first of all: THANK YOU FOR YOUR HELP :)

yes, my wcf call returns an address with the property address1, address2 etc.

i bind to the propertys of the viewmodel. i set the datacontext of my view with:

usercontrol.datacontext>
addressviewmodel/>
/usercontrol.datacontext>


when i call synchronus, then it works. i dont even have to call the raisepropertychange in the setter of the Address as discussed above.

And exactly this is the confusing point. I thought the UI will update (adress1, address2, etc) when i raisepropertychanged on the whole Address but it wont...

All servicefunctions/sql-statements etc. i use are "autogenerated" from a datacontract on the serverside. and the class Address has address1, address2, address3 to hold street and additional stuff... i know that this is not looking good^^
RaisePropertyChange(()=>address1) also works. The strange thing for me is, that the set of the propertys isn't called, when i update the whole object. with your info on your solution, i will call the raiseprop for all properties in the setter of the object:

#region Properties
public Address Address
{
get
{
return _address;
}
set
{
if(Address != value)
{
_address = value;
if(address1 != value.address1)
RaisePropertyChanged(() => address1);
if(address2 != value.address2)
RaisePropertyChanged(() => address2);
...
}
}
}
so i dont have it in method. do you think this is a good solution?

Hi db7uk,
i will have a look at the NotifyPropertyWeaver. For the second part of your solution:

that is the part i do not understand. i raise the propertychangedevent in the setter of the property. please look at my edit on the question. maybe there is an other problem... ???

Okay... as more as i read about mvvm as better it looks to me. my project will be wrapped in this pattern an then i will use the way you described. thank you!

And the declarative way is only possible over the mvvm pattern?

I'm reading this great article at the moment http://www.codeproject.com/Articles/100175/Model-View-ViewModel-MVVM-Explained and i think i will use this pattern.
But do you know, that there is no other way to bind via xaml for me? (so i can mark this question as answered...)

thank you for your help. PS: you can have a clean design without patterns like these ;)

this referes also to the mvvm model. might be that i have to change a lot... :(

Hi Oleksandr, thank you for this answer. I tried to fiddle your code into mine but i do not have the "RaisePropertyChanged" event.
And because of time, i am not able to learn the mvvm model at the moment... and i cant use the binding in the code, because i need to autogenerate a lot of the xaml-pages.

Yes. The mesage i always get when i try to delete the constraint is:

> ALTER TABLE [Customer]
DROP CONSTRAINT orderAddress_fk
The foreign key constraint does not exist. [ orderAddress_fk ]

But in the UI its still shown and i still can delete it via ui...???

Hey Zoltán. It might be a litlle more confusing than yout thought. I can delete the foreign key via the UI. There must be something wrong with my delete query... again: thanks for your help!!!

okay there is. thank you for your reply. but my problem still exists. i have to delete the foreign key via query...

I am using SQLSM Express 2008 and there is no option in the propertys window, allowing to define any constrains exapt of the primary key. But i know that the pk exists. there is an FS mark in the UI description of the columns and i cant delete it.
