We saw that you have opened another ticket with the same request for Sitefinity 2.5.
Actually, there are two approaches for creating centered sites with Sitefinity:
- You could place the designer control itself in a centered tag for example (div, td, etc).
Using this approach you won't have to change the layouts.
- You could enable the left and right cells of the outer most container of your layout and make the center cell a container. Then you have to set the width only for the center cell (e.g. 800px) and set some spacer control for the left cell and for the right cell (.ascx control which contains a transparent image or " " for example) or you could use r.a.d.editor for this purpose.
(width = 800px)
We hope this information helps.
All the best,
the Telerik team
