ToolTip for calendar

[Y L]

Hello,

I'm building a RadCalendar with ToolTip to show the time and summary of the events. The example "RadToolTip for RadCalendar " is very helpful, but i'm having a problem that there's always an error "Return Integer.Parse(result.ToString())"--- Input string was not in a correct format. The difference is that I didn't use int for the eventID as the example did, i used uniqueidentifier.

Private Function IsDayRegisteredForTooltip(ByVal [date] As DateTime) As Integer

        Dim connectionString As String = ConfigurationManager.ConnectionStrings("eCalendarConnectionString").ConnectionString
        Dim con As New SqlConnection(connectionString)

        Dim cmd As New SqlCommand("SELECT GUID FROM tblActivities WHERE convert( varchar(10), Start, 101 ) = convert( varchar(10), @Start, 101 )", con)
        cmd.Parameters.Add(New SqlParameter("@Start", [date]))


        Using con
            con.Open()
            Dim result As Object = cmd.ExecuteScalar()

            If result <> Nothing Then
                Return Integer.Parse(result.ToString())

            End If

            Return -1
        End Using
    End Function

When I debugged, the result is always 0.
Can someone help me with this? Thank you very much for your help !
