you've made some changes in CSS during last versions of Telerik components.
Please, take a look at following style I had in my grid (ca stands for horizontal center alignment)
and now - how it looks in markup:
"GridHeaderGreen ca rgHeader"
"Click here to sort"
- my alignment is ignored!
As you can see, you now add your classes after all user-defined classes. As a result, all user-class css properties, that exist in your classes, too, are overridden - alignment, text weight, etc.! What for do you do this?
How to solve this problem? I have tons of controls with such markup!
