Refresh ScheduleView after adding resources in code behind

[Jeffrey]

Hello,

I'm evaluating this control to look if it fills my needs, because I'm building an application where I need a schedule component.

In code behind i'm adding resources to a ResourceType in my ResourceTypeCollection, but the new resource is not displayed in the ScheduleView. When I navigate to another day then the new Resource appears.

   ResourceType.Resources.Add(new Resource { ResourceName = "Phil Collins" });

Now I tried the following and this works, but I can't imagine that this is a proper way to make it work.

   ResourceType.Resources.Add(new Resource { ResourceName = "Phil Collins" });
   ResourceTypeCollection.Remove(ResourceType);
   ResourceTypeCollection.Add(ResourceType);

ResourceTypeCollection is an ObservableCollection<ResourceType>() and when I Add or Remove a Resource the ScheduleView is updated, but isn't there a way to update the ScheduleView when I just add Resources without removing / adding ResourceTypes from / to the ResourceTypeCollection?

Thanks in advance!

Best regards,
Jeffrey

Hi Jeffrey,

You are correct, this is the right way to add resources to a resource type at runtime. We intentionally do not listen for changes in the Resources collection of a ResourceType (actually all of its properties) because of performance considerations, as we will have to reset the whole RadScheduleView once a Resource is added, and if you are adding many resources, we will have to do a reset every time.

This solution does not cause the ScheduleView to refresh the resources.  i'm using a usercontrol to style the resource headers and they are not refreshing when the ResourceTypeCollection is set or when an item in the collection is changed. my solution involves creating a new instance of the control, but this is not an option in all instances.

Hi,

Regarding performance, what is the best method to use of the two described in the link abowe?

I use the remove/add of the resource type but it is taking a couple of seconds for me, when I have 200+ resources with 600+ appointments.
Would I gain anything by implementing the group filter instead?

Hi Håkan,

I guess that implementing Group Filter should be faster, but it depends on the specific case as well.  I have attached a sample project with 200 resources and group filter, so you could check whether this solution is suitable for your case.
