  Hi,

  I appriciate your solution.

  How can i implement the same functionality in ASP.net 2.0?

  I am creating the controls dynamically through code behind and adding evend handler but it is not working.

  for e.g

  For iCounter As Integer = 0 To sAnswers.Length - 2
                          Dim cb As New CheckBox
                          tblCell = New TableCell
                          tblRow = New TableRow
                          cb.ID = "CheckBox" & (iCounter + 1).ToString
                          cb.Text = sAnswers(iCounter).ToString '& "<br/>"
                          AddHandler cb.CheckedChanged, AddressOf MyCheckBoxCheckedChangedEvent
                          tblCell.Controls.Add(cb)
                          tblRow.Controls.Add(tblCell)
                          tblQuestion.Controls.Add(tblRow)
  Next

  Private Sub MyCheckBoxCheckedChangedEvent(ByVal sender As System.Object, ByVal e As System.EventArgs)
   If TypeOf (sender) Is CheckBox Then _
       MessageBox.Show("Cuaght Checked Changed of " & DirectCast(sender, CheckBox).Name & " In " & DirectCast(sender, CheckBox).Parent.Name)
  End Sub

  Thanks and Regards,
  Rahul

  Hi

  maybe you have to set the checkbox autopostback value to true

  cb.AutoPostBack = true
