Hi,
I have this function that returns a DataTable :
Public Shared Function GetDataTable(ByVal PageSize As Integer, ByVal CurrentPagea As Integer) As DataTable
Dim dtData As New DataTable
dtData = da_Book_Content.GetDataContent()
'TODO : how to do data paging for dtData with Linq
Return dtData
End Function
On a page, I have DataList to display the data. It works but I want to implement the paging feature. How do I do that with so I be able to use Linq lazy loading feature ?
Thanks.

if the DataTable is already coming from somewhere else not LINQ2SQL, then Lazy Loading doesn't come into play.
However you can use LINQ2DataSets to take advantage of the Skip() and Take() extension methods.
You need to add a reference to the assembly:
System.Data.DataSetExtensions.dllthen you can write your function like this:Public Shared Function GetDataTable(ByVal PageSize As Integer, ByVal CurrentPagea As Integer) As DataTable Dim dtData As New DataTable = da_Book_Content.GetDataContent() Dim query = dtData.AsEnumerable().Skip(CurrentPage).Take(PageSize) Return query.CopyToDataTable() End FunctionAngkor Wat : I used this .Skip((CurrentPage - 1) * PageSize).Take(PageSize).CopyToDataTable Thank a lot.
