To access the control in code, create a View Controller and override its OnActivated method. Set the Controller’s ViewController.TargetViewType property to ListView. This way the Controller is activated for List Views only.

ASP.NET Core Blazor

File:
YourApplicationName.Blazor.Server\Controllers\SchedulerController.cs

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Scheduler.Blazor;
using DevExpress.ExpressApp.Scheduler.Blazor.Editors;
using DevExpress.Persistent.Base.General;

namespace YourApplicationName.Module.Controllers {
    public partial class SchedulerController : ObjectViewController<ListView, IEvent> {
        protected override void OnViewControlsCreated() {
            base.OnViewControlsCreated();
            if(View.Editor is SchedulerListEditor schedulerListEditor) {
                // Obtain an instance of the DxSchedulerModel type.
                schedulerListEditor.SchedulerModel.ActiveViewType = DevExpress.Blazor.SchedulerViewType.WorkWeek;
            }
        }
    }
}

Windows Forms

File:
YourApplicationName.Win\Controllers\SchedulerController.cs

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Scheduler.Win;
using DevExpress.Persistent.Base.General;
using DevExpress.XtraScheduler;
namespace YourApplicationName.Module.Controllers {
    public partial class SchedulerController : ObjectViewController<ListView, IEvent> {
        protected override void OnViewControlsCreated() {
            base.OnViewControlsCreated();
            if(View.Editor is SchedulerListEditor schedulerListEditor) {
                SchedulerControl scheduler = schedulerListEditor.SchedulerControl;
            }
        }
    }
}

Note

If the CrossThreadFailure error occurs when you handle SchedulerControl events, set the control’s SchedulerOptionsBehavior.UseAsyncMode option to false.

ASP.NET Web Forms

File:
MySolution.Module.Web\Controllers\SchedulerController.cs

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Scheduler.Web;
using DevExpress.Persistent.Base.General;
using DevExpress.Web.ASPxScheduler;

namespace YourApplicationName.Module.Controllers {
    public partial class SchedulerController : ObjectViewController<ListView, IEvent> {
        //...
        protected override void OnViewControlsCreated() {
            base.OnViewControlsCreated();
            if(View.Editor is ASPxSchedulerListEditor schedulerListEditor) {
                ASPxScheduler scheduler = schedulerListEditor.SchedulerControl;
            }
        }
    }
}
