Problem with WPF Components

Hi,

I have followed the link posted in the forum question here: Previous Telerik Forum Question about installing Telerik objects into VS2008 toolbox to install the WPF components into the VS2008 toolbox however it seems something unusual has happened with a few components.

When I place (for example) a RadRibbonBar onto my form it only shows a bounding box, once deselected from its initial placement you cannot click it to focus it again, furthermore if you run the application it only seems to show 'parts', the same occurs with RadTreeView and RadMenu.

With objects like RadMenu and RadTreeView if i choose to edit the items in the properties tool window of VS it opens the maintain items dialog but the ability to add new items is greyed out.

I have uninstalled, reinstalled and restarted inbetween both VS and Telerik WPF components so many times trying to rectify this problem, I am using Telerik components I downloaded from the members area today, so they are definately the latest version. VS is updated to the latest version.

Please help, I can't program WPF apps with Telerik at the moment!

Thanks

Xavier.

Get coordinates of a given RadTreeViewItem

Hi, I'm trying to figure out how to do this. Is there a method or a property that returns the X and Y coordinates of an item?

Thanks!

EDIT:

I need the coordinates relative to the parent of the RadTreeView and relative to the RadTreeView itself.

Thanks.

How can I find the document in DocumentHost programmatically ?

The RadDocking control has properties and methods for working with Tabbed Documents quickly ?
Close/Open etc... Document programmatically.
I would like to perform a LINQ query (or for/foreach) to find the document that implements a particular interface, this is possible?

Example :

    
            private IDebugEditor GetDebugEditor() {  
        
                var res = from w in radDocking.Documents where w is IDebugEditor select w;  
        
                if (res.Count() != 0)  
        
                    return (IDebugEditor)res.First();  
        
                return null;  
        
            }
