Bug while public/private modification of property

[ttodua]

you can reproduce the error too.
just use this code (indicator):

however, when I attach that to chart,i get this error:


but if i change the property "EnabledRegions" from public to private, then it starts working...
what is the problem? maybe it's but in NT.

Hello TazoTodua,

Thanks for opening the thread.

I could not hit the error with the example provided, but I can explain the error you are inquiring on.

Public properties will be serialized so they can be retrieved at a later point. For example, from a workspace or chart template. Brushes need to be serialized because the Brush itself can't be directly written to XML. This same concept applies to types that cannot be serialized.

These public properties could be made private, or they could be include a serializable type like a string that the the property can be converted too. Alternately, the XmlIgnoreAttribute could be used to prevent the public property from serializing all together.

Please let me know if I may be of further assistance.

thanks as always for excellent answer.

but one thing we wish....
i dont know, it is easy for NT developers, to detect if "public" type (or anything variable) that is going to be cached/serialized (like brushes or etc), why the compiler (or NT) does the serialization job itself?
it would have been useful for us (developers) to code things easily, without taking care which types need serialization and which not...

we could just set:

public xyz the_name ....


and NT should take care whether "xyz" is an object or not...
It would be good if you send this request to Devs.
