My problem with ultrawebgrid Paging
In my Project
In my webgrid  i am showing user two paging style i.e(PagerStyleMode.Numeric in case of record less that 40 )
and PagerStyleMode.quickpages in case of record are greater than 40.
if (pagenumber > 40)
   {
  dgDockets.DisplayLayout.Pager.StyleMode = PagerStyleMode.QuickPages;
   }
  else
   {
   dgDockets.DisplayLayout.Pager.StyleMode = PagerStyleMode.Numeric;

   }
Case: I Need to show minimum 40 pages at once for that i set

 dgDockets.DisplayLayout.Pager.QuickPages = 40;

But in this case it is showing 40 previous page and 40 next page if i click on page no 40 (long pager).

I want that if user click on 40th page all other pages before 40 should hide and next 40 page should show
Like
40 41 42 ----------------------------------
Similarly if he click on 80 all previouse should hide and paging should start from 80

User can also go back to page no 1.

Can someone  help me.
