How can I use the same paging control which is available in blogpost in dashboard?
Do you mean the next/previous the Blog Summary uses when it has more blog items than you set in the "number to show"? Do you also mean the dashboard as in the dashboard module in the admin when you login?
If so, in just recently looking at the dashboard module myself, its not setup anything like you describe. It's a bunch of DIV sections with CSS. The best way might be some jquery as what you are talking about I believe is fairly big undertaking.
How many items do you have on your dashboard?
