This example is outdated, you can check out the many other new examples in this category. This example shows how to load a dashboard from the server-side. First of all, load scripts:

<script src="/scripts/stimulsoft.reports.js" type="text/javascript"></script>
<script src="/Scripts/stimulsoft.dashboards.js" type="text/javascript"></script>
<script src="/scripts/stimulsoft.viewer.js" type="text/javascript"></script>

Next, create GetDashboard file:

public partial class GetReport : System.Web.UI.Page
{
	protected void Page_Load(object sender, EventArgs e)
	{
		// Get the dashboard ID
		var dashboardId = Page.Request.QueryString["id"];
		if (!string.IsNullOrEmpty(dashboardId))
		{
			// Calculate the path to the dashboard file
			var dashboardPath = Server.MapPath(string.Format("Dashboards/{0}.mrt", dashboardId));
			if (File.Exists(dashboardPath))
			{
				// Load dashboard to the buffer
				var buffer = File.ReadAllBytes(dashboardPath);

				// Sent a dashboard to the client side as JSON data
				this.Response.ClearContent();
				this.Response.ClearHeaders();
				this.Response.ContentType = "application/json";
				this.Response.ContentEncoding = Encoding.UTF8;
				this.Response.AddHeader("Content-Length", buffer.Length.ToString());
				this.Response.BinaryWrite(buffer);
				this.Response.End();
			}
		}
	}
}

Then, create a new dashboard instance and load dashboard from server:

<script type="text/javascript">
	// Create a new dashboard instance and load dashboard from server
	var report = Stimulsoft.Report.StiReport.createNewDashboard();
	report.loadFile("GetDashboard.aspx?id=<%= DropDownList1.SelectedValue %>");

...

Finally, show dashboard in the viewer:

...

	// View dashboard in Viewer
	var options = new Stimulsoft.Viewer.StiViewerOptions();
	var viewer = new Stimulsoft.Viewer.StiViewer(options);
	viewer.dashboard = dashboard;
</script>
