using System.Web.Routing;
using DevExpress.DashboardWeb;
using DevExpress.DashboardWeb.Mvc;
using System.Web.Hosting;
using DevExpress.DataAccess.Excel;
using DevExpress.DashboardCommon;

namespace DashboardMVC {
    public static class DashboardConfig {
        public static void RegisterService(RouteCollection routes) {

            DashboardFileStorage dashboardFileStorage = new DashboardFileStorage("~/App_Data/Dashboards");
            DataSourceInMemoryStorage dataSourceStorage = new DataSourceInMemoryStorage();
            // Registers an Excel data source.
            DashboardExcelDataSource excelDataSource = new DashboardExcelDataSource("Excel Data Source");
            excelDataSource.ConnectionName = "Excel Data Source ID";
            excelDataSource.SourceOptions = new ExcelSourceOptions(new ExcelWorksheetSettings("Sheet1"));
            dataSourceStorage.RegisterDataSource("excelDataSource", excelDataSource.SaveToXml());
            DashboardConfigurator.Default.ConfigureDataConnection += Configurator_ConfigureDataConnection;
         private static void Configurator_ConfigureDataConnection(object sender, ConfigureDataConnectionWebEventArgs e) {
            if (e.ConnectionName == "Excel Data Source ID") {
                ExcelDataSourceConnectionParameters excelParams = new ExcelDataSourceConnectionParameters(HostingEnvironment.MapPath(@"~/App_Data/Sales.xlsx"));
                e.ConnectionParameters = excelParams;
