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...
similar to these: http://willowsystems.github.io/jSignature/#/demo/ http://www.supersignature.com/ Sure you could do something really cool like a sketchpad, with a background image.
"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
