ScheduleView Filtering

[Tarcisis]

Hi,

I want to do somenthing like you have in the example - ScheduleView - First Look. I will have several tabs (CustomViewDefinition), and a few of appointments. And when a click in a tab, i want to filter the appointments by the type of the game, ie, by the tab that i selected.
xaml:

<schedule:RadScheduleView Grid.Row="1"
                      x:Name="radScheduleView"
                                                     AppointmentsSource="{Binding Appointments}"
                                                     Template="{StaticResource RadScheduleViewControlTemplate}"
                                                     BorderBrush="{x:Null}"
                                                     Background="{StaticResource ScheduleViewBackground}">
</schedule:RadScheduleView>

MainPage.cs

private void FillScheduler()
{

    ScheduleViewModel cal = new ScheduleViewModel();
    radScheduleView.ViewDefinitions.AddRange(cal.GenerateViewsEncartes());

    ResourceTypeCollection collectionTypeEncartes = new ResourceTypeCollection();
    ResourceType encartes = new ResourceType("Games");
    encartes.Resources.AddRange(cal.GenerateResources());
    collectionTypeEncartes.Add(encartes);
    radScheduleView.ResourceTypesSource = collectionTypeEncartes;
    radScheduleView.DataContext = new ScheduleViewModel();

My doubt is in function :  private bool GroupFilterFunc(object groupName)!!
How do i apply the filter!!

Thanks

Hello Tarcisis,

You should create a different GroupFilter for every ViewDefinition. I've attached a simple project based on your code to demonstrate the approach, please download it and examine it.

Hi,
Thanks for the answer!

You created distinct GroupFilter for each view.
How can i build that GroupFilters dynamically instead of create  private Func<object, bool> for each one?!? (Supose that comming from a DB)
Thanks

[Tarcisis]

For example,

The types of games are coming from DB, so, i can´t create that filters "Hardcoded" , i need to create them in runtime.
Do you have any ideia?

Thanks

[Tarcisis]

That´s why i used only one function...

        private bool GroupFilterFunc(object groupName)
        {

            IResource resource = groupName as IResource;
            return resource == null ? true : resource.ResourceName == **************;

        }

the "**************" means that here i want to know in which CustomViewDefinition did I click.

Thanks

Hello Tarcisis,

You're right that having different GroupFilter functions is not the best solution.  The other option I can suggest is to use an additional parameter in GroupFilterFunc for the different views. I've attached the modified project to demonstrate the approach. Please download it and give it a try.

All the best,

Thanks!!
That´s it!!

Hi again,

One last question!
It is possible to use MonthViewDefinition instead of CustomViewDefinition??
I need to use the MonthViewDefinition , but with this kind of view i can´t add GroupDescriptions, and so it doesn´t filter!

Thanks.

[Yana]

Hello Tarcisis,

I suggest to set the GroupDescriptions to the ScheduleView, in this way you can use MonthViewDefinition with GroupFilter without a problem.

 You can find the modified project attached.

Kind regards,
