Hi Chandan,

RadScheduler exposes two different types of context menus:

Appointment context menu

Time slot context menu

Additionally, you can conditionally set the ContextMenuID property to specify which context menu to open for a given appointment:

protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)
{
   e.Appointment.ContextMenuID = "SchedulerAppointmentContextMenu2";
}

I have also attached a simple demo of using context menus to copy/cut and paste appointments.

I'm also trying to figure this out. I need to be able to set the Appointment Context Menu text at runtime. Anyone?

Please look at this forum post, where the same question has already been answered.

@Hristo Valyavicharski,

 Please look at this forum post  where the OP states that the question was not answered.

Yes, at run-time you can select which of the context menus that were created in design time are to be attached to a given appointment. Check.

Matt, Chandan Kumar, and I are looking for the run-time capability to modfiy the context menu based on other criteria, such as is shown in this help topic for the TreeView control
   For instance I have a table of resources that is editable by the end user. I want the context menu to allow assignment of these resources.

  In pseudo code I would be looking for something like:

protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)

{

   RadSchedulerContextMenu menu = e.Appointment.ContextMenu;
   RadSchedulerContextMenuItem item = new RadSchedulerContextMenuItem("Display Text","Command Name","Command Args", hasChildren);
    RadSchedulerContextMenuItem node = menu.Items.FindByText("Home");
    node.Add(item); 
}

Is this possible?

Hi David,

Try this approach:

Define two context menus and make the second invisible:

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataDescriptionField="Description" DataEndField="End" DataKeyField="ID" DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="RecurrenceParentID" DataReminderField="Reminder"
    OnAppointmentDataBound="RadScheduler1_AppointmentDataBound" OnAppointmentCreated="RadScheduler1_AppointmentCreated"
    DataSourceID="sdsAppointments" DataStartField="Start" DataSubjectField="Subject">
    <AppointmentContextMenus>
        <telerik:RadSchedulerContextMenu ID="ContextMenu1" runat="server" OnClientItemOpening="OnClientItemOpening">
            <Items>
                <telerik:RadMenuItem Text="Copy">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadSchedulerContextMenu>
        <telerik:RadSchedulerContextMenu ID="ContextMenu2" runat="server" Visible="false">
        </telerik:RadSchedulerContextMenu>
    </AppointmentContextMenus>
</telerik:RadScheduler>

Handle the OnAppointmentCreated event:

protected void RadScheduler1_AppointmentCreated(object sender, AppointmentCreatedEventArgs e)
{
    if (e.Appointment.Subject == "test")
    {
        e.Appointment.ContextMenuID = ContextMenu1.ID;
    }
    else
    {
        e.Appointment.ContextMenuID = ContextMenu2.ID;
    }
}

I hope this helps.

Thank you for the response.

  It appears that the scheduler doesn't have the capabilities I am looking for and I will have to work around this limitation.

 Specific capabilities not included in the current version are:

 - Change TimeSlot context menus at run time using a RadScheduler1_TimeSlotCreated() event similar to your post directly above. As current, the RadScheduler only allows for one TimeSlot context menu that is built in design mode.

 - Add/change/update the menu items within a context menu during run time. Yes, you can create multiple different Appointment Context menus during design time and switch between them at run time. However you cannot dynamically add menu items to either an Appointment Context or TimeSlot Context menu.

      For example, appointments are assigned to a worker. The context menu has "Assign to Worker" as a main item. Through the 'AppointmentCreated' event, programatically grab a list of workers and add sub-items to the context menu.
    This dynamic capability exists in the RadMenu, as shown here: http://www.telerik.com/help/aspnet-ajax/menu-context-runtime.html

David,

This approach with adding items on the server is not suitable for this scenario. Here you want to have different context menus for every appointment. So this means you have to create separate context menu for every appointment. This is not recommended. Or if you have one menu it is not possible to change its items on the server because when the page is loaded all Scheduler's appointments will created. This what you could do is to add new menu items on the client. For example create one context menu and dynamically add/remove items in the OnClientAppointmentContextMenu event:

<telerik:RadScheduler
    ID="RadScheduler1"
    runat="server"
    DataDescriptionField="Description"
    DataEndField="End"
    DataKeyField="ID"
    DataRecurrenceField="RecurrenceRule"
    DataRecurrenceParentKeyField="RecurrenceParentID"
    OnClientAppointmentContextMenu="OnClientAppointmentContextMenu"
    DataReminderField="Reminder"
    OnAppointmentDataBound="RadScheduler1_AppointmentDataBound"
    OnAppointmentCreated="RadScheduler1_AppointmentCreated"
    DataSourceID="sdsAppointments"
    DataStartField="Start"
    DataSubjectField="Subject">
    <AppointmentContextMenus>
        <telerik:RadSchedulerContextMenu ID="ContextMenu1" runat="server" OnClientItemOpening="OnClientItemOpening">
            <Items>
                <telerik:RadMenuItem Text="Copy">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadSchedulerContextMenu>
    </AppointmentContextMenus>
</telerik:RadScheduler>

<script>
      var menu;

      function pageLoad() {
          menu = $find("<%= ContextMenu1.ClientID %>");
      }

      function OnClientAppointmentContextMenu(sender, args) {
          var rootItem = new Telerik.Web.UI.RadMenuItem();
          rootItem.set_text("New Root Item");
          menu.get_items().add(rootItem);
      }
  </script>
