Closed: PropertyChanged event doesn't work at client side

Nov 23, 2011 at 9:01 AM

I attempted to customize the generated STE, to detect property changed then invoke some external call to perform validation.

somehow the propertychanged event neved worked.

i guess it's properly due to serialization process. but I explicitly bind the event onDeserialized as well.

maybe this is the nature of WCF data object, only datamembers are usable after serialized?

For auto-generated data members of STE, you can simply subscribe to the property changed event on the client side.

Are you trying to create some client-side only properties? I guess I still do not fully understand what exactly you are trying to do.

i want to detect property changed event.

the generated ste only has this inside

private event PropertyChangedEventHandler _propertyChanged;


I temp addin code into

        public void Initialize()
            this._propertyChanged += new PropertyChangedEventHandler(MySTE_PropertyChanged);

        public MySTE()

        public void OnDeserializedMethod(StreamingContext context)
            IsDeserializing = false;

the generated ste with

but when i made changes over the prop, MySTE_PropertyChanged never get invoked.

nvm, i found out the problem is due to vs2010

whatever changes i made onto the ste, the dll/new-assembly didn't get refresh in another specific project.

i dunno why. I just manually remove the dll in the project output bin/debug , then add back the reference, anything back to normal again.
