public event TreeListCellValueChangedEventHandler CellValueChanged

Event Data

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

Property Description
Cell Gets or sets the CellValue object consisting of information about the cell being processed. Inherited from TreeListCellValueEventArgs.
Column Gets a column that contains the edited cell. Inherited from TreeListCellValueEventArgs.
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.
Node Gets the processed node. Inherited from TreeListNodeEventArgs.
OldValue Gets the cell’s previous 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 processed row. Inherited from TreeListNodeEventArgs.
Source Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.
Value Gets or sets the processed cell’s value. Inherited from TreeListCellValueEventArgs.

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 TreeListView raises the CellValueChanged event after a cell’s value has been changed. This occurs in the cases listed below:

  • An end-user has changed a cell’s value and closed the cell’s inplace editor.
  • A cell’s value has been changed in code using the GridControl.SetCellValue method.

The CellValueChanged event does not fire when a cell’s value is changed using the methods provided by a data source.

The event parameter’s TreeListEditorEventArgs.Node and TreeListCellValueEventArgs.Column properties identify the cell whose value has been changed. The cell’s new value is returned by the TreeListCellValueEventArgs.Value property.
