To make customizing the appearance of RadNotification as easy as possible, the control uses skins. A skin is a set of images and a CSS stylesheet that are applied to the HTML elements which make up the notification, defining the look and feel.
To apply a skin, set the Skin property of the RadNotification. You can set the it by using the properties pane, the server-side property or the control's Smart Tag.
RadNotification is installed with a number of predefined skins:
The Material skin is available for the Lightweight RenderMode only. If you experience visual issues with it, make sure your controls are not using the default Classic mode.
The Shadow and Rounded Corners are achieved via CSS3 properties and will not have effect under browsers that do not support them (such as IE8 and prior, FireFox 3, etc).
