This example shows how to register data in the dashboard from code.

For example, we will load and register a JSON data file. To display a ready-made dashboard, we need a viewer. Add the StiMvcViewer component to the view and set the necessary options:

@using Stimulsoft.Report.Mvc;

...

@Html.Stimulsoft().StiMvcViewer(new StiMvcViewerOptions()
{
	Actions =
	{
		GetReport = "GetReport",
		ViewerEvent = "ViewerEvent"
	}
})

To register data in the dashboard, it is enough to call the special RegData() method, and specify the name of the data source, its alias, and pass the prepared DataSet object as parameters. To load a JSON file into a DataSet object, you can use a special StiJsonConnector class, which contains the necessary set of methods for conversion. All of these steps can be done in the GetReport action, which should return the dashboard object to the viewer:

public ActionResult GetReport()
{
	// Create new dashboard
	var report = StiReport.CreateNewDashboard();

	// Load dashboard template
	report.Load(Server.MapPath("~/Dashboards/Dashboard.mrt"));

	// Load a JSON file
	var jsonBytes = System.IO.File.ReadAllBytes(Server.MapPath("~/Dashboards/Demo.json"));

	// Get DataSet from JSON file
	var json = StiJsonConnector.Get();
	var dataSet = json.GetDataSet(new StiJsonOptions(jsonBytes));

	// Remove all connections from the dashboard template
	report.Dictionary.Databases.Clear();

	// Register DataSet object
	report.RegData("Demo", "Demo", dataSet);

	// Return template to the Viewer
	return StiMvcViewer.GetReportResult(report);
}


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