Thanks to Tim for this solution. In order to add the CSS Friendly adapter to your project, you will need to:
- Download CSSFriendly.dll and CSSFriendlyAdapters.browser from here.
- Inside your project, add a reference to CSSFriendly.dll.
- Add the special folder App_Browsers to your project, and copy the file CSSFriendlyAdapters.browser.
The CSS Friendly Control Adapters will render all the listed controls (Menu, TreeView, DetailsView, …) using CSS and HTML standards.
