#Remarks
The ParametrizedAction
class inherits the basic functionality of Actions from the ActionBase class.
Use Parametrized Actions to execute custom code when a user enters a value into an Action’s editor.
To access the input value, use the ParametrizedAction.Value property. The value is of the string type by default.
To specify another type for input values (integer or DateTime
), use the ParametrizedAction.ValueType property. For each type, XAF displays an appropriate control.
Note
For some value types, an Action Container cannot create an appropriate control. In this case, you have to implement a special Action Container.
Handle the ParametrizedAction.Execute event to execute custom code when a user enters a value into an Action’s editor. Use the handler’s ParametrizedActionExecuteEventArgs.ParameterCurrentValue parameter to access the input value.

Note
Code
Set the IModelActionWeb.IsPostBackRequired property to true to send a postback when a user executes an Action in an ASP.NET Web Forms application. For example, for Actions that download files or change the application’s language.
