Determine the type of SelectedSlot

[Brendan]

Hi.

Is there a way to determine the type of the SelectedSlot property on the RadScheduleView control?

I've got a DayView definition setup on my ScheduleView.

I've created a class called LunchSlot inherited from the base type of Slot. This class has some extra properties associated with it.

When I'm loading the appointment data for the Schedule control I also load the lunch definition for a resource, for example Lunch has a recurrence pattern from 1pm - 2pm every day. So I create my LunchSlot object with this recurrence pattern, add it to a collection and bind it to the SpecialSlotsSource of the ScheduleView.

The Lunch slots show up in the scheduleview all ok with the default gray colour.

During the AppointmentCreating event I want to determine if the SelectedSlot is now a LunchSlot or just a regular Slot. Is there any way to do this?

If I double click on a slot between 1pm - 2pm, the SelectedSlot property only seems to return a type of Slot and I have no way to determine if this was a Special slot or just a normal slot.

I still want the user to be able to create an appointment on a special slot (as it's not marked as ReadOnly), but I want to prompt the user for confirmation that they are about to create an appointment on a special slot before proceeding.

Hello Brendan,

You cannot directly get the custom slot in AppointmentCreating event handler,  I would suggest to use the Slot's IntersectsWith method to find the correct slot.

I've attached a simple example to demonstrate the needed approach, please download the attachment and give it a try.  Note how Copy and CopyFrom methods of the LunchSlot class are implemented.

Kind regards,

Hi Yana,

Thanks for the sample, however using the example, no matter what slot I double click on now it thinks that it is of the type LunchSlot.
I added this line to the example:

if (lunchSlot != null)
{
    var customProp = lunchSlot.CustomProperty;
    MessageBox.Show("Lunch Slot Selected");
}

And double clicking on any slot will show the message box, even if it's not a special slot.

Hi Brendan,

You are right, I've found the reason for this issue but will need some additional time to fix it. I will write here as soon as it's ready.

The workaround is:
Create specialslotStyleSelector like this:

public class SpecialSlotStyleSelector : ScheduleViewStyleSelector

{

 

public Style OtherStyle { get; set; }

 

public override Style SelectStyle(object item, DependencyObject container, ViewDefinitionBase activeViewDefinition)

{

 

if (item is SlotScheduler)

{

 

SlotScheduler slot = item as SlotScheduler;

container.SetValue(

 

HighlightItem.TagProperty, slot); //Set on tag of HighlightItem the custom Special slot

}

 

if (OtherStyle != null)

 

return OtherStyle;

}

 

return base.SelectStyle(item, container, activeViewDefinition);

}

into XAML create this resource so on tag of border we have the custom special slot :)
<Style x:Key="OtherStyle1" TargetType="telerik:HighlightItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Border Background="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background}" MouseLeftButtonDown="Border_MouseLeftButtonDown" Tag="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Tag}"  >
                            <Border.ToolTip>
                                <TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ToolTip}"/>
                            </Border.ToolTip>

                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
