    I have a potentially large database whom I'm trying to query for just the items I want displayed on the page I'm looking at. I understand how to use LINQ take and skip to grab the correct range for each page.

    What I am struggling with is setting the RadDataPager.PageCount to a value which would reflect the database's collection size and not the size of the collection in memory. I've tried binding ItemCount to a property that tracks the database collection size similarly to this http://www.telerik.com/forums/itemcount-binding.To my understanding ItemCount in combination with a PageSize binding should create the correct number of pages. I.E. 1 of X.

    The question then is; is it possible to set the PageCount to a value that is separate from the size of the collection that the RadDataPager is bound to?

    Hi,

    Actually, DataPager's PageCount property is readonly and you can not set it. What you can try is to work with pager's ItemCount. I believe that an unbound DataPager will fit in your scenario. Please refer to the Unbound Mode help article which demonstrates how to do the paging outside of the DataPager via LINQ extension methods.
