RadTreeView for ASP.NET AJAX

RadControls for ASP.NET AJAX
  • Drag and drop does not work between IFrames (or Frames). There is no workaround. As a result, if you use RadPane (in RadSplitter) and set its ContentUrl property it will render an IFrame and you will not be able to drag and drop nodes on that pane. You can find a workaround in this forum post.
