I've just upgraded to the latest release and am very disappointed to discover that the custom skin for my RadCalendar no longer works because all the styles have been renamed in the latest release.

I cannot understand why this was done, nor why there was no information to indicate that it had been.

I had previously spent considerable time customizing this skin, and after upgrading spent some more time trying to work out why my skin wasn't working. Now, I have to spend even more time re-customizing the skin.

If you are using a custom skin on a RadCalendar and haven't upgraded to v 2008.3 yet, please be aware of this issue.

Hello John,

We have announced about the change in a blog post almost a month ago:

http://blogs.telerik.com/DimoDimov/Posts/08-10-14/Optimized_Rendering_and_Skins_for_RadCalendar_for_ASP_NET_AJAX.aspx

and in our release notes last week:

http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q3-2008-version-number-2008-3-1105.aspx


Actually, migrating your custom skin to the latest version of RadCalendar is easy, you just need to modify the selectors following these guidelines (you can also refer to one of our skins located in the Skins subfolder of your RadControls installation to see how the selectors are organized)

Let us know if you need more information.

Hi Dimo

Thanks for your reply.

I did actually read the release notes, however I didn't interpret "All skins are reworked for the new rendering" as "all css classes have been renamed and your custom skin will break". I considered that 'skins' referred to the embedded skins which we are not using and therefore should not have had any impact on us.

With regards to the blogs - there are a significant number of posts there and I simply don't have time to regularly check for new ones that may or may not be relevant to our development.

I appreciate the guidelines you've posted, they should make it easier for us to fix our skin.
