ParametrizedAction.ValueChanged Event

Occurs after an end-user has typed and submitted a parameter in the Action’s editor, and after the ParametrizedAction.Value property has been changed in code.

Namespace: DevExpress.ExpressApp.Actions

Assembly: DevExpress.ExpressApp.v22.2.dll

NuGet Package: DevExpress.ExpressApp


public event EventHandler ValueChanged

Event Data

The ValueChanged event's data class is EventArgs.


Handle this event to execute custom code in response to a change in the current Parametrized Action’s ParametrizedAction.Value property. If you need to respond to the Action’s execution, handle the ParametrizedAction.Execute event, which is raised after the ValueChanged event.


An end-user can submit the typed parameter by pressing ENTER (in WinForms applications) or the button that accompanies the editor. So, do not use this event if you want to execute your code immediately after a value is selected in the editor. In this case, access the editor as described in the How to: Customize Action Controls topic.

The following code snippet (auto-collected from DevExpress Examples) contains a reference to the ValueChanged event.
