I have two css classes like this:

.folderTextON,a.folderTextON:active,a.folderTextON:link,a.folderTextON:visited {color:#fff;font:bold 10px/12px Verdana,Arial;text-decoration: none;}
a.folderTextON:hover         { text-decoration: none; color: #FFFFFF; }

.folderTextOFF,a.folderTextOFF:active,a.folderTextOFF:link,a.folderTextOFF:visited {color:#AD9596;font:bold 10px/12px Verdana,Arial;text-decoration: none;}
a.folderTextOFF:hover         { text-decoration: none; color: #fff; }

I also have LinkButton like this:

<asp:linkbutton id=”linkbtn” CssClass=”folderTextOFF” Runat=”server”>A Link Button</asp:linkbutton>

On code behind I tried to set the css class like this:

linkbtn.CssClass=”folderTextOn“;

This does not not work. On any browser at all. The class code and all others are ok.Whats the problem?

Problem is the CssClass I assigned did not have ON all uppercase as I defined on the style. Modifying that this works:

linkbtn.CssClass=”folderTextON“;

Apparently on code behind class name need to be case sensitive. Whereas it does not matter on the asp page.
