHandler
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. |
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.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the CellValueChanged event.
