Hi

I'm trying to create a schedule with my own custom schedule item class.  I started with the tutorial 4 and it seems to work.  But when I go to setting up saving the schedule (ie serialization) as demonstrated in tutorial #9 the saveto/loadfrom overrides don't get invoked.  However, the schedules do get saved and loaded except the "kept" property gets lost?  When I edit a schedule item after its been loaded back in, the "kept" part of it is lost.  When I add a new item its there, but once I save or load its gone!

I don't know what I'm doing wrong.

Here's the saveto/loadfrom code:

Public Overrides Sub SaveTo(ByVal writer As System.IO.BinaryWriter, ByVal context As SerializationContext)

       MyBase.SaveTo(writer, context)

       writer.Write(Kept)
    End Sub

    Public Overrides Sub LoadFrom(ByVal reader As System.IO.BinaryReader, ByVal context As SerializationContext)

       MyBase.LoadFrom(reader, context)

       Kept = reader.ReadBoolean()
    End Sub


Here's the code for the form load event where I register my schedule class.

       Calendar.InteractiveItemType = GetType(MyScheduleClass)

       Schedule.RegisterItemClass(GetType(MyScheduleClass), "MyScheduleClass", 1)


Thanks

Hi Meppy

Thanks for the quick response.  I pasted in the saveto/loadfrom with the system.xml...... and put breakpoints on each.  When I run it and save it, they don't get invoked either. 

I'm using the following code to save a schedule

         

Don't those methods get called when you use SaveToDataSource()?

Thanks for your help.

These methods are only invoked when you are serializing to a XML file, i.e. when you call Schedule.SaveTo and pass ContentType.Xml as the second argument. Anyway, I am afraid custom item serialization is not yet supported when you save and load the schedule to and from a database.

I don't think it is currently possible to perform custom item serialization during saving in a database. I will check with our developers whether this feature can be implemented easily and let you know.
