[VS 2008] Datarepeater checkbox repeats every 10 rows

I'm writing an application in VB.net using the Visual Basic Power Packs DataRepeater. I have a loop that runs on the rows with a checkbox checked in them. When I run the loop it checks every 10th row from the ones I've selected. There is no other event linked to the DataRepeater or the controls inside. Just a button at the bottom. The checkbox is not bound to anything. Any reason why the DataRepeater would do this?  The checkbox is not bound to a database field.

I read this checkboxstate with the following code:

  For i As Integer = 0 To dr.ItemCount - 1
                Me.dr.CurrentItemIndex = i                
                Dim item As DataRepeaterItem = Me.dr.CurrentItem

                Dim chk As New CheckBox
                chk = item.Controls("chk1")               

                If chk.CheckState = CheckState.Checked Then
                    MsgBox("CHECKED!!|)                   
                End If

            Next

I would recommend to display states for all DR rows incl. the i and chk.CheckState value in Debug window.

BTW, the Dim  chk As New CheckBox  is not necessary and you could use just

Dim  chk As CheckBox = item.Controls("chk1")

Solution (doesn't need to set the currentindex):


 For Each rowItem As DataRepeaterItem In dr.Controls
                
                Dim chk As New CheckBox

                chk = rowItem.Controls("chkApply")

                If chk.CheckState = CheckState.Checked Then

                    If rowItem.ItemIndex <> -1 Then
                        j += 1
                    End If

                End If
         next
