Hi Srinivas,

Thank you for writing.

As far as I understand, you want to navigate through the resources of RadScheduler by using a drop-down list. The following code snippet demonstrates how to achieve this:

public Form1()
{
    InitializeComponent();
    this.radScheduler1.ActiveView.ResourcesPerView = 1;
    this.radDropDownList1.DataSource = this.radScheduler1.Resources;
    this.radDropDownList1.DisplayMember = "Name";
    this.radDropDownList1.SelectedIndexChanged += new Telerik.WinControls.UI.Data.PositionChangedEventHandler(radDropDownList1_SelectedIndexChanged);
}

void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    if (this.radDropDownList1.SelectedIndex != -1)
    {
        SchedulerDayViewGroupedByResourceElement dayView = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;
        SchedulerMonthViewGroupedByResourceElement monthView = this.radScheduler1.SchedulerElement.ViewElement as SchedulerMonthViewGroupedByResourceElement;
        TimelineGroupingByResourcesElement timelineView = this.radScheduler1.SchedulerElement.ViewElement as TimelineGroupingByResourcesElement;
        if(dayView!=null)
        {
            dayView.NavigateToResource(this.radDropDownList1.SelectedIndex);
        }
        if (monthView != null)
        {
            monthView.NavigateToResource(this.radDropDownList1.SelectedIndex);
        }
        if (timelineView != null)
        {
            timelineView.NavigateToResource(this.radDropDownList1.SelectedIndex);
        }
    }
}

I hope this will help you. Do not hesitate to write back if you have any further questions.

Hello Srinivas,

Thank you for clarifying your requirements.

You can use the Visibility property of the appointment to display only appointments that belong to the selected resource. The delete and update operations should work normally without any additional code. To insert appointments correctly, you need to handle the Appointment.CollectionChanging event to listen for new appointments and set their ResourceId. The following code snippet demonstrates this:

public partial class Form1 : Form
 {
     Color[] colors = new Color[]{Color.LightBlue, Color.LightGreen, Color.LightYellow,
Color.Red, Color.Orange, Color.Pink, Color.Purple, Color.Peru, Color.PowderBlue};

     string[] names = new string[]{"Alan Smith", "Anne Dodsworth",
"Boyan Mastoni", "Richard Duncan", "Maria Shnaider"};

     public Form1()
     {
         InitializeComponent();

         for (int i = 0; i < names.Length; i++)
         {
             Resource resource = new Resource();
             resource.Id = new EventId(i);
             resource.Name = names[i];
             resource.Color = colors[i];

             this.radScheduler1.Resources.Add(resource);
         }

         this.radDropDownList1.DataSource = this.radScheduler1.Resources;

         this.radDropDownList1.DisplayMember = "Name";
         this.radDropDownList1.ValueMember = "Id";
         this.radDropDownList1.SelectedIndexChanged += new Telerik.WinControls.UI.Data.PositionChangedEventHandler(radDropDownList1_SelectedIndexChanged);
         this.radScheduler1.Appointments.CollectionChanging += new Telerik.WinControls.Data.NotifyCollectionChangingEventHandler(Appointments_CollectionChanging);
     }

     void Appointments_CollectionChanging(object sender, Telerik.WinControls.Data.NotifyCollectionChangingEventArgs e)
     {
         if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Add && e.NewItems != null)
         {
             foreach (Appointment app in e.NewItems)
             {
                 app.ResourceId = this.radDropDownList1.SelectedValue as EventId;
             }
         }

         UpdateAppointmentVisibility();
     }

     void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
     {
         UpdateAppointmentVisibility();
     }

     private void UpdateAppointmentVisibility()
     {
         foreach (Appointment app in this.radScheduler1.Appointments)
         {
             if (app.ResourceId == this.radDropDownList1.SelectedValue)
             {
                 app.Visible = true;
             }
             else
             {
                 app.Visible = false;
             }
         }
     }
 }

hello


1)your code is working fine when i creatging a new apointment what about the appointments already exist ! which has no resourcid for already exists appointments


2) here all resources are displaying in EditAppointment
 3)please on editAppointment window i want to display raddropdown selected item in REsources combo box of ... ok

[Ivan Todorov]

Hello Srinivas,

In my opinion, the appointments that do not have an associated resource should be displayed no matter which resource is selected. To achieve this, you just need to check if the appointment's ResourceId property is null:

private void UpdateAppointmentVisibility()
{
    foreach (Appointment app in this.radScheduler1.Appointments)
    {
        if (app.ResourceId == this.radDropDownList1.SelectedValue || app.ResourceId == null)
        {
            app.Visible = true;
        }
        else
        {
            app.Visible = false;
        }
    }
}

If this differs from your requirements, please let me know and I will assist you in achieving them.

In case you have any further questions, do not hesitate to ask.
