Symptoms

Telerik RadTabStrip is renders as bullet list (also known as unordered list represented by the UL HTML tag). If for some reason the base CSS file of Telerik RadTabStrip is not loaded your tabstrip would be displayed as a regular unordered list.

The base css file can be found at: RadControls\Tabstrip\Scripts\[version]

Solution

If you are using ASP.NET 2.0 that base style sheet file is served as a web resource. If the web resource handler - webresource.axd - is not properly registered the base css file will not be served to the client. Please try the following:

1. Open the IIS management snap-in (e.g. run inetmgr.exe)
   
2. Right-click your web site and choose properties
   
3. Go to the "Home Directory" tab and click the "Configuration" button
   
    
   
4. A dialog should pop out and you would see the mappings listbox
   
5. Find the entry for the ".axd" extension and edit it by clicking the "Edit" button
   
   
   
6. In the new dialog uncheck the "Verify if file exist" check box if it is checked.
   
    
7.
