Folks, I'll get back to you next week about how to perform entity-level
validation. I'm just digesting the replies from last week and will return to
the problem next week.
In the meantime I've got another binding conundrum, this time about "nested"
binding. The skeleton of my code looks like this:
class MyController
{
public IEnumerable<MyThing> ThingList { ... }
public IEnumerable<MyLookup> LookupList { ... }
}
class MyControl
{
MyController controller = new MyController();
DataContext = controller;
}
<ListBox ItemsSource="{Binding ThingList}">
<DataTemplate>
<TextBlock Text="{Binding Name}" .../>
<ComboBox ItemsSource="{Binding LookupList}" .../>
</DataTemplate>
</ListBox>
Like a schoolbook example, you can see that the ListBox binds to the
ThingList and shows each item correctly. The trouble is the red text which
is a lookup/picker list for each item. I see binding debug error messages
telling me that LookupList is not found, because it's not a property of
MyThing.
I don't know how to tell the ComboBox in each item to bind to LookupList and
not to some property of the bound item. I've tried various tricks in the
binding cheat sheet without luck.
Cheers,
Greg
