How do I reference a dynamically added CheckBox control?

I've added a CheckBox control during RowDataBound of the gridView control.  Like:

Dim chk As New CheckBox
cell = e.Row.Cells(0)
chk.ID = "IsSelected"

How do I reference the value of that CheckBox outside of the RowDataBound event?

You can do it something like this,

            Dim cb As CheckBox
            For Each item As GridViewRow In GridView1.Rows
                cb = CType(item.Cells(0).FindControl("chkSelect"), CheckBox)
                If cb.Checked = True Then
                    ''Do Something
                End If

Or, in your case, something like this,

            Dim chk As CheckBox
            For Each item As GridViewRow In GridView1.Rows
                chk = CType(item.Cells(0).FindControl("chkSelect"), CheckBox)
                Dim ID as String = chk.ID
