Great job ……

how can use this code ASP.net Ajax enabled paging , should convert the querystring process to postback ?

code sample please

thanks in advance

Partial Class _Default
Inherits System.Web.UI.Page

Private Const NEXT_PREVIOUS_CLASS As String = “nextprev”
Private Const CURRENT_CLASS As String = “current”
Private Const PREVIOUS_TEXT As String = “« Previous”
Private Const NEXT_TEXT As String = “Next »”

Dim AllowMultiColumnSorting As Boolean = True

Dim sortExpression As String

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Me.CurrentPage > 0 Then
Me.Gridview1.PageIndex = Me.CurrentPage – 1
Else
Me.Gridview1.PageIndex = 0
End If

End Sub

#Region “Paging Procedures”

Private ReadOnly Property CurrentPage() As Integer
Get
Dim thispage As Integer
If Not IsNothing(thispage) Then
thispage = Convert.ToInt32(Request.QueryString(”Page”))
If thispage = 0 Then
thispage += 1
End If
End If

Return thispage
End Get
End Property

Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As EventArgs)
Dim container As Panel = DirectCast(Gridview1.BottomPagerRow.FindControl(”pagingContainer”), Panel)
container.Controls.Add(GetPreviousControl())
Me.AddMainPaging(container)
container.Controls.Add(GetNextControl())
End Sub

Private Sub AddMainPaging(ByVal container As Panel)
‘ the number of pages to display
‘ around the currently selected page
Dim adjacents As Integer = 3

‘ don’t need to break it up
If Gridview1.PageCount Me.CurrentPage AndAlso Me.CurrentPage > (adjacents * 2) Then
‘ hide on both sides
Me.AddFirstTwo(container)
Me.AddRange(Me.CurrentPage – adjacents, Me.CurrentPage + adjacents, container)
Me.AddLastTwo(container)
Else
‘ hide just the beginning
Me.AddFirstTwo(container)
Me.AddRange(Gridview1.PageCount – (2 + (adjacents * 2)), Gridview1.PageCount, container)
End If
End If
End Sub

Private Sub AddDots(ByVal container As Panel)
Dim dots As New Label()
dots.Text = “….”
container.Controls.Add(dots)
End Sub

Private Sub AddFirstTwo(ByVal container As Panel)
Me.AddRange(1, 2, container)
Me.AddDots(container)
End Sub

Private Sub AddLastTwo(ByVal container As Panel)
Me.AddDots(container)
Me.AddRange(Me.Gridview1.PageCount – 1, Me.Gridview1.PageCount, container)
End Sub

Private Sub AddRange(ByVal startIndex As Integer, ByVal endIndex As Integer, ByVal container As Panel)
For i As Integer = startIndex To endIndex
container.Controls.Add(Me.GetMainControl(i))
Next
End Sub

Private Function GetMainControl(ByVal currentIndex As Integer) As Control
If Gridview1.PageIndex + 1 = currentIndex Then
Return GetLabel(currentIndex.ToString(), CURRENT_CLASS)
Else
Return GetHyperLink(currentIndex.ToString(), Nothing, String.Format(”~/Default.aspx?Page={0}”, currentIndex))
End If
End Function

Private Function GetPreviousControl() As Control
If Me.Gridview1.PageIndex

Thanks for the work.
