Public Class CellValueChangedEventArgs
    Inherits CellEventArgs

CellValueChangedEventArgs is the data class for the following events:

Remarks

The TreeList.CellValueChanged and TreeList.CellValueChanging events fire in response to cell value modifications. The CellValueChangedEventArgs class gives you information about the cell and its new value. It is derived from the CellEventArgs class to provide data about the cell via the inherited NodeEventArgs.Node and CellEventArgs.Column properties. The CellValueChangedEventArgs.Value property is introduced to provide access to the newly assigned cell value.

CellValueChangedEventArgs objects with proper settings are automatically created and transmitted to TreeList.CellValueChanged and TreeList.CellValueChanging event handlers.

The following code snippets (auto-collected from DevExpress Examples) contain references to the CellValueChangedEventArgs class.
