This example shows how RadFormDecorator can be used along with Telerik controls such as RadTabStrip, RadTreeList, RadToolTip, RadGrid. RadFormDecorator will style any standard elements like CheckBox, Textarea, Fieldset, Input, Label, H4, etc. in these controls' templates and will apply visual effects like mouse over and rounded corners thus providing better visual experience.
In addition to the predefined skins, you can easily create your custom ones by following the instructions in the documentation. More information on how skins work and how to create custom ones is available in section Telerik UI for ASP.NET AJAX Fundamentals / Controlling Visual Appearance (online version).
NOTE: In order to have the RadToolTip and the RadFormDecorator work correctly in integration you should declare the RadFormDecorator before the RadToolTip on the page.
