Whats the deal with going back to the <asp:DropDownList ID="SitesLst" runat="server" MaxHeight="300px" /> in all administration. Another thing to keep us from styling to anything but square corners and white button. dnn called other controls which cannot be styled.
The css for the jquary ui is not consistent with normal jquary styles, pain to restyle, why not the normal styles, border-radius:0 why a 0 statement, backround:none = redundant.
Pay Attention to the ability of re-styling the jquary ui with ease or at least comment on your unneeded changes. If you are going to used the jquary ui figure out theme roller and stick with its styles so its a copy and paste situation to change ui styles.
Lots of redundant and unused styles in all stylesheets. Have you thought about IE 9.0, alot of your moz-linear-gradient or gradients with border-radius does not work in ie 9.0 that whats up with the square corners on tabs and that ugly window. Or just call the jquary css like @import url("css/jquery-ui-1.8.12.custom.css"); which is not CSS3 friendly but at least we could easily change all jquary ui styles easily. Give the window some effects as move and re-size and re size to content, which is easy with the Telerik Window.
With the asp controls and styling we are going back in time. Intentions destruction or the last two years of progression. Control Panel now fully sucks, ribbon bar destroyed. Admin backend with standard asp:dropdowns, yellow background?????????? damit.
