Hi,
you need to ensure that your binding is working correctly - for that, look at the output window - is there a
BindingExpression Error that you might need to fix?
If thats not the case, review your binding in the UI control eg. ListBox should look something like this:
<ListBox ItemsSource="{Binding WCFItemsList}"/>
where WCFItemsList should be your implementation of the observable Collection in the bound ViewModel:
public property ObservableCollection<MyWCFItems> WCFItemsList
{
get
{
return _WCFItemsList;
}
}
Beyond from this, you should also test with debugger breakpoints in the viewmodel to ensure that your observable collection is loaded correctly.
You might not see the count in the UI because its not an INotifyPropertyChanged property?
Its realy hard to say anything specific since you give no useful source code sample but I hope these checkpoints help you investigate the issue ...
