Disable Holidays and Weekends

[Deepak]

Hi,
I need to disable the Weekends and Holidays while selecting the date.In order to achieve this I tried using following code.

<telerik:RadDatePicker Width="150" Margin="8 5" DateSelectionMode="Day" Name="dtFirstPHDate" SelectedValue="{Binding mFirstPHDate, Mode=TwoWay}" >

                                <telerik:RadDatePicker.DayTemplateSelector>

                                    <DateTemplate:CustomTemplateSelector>

                                        <DateTemplate:CustomTemplateSelector.DefaultTemplate>

                                            <DataTemplate>

                                                <TextBlock Text="{Binding dtStartDate, Mode=TwoWay}"></TextBlock>

                                            </DataTemplate>

                                        </DateTemplate:CustomTemplateSelector.DefaultTemplate>

                                             

                                    </DateTemplate:CustomTemplateSelector>

                                </telerik:RadDatePicker.DayTemplateSelector>

                            </telerik:RadDatePicker>

public class CustomTemplateSelector : DataTemplateSelector
{
   public override DataTemplate SelectTemplate(object item, DependencyObject container)
   {
       CalendarButtonContent content = item as CalendarButtonContent;
       if (content != null)
       {
           if (content.Date.DayOfWeek == DayOfWeek.Saturday || content.Date.DayOfWeek == DayOfWeek.Sunday||holidaysList.Contains(content.Date))
           {
               content.IsEnabled = false;
           }
       }
       return DefaultTemplate;
   }
   public DataTemplate DefaultTemplate
   {
       get;
       set;
   }
}

But still it is not working.
FYI
DateTime Picker Version:2010.2.0714.1040 (RadControls for Silverlight Q2 2010).Please help me to resolve this issue.

Hi Deepak,

Your code should look similar to the following one:

<Setter Property="DayTemplateSelector">
                        <Setter.Value>
                            <local:CustomTemplateSelector>
                                <local:CustomTemplateSelector.DefaultTemplate>
                                    <DataTemplate>
                                        <TextBlock Text="{Binding Text}" Foreground="Red" />
                                    </DataTemplate>
                                </local:CustomTemplateSelector.DefaultTemplate>
                            </local:CustomTemplateSelector>
                        </Setter.Value>
                    </Setter>

Let us know if you are still experiencing a problem.

Hi,
I have download your sample and used the telerik.windows.controls.input dll of version 2013.3.1316.1050. And noticed problems when swithing from febuary to march and other months. the dates picked is totally off compared to the values in the date picker text box.

I removed the daytemplate selector and it works properly just that the weekends are now reselectable. So i figured the custom template selector is causing problems

Hi Lim,

We are not aware of such problems. I've tried to reproduce the problem you've mentioned, but unfortunately I couldn't. Please check the attached sample project which demonstrates how to disable the weekends and the holidays.

If you have any other issues considering this case, please don't hesitate to contact us again.

[Lim]

Also could you please give me a silverlight sample?

Thanks

Hello Lim,

I've created a Silverlight version of the sample project which you could find attached. 
In our forum are allowed only images for security reasons. If you like to attach a sample project you need to register and then to open a support ticket. You could find more about our support plans here.

[Lim]

did you look at the image i have attached? Are you able to replicate the issue with the image?

[Lim]

Hi I am able to fix it using the sample provided.

However, it couldnt work with the approach posted here:
http://www.telerik.com/forums/disable-all-weekdays-and-all-weekends

Have you guys included documentation on disabling weekdays? it would be best to include it there so we can always refer to the updated document.

[Kalin]

Hello Lim,

If you need to disable the weekends in addition to solution Ventzi has provided you - you will need to add the following if statement in the begging of the SelectTemplate method:

public override System.Windows.DataTemplate SelectTemplate(object item, System.Windows.DependencyObject container)
{
    var content = item as CalendarButtonContent;

    if ((content.Date.DayOfWeek == DayOfWeek.Saturday || content.Date.DayOfWeek == DayOfWeek.Sunday) && content.ButtonType == CalendarButtonType.Date)
    {
        content.IsEnabled = false;
    }
   ....
}

Thanks for the feedback about the documentation, we will consider including article about the TemplateSelectors in the Calendar of the DateTimePicker. You can also check the BlackoutDates article which demonstrate how to disable particular dates from the DateTimePicker calendar.

Hope this helps.
