[RESOLVED] Paging with a datarepeater

[scuzymoto]

Adding a paging feature to data displayed in a data repeater is decidedly easy with the simple addition of a paged data source.

I couldn't find much information on this topic in this forum but I did find some decent C# code elsewhere that I translated to VB.Net. Since this forum has helped me more times than I can count I always like to post my solutions in case they some day help someone else.

Use this code in your page load and make sure you have a label called lblCurrentPage above your repeater and two hyperlinks called lnkPrev and lnkNext below your reader. You will also need a data adapter (mine is called sdaData here).

This code handles the rest.

If Not Me.Page.IsPostBack Then
            Dim cn As New SqlClient.SqlConnection(Session("PropertyConnection"))
            Dim cm As New SqlClient.SqlCommand("", cn)
            Dim ds1 As New DataSet
            Dim strPsn As String
 
 
            sdaData.SelectCommand.Connection = cn
            sdaData.SelectCommand.CommandText = "select * from [orders] where customer = '" & strWhatever & "' order by orderdate desc"
            sdaData.Fill(ds1)
 
            Dim objPds As New PagedDataSource
            objPds.DataSource = ds1.Tables(0).DefaultView
            objPds.AllowPaging = True
            objPds.PageSize = 5  'sets number of pages to display
            Dim CurPage As Integer
            If Len(Request("Page")) > 0 Then
                CurPage = CInt(Request("Page"))
            Else
                CurPage = 1
            End If
            objPds.CurrentPageIndex = CurPage - 1
            lblCurrentPage.Text = "Page: " & CurPage.ToString() & " of " & objPds.PageCount.ToString()
 
            If Not (objPds.IsFirstPage) Then
                lnkPrev.NavigateUrl = "mypage.aspx?page=" & CStr(CurPage - 1)
            End If
            If Not objPds.IsLastPage Then
                lnkNext.NavigateUrl = "mypage.aspx?page=" & CStr(CurPage + 1)
            End If
 
            Repeater1.DataSource = objPds
            Repeater1.DataBind()
        End If

It should be very simple to do the same for a datalist.
