RadCycleHubTile -- which element is active?

[Eugene]

Hey guys:

So I've got a RadCycleHubTile control bound to an ObservableCollection, and set to not cycle randomly. I need to know which of the elements in the ObservableCollection is currently being displayed. Is there a way for me to do that?

Thanks!

P.S. How come HubTile isn't derived from an ItemsControl? Then we'd get a SelectedItem property, which would be very much in line with what the control seems to do... just curious.

Ok, I figured out one way to do this. Namely, to manually find the visualchild of the type I expect to be embedded within the RadCycleHubTile, and then get to its DataContext. 

The problem is if I remove the data context of the item being displayed from ItemsSource (and even if I reset ItemsSource by setting it to null then back to the modified list), the item displayed continues being displayed. 

Is there a way for me to force the control to change the displayed item to the next item in the ItemsSource array?

Hi Eugene,

I am afraid that this is not the intended usage of a hub tile. A tile does not support the concept of selection. It is more like a button that displays some dynamic content. It is not a selector by design.

Currently there is no supported way to achieve the desired behavior with any hub tile.

Thanks for the feedback.
We will consider whether there is something we can do on our side to support this scenario.
Please write again if you have more questions.

Hi Viktor:

Thanks for your response. So to give you a bit more context, I'm essentially trying to allow the user to drag one of the displayed tiles out into a different location. Is there a different control I should use?

Is there a way for me to get to the source code of RadCycleHubTile? Then I can just modify it to do what I want...

Thanks!

Hello Eugene,

In the other thread about the tiles you mentioned that you downloaded the source. Feel free to ask us if you need guidance with its modification or if you need assistance with something else.

Yup, should be good now. Trying to get just the source of the CycleHubControl to build without pulling the rest of the sources and xaml themes into the project is taking a bit of time, but I think I can manage. :)

Awesome, we're on standby if you need help :).
