RadDocking Compass remain visible
Dear Support!

I am using RadControls_for_WPF_2011_3_1116_Dev.
When I drag the Pane, the Compass remain visible, or sometimes I am getting a NullReferenceException (refer attachment).

Please let me know how to resolve the issue.

GanttView and custom item templates
Working through some sample code with GanttView, and I'm wondering if I am able to do any of the following either by some level of re-templating or via support that I haven't yet discovered with the control's OM:

1. In-line labeling of milestones or summary tasks. I believe the control will apply a label inline with a task (shows up in the interior of the task timeline graphic). Can I do something similar for milestone diamonds and summary tasks?

2. Rollup views. Is there a way that I can show, for example, milestones or tasks laid on top of/inline with a summary task? E.g, can I get the same 'task rollup' functionality that we have today in Microsoft Project?

3. In general, is there some sample XAML that demonstrates changing the appearance of tasks/milestones/summary tasks?

Thanks!

BusyIndicator when DropDownButton DropDownContent is open
I am having difficulties getting a busy indicator to show when a dropDown button is clicked.  The dropDown buttons are created dynamically from a collection and a command is attached to each button.  When the button is clicked, the command executes a specific service call to get the content of the dropdown.  However, this service call may take a while to execute and I would like to show a busyindicator when this is happening.  I have tried adding the busy indicator to the dropdown content with the listbox that gets populated after the service call is finished executing.  However, it seems that the dropdown content is not even visible until the service call finishes.

I have also tried putting a busy indicator outside of the dropdownbutton (on a higher branch of the visual tree).  The problem is that once the dropdownbutton is clicked, it seems that the whole UI freezes until the content gets populated so the busy indicator does not show.

We do not want to make the service call until the user clicks on that dropdown button. Can you please guide me on how I can accomplish this?

Re-using user controls between Silverlight and WPF
I have the Silverlight UI controls (assemblies/dlls) and I am looking to re-use this same user controls in a WPF application. Is this possible? Can I simply add the WPF references in the WPF project and the Silverlight references in the Silverlight project but use the same user controls/code? Or do they each have their own structure/api? Thanks,
