Migrating Skins from RadPanelBar ASP.NET to ASP.NET AJAX

Updated on Aug 24, 2026

Since RadPanelBar for ASP.NET AJAX inherits its rendering from RadPanelBar for ASP.NET "Classic", it is rather easy to migrate a skin.

There are only two changes that are needed in the skins:

1. add the control-specific prefix ("rp" to the CSS class names and capitalize the first letter of the "Classic" class names afterwards

2. change RadPanelbar_SkinName to RadPanelBar_SkinName

The following table lists all class names in the "Classic" version of RadPanelBar and their equivalents in the RadPanelBar for ASP.NET AJAX:

RadPanelBar "Classic" class name	RadPanelBar for ASP.NET AJAX class name
RadPanelbar_Skin	RadPanelBar_Skin
link	rpLink
focused	rpFocused
expanded	rpExpanded
expandable	rpExpandable
text	rpText
rootGroup	rpRootGroup
group	rpGroup
item	rpItem
first	rpFirst
last	rpLast
disabled	rpDisabled
separator	rpSeparator
level1	rpLevel1
slide	rpSlide
