Declaration
Property Value
| Type | Default | Description |
|---|---|---|
| Boolean | **false** | true, to perform a postback when a user executes the Action; false, to perform a callback. |
Remarks
Set this property to true if you need to send a postback when a user executes an Action in an ASP.NET application. For example, the built-in Export Action is executed on postback, because a postback is required to transmit a file to the client.
To specify this property, open the Model Editor for the ASP.NET module project (MySolution.Module.Web) and navigate to the ActionDesign | Actions | <Action> node.
