Thanks Andrew,

Sorry i am new to .net and WPF.

I have trie it by setting

dataManager.Settings.LogicalDayOffset = new System.TimeSpan(6, 0, 0);

bu i keep getting exception 'Object reference not set to an instance of an object.'

Hope you can help if i am doing something very stupid.

Hi Andrew,

I am trying to achieve a similar thing. I need to store Appointment Type info in each TimeSlot. Is there a way to set DataItem for each TimeSlot?

Hi,

Can you shed some light on how I can achieve this with "creating some attached propertes and setting that in sustom style? I have downloaded the source code, but a alot of the classes are marked as internal.

The source isn't really going to help you with creating attached properties; that is just general WPF functionality. What I was describing was an attached property so that you could set some custom information on the timeslot and then in theory you would retemplate the timeslot elements to make use of that information however you needed.

In the simple project attached I'm just evaluating the start/end to see if it intersects with lunch time (in this case a fixed time range). So for that I have a simple enum that I will set on the timeslot elements:

 public enum TimeslotType
 {
  NonWorkingTime,
  WorkingTime,
  LunchTime,
 }

You would define an attached property that will hold whatever information you need to have access to in the element.

  #region TimeslotType

  public static readonly DependencyProperty TimeslotTypeProperty =
   DependencyProperty.RegisterAttached("TimeslotType", typeof(TimeslotType), typeof(ScheduleData),
    new FrameworkPropertyMetadata((TimeslotType)TimeslotType.WorkingTime));
  public static TimeslotType GetTimeslotType(DependencyObject d)
  {
   return (TimeslotType)d.GetValue(TimeslotTypeProperty);
  }
  public static void SetTimeslotType(DependencyObject d, TimeslotType value)
  {
   d.SetValue(TimeslotTypeProperty, value);
  }
  #endregion //TimeslotType

Now since you likely want to use the Start/End of the timeslot to make your determine you would probably create a multibinding to get the state information so you'll need a multivalueconverter that will take the information and return the state information that you want to attach. Note: As with any multibinding you'll want to bind to every property whose change could affect the result because the multibinding will only be evaluated whenever the value of one of the properties in the binding have been changed.

 public class TimeslotTypeValueConverter : IMultiValueConverter
 {
  public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
  {
   if (values == null || values.Length != 4)
    return DependencyProperty.UnsetValue;

   if (values[0] is ScheduleData == false ||
    values[1] is DateTime == false ||
    values[2] is DateTime == false ||
    values[3] is Boolean == false)
    return DependencyProperty.UnsetValue;
   ScheduleData data = values[0] as ScheduleData;
   DateTime startTime = (DateTime)values[1];
   DateTime endTime = (DateTime)values[2];
   bool isWorkingHour = (bool)values[3];
   return data.GetTimeslotType(startTime, endTime, isWorkingHour);
  }
  public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
  {
   return new object[] { DependencyProperty.UnsetValue };
  }
 }

Then you need a multibinding that will use that converter. You could set the multibinding on something inside your custom TimeslotPresenter template or you could do it in your style. I chose the latter:

 <Window.Resources>
  <local:TimeslotTypeValueConverter x:Key="timeslotConverter" />
  <Style TargetType="igPrim:TimeslotPresenter">
   <Setter Property="local:ScheduleData.TimeslotType">
    <Setter.Value>
     <MultiBinding Converter="{StaticResource timeslotConverter}">
      <Binding Path="DataContext" RelativeSource="{RelativeSource AncestorType={x:Type Window}}" />
      <Binding Path="Start" RelativeSource="{RelativeSource Self}" />
      <Binding Path="End" RelativeSource="{RelativeSource Self}" />
      <Binding Path="IsWorkingHour" RelativeSource="{RelativeSource Self}" />
     </MultiBinding>
    </Setter.Value>
   </Setter>
  </Style>
 </Window.Resources>

Then you need a custom template that will make use of that information. In this case I'll just change the Background when its lunch time and the timeslot is not selected. Note: You can find the default styles/templates in the DefaultStyles directory (e.g. in the C:\Program Files\Infragistics\NetAdvantage 2011.1\WPF\DefaultStyles\Schedule directory) and use that as the basis for your custom templates/styles.

   <Setter Property="Template">
    <Setter.Value>
     <ControlTemplate TargetType="igPrim:TimeslotPresenter">
      <Grid>
       <Border x:Name="Border"
        BorderBrush="{TemplateBinding ComputedBorderBrush}"
        BorderThickness="{Binding Path=Orientation, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource tsOrientationToThicknessConverter}}"
        Background="{TemplateBinding ComputedBackground}"
        Padding="{TemplateBinding Padding}"
        igPrim:XamlHelper.SnapsToDevicePixels="True">
       </Border>
       <Border x:Name="DayBorder"
        BorderBrush="{TemplateBinding DayBorderBrush}"
        BorderThickness="{TemplateBinding DayBorderThickness}"
        Visibility="{TemplateBinding DayBorderVisibility}"
        igPrim:XamlHelper.SnapsToDevicePixels="True">
       </Border>
      </Grid>
      <ControlTemplate.Triggers>
       <MultiTrigger>
        <MultiTrigger.Conditions>
         <Condition Property="IsSelected" Value="False" />
         <Condition Property="local:ScheduleData.TimeslotType" Value="LunchTime" />
        </MultiTrigger.Conditions>
        <Setter TargetName="Border" Property="Background" Value="DarkGray" />
       </MultiTrigger>
      </ControlTemplate.Triggers>
     </ControlTemplate>
    </Setter.Value>
   </Setter>

Thanks Andrew,

That sample app was very useful. It got me started thinking on how to go about implementing my requirements.

Hi Stefan,

I actually found the way to do this. All I needed is to get the list of timeslots and update binding. That was all.

Thanks for you help

Hello Steven,

it seems like that I am missing something in your scenario, so feel free to modify the sample I sent you, so it reproduces your behavior and send it back to me for further investigation.

Looking forward for your reply.

Hi Stefan,

Andrew's example is about TimeSlots not Appointments. I was asking about how to trigger the TimeSlot to refresh.

Does my question make sense?

Best Regards,

Steven

Hello Steven,

I have modified the sample Andrew uploaded, so now there is a Button which changes the Properties of one of the Appointments and everything seems to update properly on my side. If the sample doesn’t satisfies all your needs feel free to modify it, so it reproduces your behavior and send it back to me for further investigation.

Looking forward for your reply.

Hi Stefan,

What I meant is that the sample given works fine when the timeslot gets created it binds to the custom properties.

But what if the custom properties changes and we need to time slot to rebind?
