Binding DependencyProperty when invisible?

I have a WPF window that contains a Telerik RadPaneGroup, and in it I have a RadPanes:

<telerik:RadPaneGroup>
    <telerik:RadPane
        x:Name="ticketMapPane"
        Header="Map"
        CanUserPin="False"
        CanFloat="{Binding preferencesProperties.canFloatPanes}"
        IsHidden="{Binding Path=viewModel.stickyProperties.mapPaneVisible, RelativeSource={RelativeSource AncestorType=KtWpf:KorWindow}, Mode=TwoWay, Converter={StaticResource boolInverterConverter}}"
        telerik:RadDocking.SerializationTag="ticketMapPane"
    >
    <local:TicketMap
        x:Name="ticketMap"
        ticketMapType="{Binding RelativeSource={RelativeSource AncestorType=KtWpf:KorWindow}, Path=viewModel.preferencesProperties.ticketMapType}"
        />
    </telerik:RadPane>
</telerik:RadPaneGroup>

The ticketMapPane.IsHidden property is bound to the negation of stickyProperties.mapPaneVisible, so if mapPaneVisible is true, IsHidden is false, and the pane is displayed.

If mapPaneVisible is true on startup, ticketMapPane is visible, and ticketMap.ticketMapType is bound correctly to preferencesProperties.ticketMapType, and all is well with the world.

If I then manipulate the UI control that sets stickyProperties.mapPaneVisible to false the pane becomes invisible, if I set it to true the pane becomes visible again, and ticketMapType is bound correctly through it all.

But if stickyProperties.mapPaneVisible is false on startup, ticketMapPane is hidden, and ticketMapType doesn't seem to be bound.
I have a change handler on the ticketMapType property. It's called, when the ticketMapPane is visible on startup, and it is not, when it is not:

public partial class TicketMap : KorUserControl
{
    public TicketMapType ticketMapType
    {
        get { return (TicketMapType)GetValue(ticketMapTypeProperty); }
        set { SetValue(ticketMapTypeProperty, value); }
    }
    public static readonly DependencyProperty ticketMapTypeProperty =
        DependencyProperty.Register("ticketMapType", typeof(TicketMapType), typeof(TicketMap),
        new PropertyMetadata(new PropertyChangedCallback(ticketMapTypePropertyChanged)));
    private static void ticketMapTypePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var ticketMap = d as TicketMap;
        if (ticketMap != null && e.NewValue is TicketMapType)
        {
            var ticketMapType = (TicketMapType) e.NewValue;
            ticketMap.setTicketMapType(ticketMapType);
        }
    }
    [...]
}

So what is happening is that if the pane is hidden on startup, when I make it visible the TicketMap.ticketMapType contains the default value, and not the value that it was supposed to be bound to. If the pane is visible on startup, everything binds correctly.

So, the question - how do I get this to work?

 I can see two possibilities:

  1. I get the binding to connect even though the pane is invisible, or
  2. I get the binding to connect when the pane is made visible.

Any ideas as to how to do either?

Scheduleview not rending appointments under 24 hours

I'm trying to render appointments in the scheduleview but only entire days are rendered as shown in attachment.

I'm using the Scheduleview like this 

<telerik:RadScheduleView x:Name="MainSchedule" Grid.Column="1" Margin="2" NavigationHeaderVisibility="Collapsed" AppointmentsSource="{Binding Appointments}"
                                                    ResourceTypesSource="{Binding ResourceTypes}" SelectedAppointment="{Binding SelectedAppointment, Mode=TwoWay}" MouseDoubleClick="MainSchedule_MouseDoubleClick"
                                                    CurrentDate="{Binding DateStart}" GroupHeaderContentTemplateSelector="{StaticResource GroupSelector}" AppointmentItemContentTemplate="{StaticResource AppointmentTemplate}">
                               <telerik:RadScheduleView.GroupDescriptionsSource>
                                   <scheduleView:GroupDescriptionCollection>
                                       <scheduleView:ResourceGroupDescription ResourceType="Staff" />
                                   </scheduleView:GroupDescriptionCollection>
                               </telerik:RadScheduleView.GroupDescriptionsSource>
                               <telerik:RadScheduleView.ViewDefinitions>
                                   <telerik:TimelineViewDefinition TimerulerGroupStringFormat="{}{0:dd MMM}" TimerulerMajorTickStringFormat="{}{0:HH}" TimerulerMinorTickStringFormat="{}{0:HH}"/>
                               </telerik:RadScheduleView.ViewDefinitions>
                           </telerik:RadScheduleView>

 

private void LoadHolidays()
       {
           if (_holidayResource != null)
           {
               Appointments.Clear();
               var holidays = _dataService.GetManager().TblDatStaffTime.Where(st => st.TblLstActivity.ActivityType == "Holiday" && st.RealStart >= this.CurrentView.MainSchedule.CurrentDate.FirstDayOfMonth() &&
                                   st.RealEnd < this.CurrentView.MainSchedule.CurrentDate.LastDayOfMonth()).Execute();
 
               foreach (TblDatStaffTime item in holidays)
               {
                   var appt = new HolidayAppointment(item);
 
                   if (_holidayResource.Where(c => c.Key == item.StaffID.ToString()).Count() > 0)
                   {
                       appt.Resources.Add(_holidayResource[item.StaffID.ToString()]);
                       this.Appointments.Add(appt);
                   }
               }
 
               var countApp = this.CurrentView.MainSchedule.AppointmentsSource;
           }
       }

 

public class HolidayAppointment : Appointment
   {
       private bool isReadOnly;
       public TblDatStaffTime Holiday { get; set; }
 
       public HolidayAppointment(TblDatStaffTime holiday)
       {
           this.Holiday = holiday;
       }
 
       public bool IsReadOnly
       {
           get { return this.Storage<HolidayAppointment>().isReadOnly; }
           set
           {
               var storage = this.Storage<HolidayAppointment>();
               if (storage.isReadOnly != value)
               {
                   storage.isReadOnly = value;
                   this.OnPropertyChanged(() => this.IsReadOnly);
               }
           }
       }
 
       public override string Subject
       {
           get { return Holiday.TblLstActivity.ShortName; }
       }
 
       public SolidColorBrush HolidayBrush
       {
           get { return new SolidColorBrush(StringExtensions.HexStringToColor(Holiday.TblLstActivity.Color)); }
       }
 
       public override DateTime Start
       {
           get { return this.Holiday.RealStart; }
           set
           {
               base.Start = this.Holiday.RealStart;
               this.OnPropertyChanged(() => this.Start);
           }
       }
 
       public override DateTime End
       {
           get { return this.Holiday.RealEnd; }
           set
           {
               base.End = this.Holiday.RealEnd;
               this.OnPropertyChanged(() => this.End);
           }
       }
 
       private string GetTranslation()
       {
           string result = string.Empty;
 
           switch (IdentityCSD.Language)
           {
               case IdentityCSD.Languages.EN:
                   result = Holiday.TblLstActivity.DescEN;
                   break;
               case IdentityCSD.Languages.NL:
                   result = Holiday.TblLstActivity.DescNL;
                   break;
               case IdentityCSD.Languages.FR:
                   result = Holiday.TblLstActivity.DescFR;
                   break;
               case IdentityCSD.Languages.GE:
                   result = Holiday.TblLstActivity.DescGE;
                   break;
               default:
                   result = Holiday.TblLstActivity.DescLC;
                   break;
           }
 
           return result;
       }
   }

So that appoinments that are showing are 24 hours long. And those which are not showing are less. Anyone got a solution for this ?

Disable scrolling in Backstage
Hi,

I try to disable scrolling in RadRibbonBackstage.

I know that changing ControlTemplate and deleting Scrollviewer works.

But this solution is not compatible with switching theme at runtime.

Please, is there any solution ?

Visual Studio designer error- Object does not match target type

In Visual Studio 2012 I have problem with a RadGridView using a project binding source.  It happened after making a change in my code and recompiling.

Sometimes the problem will magically go away after clicking on a different control and then clicking on the grid again. Other times I have to completely close VS and reopen it.

Hopefully someone has suggestions on how to fix it.

Put barcode on image
I would like to attach a Code128 barcode on the corner of a existing image ( jpeg, png, tiff) programmatically, and then print it out through program. But so far as I go through the telerik document and demo, I couldn't find a proper way to put the barcode on the image. Is there any way to do so ? I would really appreciate if anyone would give me any suggestion.
