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.v18.2.dll

Declaration

public event EventHandler ValueChanged
Public Event ValueChanged As EventHandler

The event handler EventHandler receives an argument of the EventArgs type.

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.

Note

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.
