How to change the backcolor for each date

[ranjani]

I need to set backcolor for each date ,how to set background color at run time for calendar control .

[Serrin]

I wanted to add to this, a feature request of sorts, is there any chance we are going to be seeing Special Days (like in the ASP.Net Ajax controls) in the Q1 or Q2 release? :)

Hi

It seems this link does no longer work:

http://demos.telerik.com/silverlight/#Calendar/SpecialDays

I would like to know more about the special days feature in Silverlight Calendar control.

Hi Valentijn,

You can find a brand new example following this link. It uses a custom style/template selectors applied to the calendar items.

Hi

Thank you for the link.
I have tried it, but i cannot see how i would assign events to the eventscollection from code behind. When i try to assign a name to the eventcollection resource, in code behind at runtime the eventscollection is not instantiated. If i try to create my own eventscollection in code behind and try to  assign in to the templateselector, the templateselector at runtime is also null.

If i don't use code behind it works, otherwise there seems to be no way.

How can i use the  templateselector from code behind?

Is there any way you can add days to the calendar that would show up in a different style immediately at runtime?

If you add the days to the eventscollection as in the example and you give it to the daystyleselector, the style will only be updated in the beginning when the calendar is rendered, but it will not update the style when you add events at runtime (for example if someone clicks a date in the calendar).

I need a way to let the user select and deselect dates in the calendar without using CTRL to select multiple dates. Also when a user clicks a date now, all the other days are deselected. Is there anyway to change this behavior? I thought the example using the eventscollection would help me, but the calendar is not update when adding or removing days to the eventsCollection.

Could someone point me in the right direction please?

Thank you

Hi ranjani,

All you have to do is update the DayTemplateSelector or StyleSelector with a new one. You can achieve that by setting it to null and then going back to the old one. You can put this code when a collection changing appears. Let us know if the approach is not clear enough.

Hello,

I'm having the same problem. I've done everything as described, but I'm not sure what you mean with the following:

All you have to do is update the DayTemplateSelector or StyleSelector with a new one. You can achieve that by setting it to null and then going back to the old one.

I've tried the following things:
1. In the codebehind: set the DayTemplateSelector of the Calendar control to null, and then back to the same DataTemplateSelector.
2. Remove the DataTemplateSelector from the resources and then add it again.
3. Call Calendar.UpdateLayout()
4. Create a new DataTemplateSelector in codebehind and set this as the DayTemplateSelector.

None of the approaches makes the calendar draw itself again with the correct daytemplates. Is there something I'm missing?

Thankx,

Hi

For me it was not working too, until i downloaded the latest hotfix. Just look and see if you have the latest version.

Hi Valentijn,

For me it seems to work when I set the Template in codebehind to null and than back to its old value. So something like this:

public void UpdateEventsCollection()
        {
            ObservableCollection<CalendarItemDto> newEventsCollection = new EventsCollection();
            newEventsCollection.AddRange(ViewModel.SelectedCalendarItems);
            var templateSelector = calendar.DayTemplateSelector as EventDayTemplateSelector;
            templateSelector.EventsCollection = newEventsCollection as EventsCollection;
            //trigger the SelectTemplate() of the changed TemplateSelector
            var oldTemplate = calendar.Template;
            calendar.Template = null;
            calendar.Template = oldTemplate;

        }

How do you trigger that the SelectTemplate of the DayTemplateSelector is fired again?

Thanks,
Sodi

Hello ranjani,

You can also download the 2010-Q3-2010 SP1 that will be launched later today and enjoy the new improvements regarding the other controls.
