Forms Data Controls :: How To Get A GridViews Paging Text Like "item 20 - 30 From 54 Items" With A LinqDataSource

before I started working with LinQ I used Objectdatasources to bind a GridView.

To get a label like "item 20 - 30 from 54 items" I used a dataview like this:

Dim dv
As Data.DataView = ObjectDataSource.Select()
Dim count
As
Integer = dv.Count()
Dim first
As
Integer = 1 + (Grid_View.PageSize * Grid_View.PageIndex)
Dim last
As
Integer = first + Grid_View.PageSize - 1
If last > count
Then
last = count
End
If

How can I do this if I bind my GridView with a LinqDataSource?
