My brain just can't cope!

So I have a repeater which binds page numbers. That's all fine.

I need to know how to make the paging so that they are in "chunks" of a max of 10 page numbers being displayed at a time.
Then if they select a page number, it will show the previous x pages and the next y pages (within the 10 chunk range).

similar to google paging I guess.

Not using pagedDataSource/gridview/gridlist please! This is just purely getting the page numbers.

So yes, if it helps - it is pretty much the same/similar to google paging behavior.
