    Default How to find Checkbox in its event handler?

    Hi Guru?
    The scenario is I am creating a number of checkboxs dynomically and
    when I do that I am also creating event handler for them. So when a
    checkbox is checked, in the event handler I can do something using its
    ID but the problem is how to get its ID?

    --------------- creating checkbox dynamically
    -----------------------------

    Private Function GetUpdateNotificationCheckBox(ByVal valPacketID As
    String) As TableCell

    Dim l_ReturnCell As New TableCell()

    Dim l_CheckBox As New CheckBox()

    l_CheckBox.ID = "chkUpdateNotification" & valPacketID

    l_CheckBox.AutoPostBack = True

    AddHandler l_CheckBox.CheckedChanged, AddressOf
    Me.chkUpdateNotification_Checked


    -------- event handler -------------------------------

    Private sub chkUpdateNotification_checked (byval sender as
    system.object,byval e as system.eventArgs)

    ' I want to get its ID here
    end sub

    Thanks in advance

    um, give it an .ID property when you create it. if it's in a databound
    control, you may have to use it's .UniqueID property.
