    one way to handle this to put add page_error event and use the following code snippet to capture and display the error:

    In my app, I redirected to generic error page and in its page. It works fine ...
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            'Put user code to initialize the page here

            If Not IsPostBack Then
                Dim LastError As Exception
                Dim ErrMessage As String

                LastError = Server.GetLastError()
                If Not LastError Is Nothing Then
                    If TypeOf LastError Is System.Web.HttpException Then
                        LastError = LastError.GetBaseException
                    End If
                    ErrMessage = "Following error occured:" + Environment.NewLine
                    If TypeOf LastError Is System.Net.Sockets.SocketException Then
                        'Remoting Error - Not able to establish connection to Remoting server.
                        'Need to display friendlier message.
                        ErrMessage = "Application Server connectivity error." + Environment.NewLine
                    Else
                        'Standard exception - Could be from DB or anything.
                        ErrMessage = LastError.Message + Environment.NewLine
                    End If

                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "Please try again. If problem persists, please contact product office for support."
                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "<br>"
                    ErrMessage = ErrMessage + "<br>"
                Else
                    ErrMessage = "No Errors"
                End If
                Server.ClearError()
                lblErrorText.Text = ErrMessage
            End If
        End Sub
