Protected Sub chkLocationArrival_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim chk As CheckBox = DirectCast(sender, CheckBox)
Dim item As GridDataItem = DirectCast(chk.NamingContainer, GridDataItem)
Dim DestinationLocationEvent_ID As Int32 = CInt(item("Call2LocationEvent_ID").Text)
Dim CurrentLocationEvent_ID As Int32 = CInt(item("CurrentLocationEvent_ID").Text)
The problem is that the items Call2LocationEvent_ID & CurrentLocationEvent_ID have visible=false in the grid, and on postback only return a   not any value.
Has anyone else found this?
