Here's additional information regarding your question how to assign images to the tab items in r.a.d.dock. You can try and use the following method to do so until we implement this feature in the next release.
void SetIcon(Bitmap img, DockPanel panel) { DockPresenterControl presenterControl = panel.DefaultPresenter as DockPresenterControl; RadTabStripElement tabStripElement = (presenterControl.DockPresenterElement.Children[2].Children[2] as RadTabStripElement); foreach (DockableTab tab in tabStripElement.Items) { if (tab.Element == panel) { tab.Image = img; return; } } }
where Bitmap img is the image you would like to set and DockPanel panel is a reference to the docked IDockable instance.
