Question

var skip = selectedPage*pageSize;
            var take = Math.Min(result.DataSourceCount - skip, pageSize);

            List<SENTINEL_OPERATION> results = sentinelOperationManager.SearchSentinelOperations(sid).Skip(skip).Take(take).ToList();

My last page always gets empty. Im using a PageDataSource to get the pagesize and sending the clicked page using jquery ajax get. Did i miss something? Thanks

I bet, that selectedPage starts from 1 in your code and this is causing erros. Then you get skip == pageSize when on first page, and you go “out of range” on last page, but you are skipping the “real” first page.

If selectedPage starts from 1, then change this formula to:

var skip = (selectedPage - 1 ) * pageSize;

Also – there is no need to manually calculate take value. You can just pass pageSize and it will always work. If your data source will not contain enough elements, nothing wrong will happen, just elements that are available will be returned.
