Indeed, currently there is no option for setting a skin for all RadToolTipManagers on the page via the RadSkinManager. I have brought this to the attention of our developers, nevertheless I am not able to provide a firm estimate when it will be implemented. You can follow the status of this feature via its PITS Item
For the time being you can set the Skin
property of RadSkinManager in order to apply a global skin if all controls in your project are using the same skin. In case the skin of the tooltips has to be different, you will need to configure the Skin
property of every RadToolTipManager or create an ASP.NET Theme
that will define a configuration of the tooltip managers and apply it to your pages.
