Example

The following code implements the controller action and returns the Report Designer model. For more information on Report Designer server-side configuration, refer to the following help topic: Report Designer Server-Side Configuration (ASP.NET MVC).

The GetModel method obtains a client-side model and sets the ASPxReportDesigner.AllowMDI property to false. The GetJsonModelScript method serializes the model to JSON. The model is subsequently sent to the client.

      var model = generator.GetModel(
              reportUrl,
              // A report that the Report Designer loads when the application starts.
