Hey,
I'm using web refernce call in new working thread in my application as follow:

Thread callRunner = new Thread(delegate() 
    { _mediator.IncomingCallDetails(phoneNumber); }); 
callRunner.Start() ;   

the _mediator calls the web refernce and replay to the caller in event as follow:

void IncomingCallComplited(IncomingCallEventArg args)  
{  
    Caller = args.Caller;  
    Lodgers = args.Lodgers;  
    PreviousMissions = args.PreviousMissions;  
}  

Caller ,Lodgers and PreviousMissions are properties of an object that bind to GUI element,as for now the binding works fine and I can see the values from the web reference in screen my question is should I use Dispatcher in the event or in any other phase ? and if I do can someone please explain why? Thanks
Eran
