In earlier versions of the editor, the css class was applied to the image tag itself, which is the correct way to do it. Otherwise the applied css class has no effect on the image.

RadMultiselect control has ClearButton property which should enable displaying the button for clearing all the selected options...

However, eventhough I have this property turned on I don't see any button for clearing the values...  I can only go to the "expected" position for the button and then my mouse cursor is changed and after clicking all the values are cleared as expected... 

"Loading..." text in Combobox with Virtual Scrolling is visible on first set of items loading.
It shows first time "Loading..." text. on scrolling it loads items from PageMethods/WebService but "Loading..." text it not visible i.e. because it is first <LI> item so it is not visible.

Instead of first <LI> item, it  should be at position where it always display while loading more items.

same issue is also in telerik demo website : http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
