This example shows how to change viewer options from the controller.

First, you need to add the StiMvcViewer component to the view page:

@using Stimulsoft.Report.Mvc;

...

@Html.Stimulsoft().StiMvcViewer(@ViewBag.ViewerOptions)

In the options above we define several actions, and we need to add it in the controller.

The GetReport() action loads the report template and returns answer to the client part of the viewer using the GetReportResult() static method. In the parameters of this method, the report object should be passed:

public ActionResult GetReport()
{
	// Create the report object
	var report = new StiReport();

	// Load report template
	report.Load(Server.MapPath("~/Content/Reports/SimpleList.mrt"));

	return StiMvcViewer.GetReportResult(report);
}

...

To return result, use ViewerEventResult() method:

...

public ActionResult ViewerEvent()
{
	return StiMvcViewer.ViewerEventResult();
}

...

Finally, use StiMvcViewerOptions() method to change viewer options:

...

public ActionResult Index()
{
	var viewerOptions = new StiMvcViewerOptions();
	viewerOptions.Actions.GetReport = "GetReport";
	viewerOptions.Actions.ViewerEvent = "ViewerEvent";
	viewerOptions.Appearance.FullScreenMode = true;
	viewerOptions.Toolbar.Zoom = 75;
	viewerOptions.Toolbar.ViewMode = Stimulsoft.Report.Web.StiWebViewMode.MultiplePages;
	viewerOptions.Theme = Stimulsoft.Report.Web.StiViewerTheme.Office2013WhiteViolet;

	// Passing options via ViewBag
	ViewBag.ViewerOptions = viewerOptions;

	return View();
}
