    Just installed Q3 SP1 and it appears the ElementVisibility.Collapsed property for ListBoxItems is no longer functioning correctly.

    I use Collapsed to remove the item from selection without having to do another callback to the database.

    Is there any workarounds for the time being?

    Also the Rad Checkboxes seem to be very flaky when binding to a boolean via a Binding source as the ToggleState binding doesn't fire off to the underlying object.

    Hi Pawz,

    Thank you for writing.

    Please find the answers to your questions below:
    1. I confirm that collapsing items for virtualized RadListBox is not working correctly. This issue will be addressed in the upcoming release (Q1 2008). Meanwhile you may disable the virtualization by setting the Virtualized property of RadListBox to false.
      Thank you for bringing this issue to our attention. Your points are updated.
       
    2. I am not sure I completely understand your scenario. Could you give me a project that demonstrates what you describe or provide more information what control you are binding and what you expect to happen when changing ToggleState of some of its items.

    I hope this helps. If you need any further assistance, please contact me.

    Best wishes,
