LINQ and pagination [duplicate]

Question

We need to fetch data from a database using LINQ. We now need to implement pagination.

I suppose at a time we need to fetch 10 records at a time and when we click the Next button then it will fetch the next 10 records from db.

Please guide me with code. thanks

Answer 1

I always use the following code:

public static class PagingExtensions {     //used by LINQ to SQL     public static IQueryable<TSource> Page<TSource>(this IQueryable<TSource> source, int page, int pageSize)     {         return source.Skip((page - 1) * pageSize).Take(pageSize);     }      //used by LINQ     public static IEnumerable<TSource> Page<TSource>(this IEnumerable<TSource> source, int page, int pageSize)     {         return source.Skip((page - 1) * pageSize).Take(pageSize);     }  } 

That is a static class, which you can include in your sources. After adding this class you can do the following:

MyQuery.Page(pageNumber, pageSize) 

Answer 2

The LINQ Take() function will limit how many items are taken. The Skip() function will ignore the first n items. Something like this might work:

myDataSource.Skip(pageSize * curPage).Take(pageSize)
