Resolving External User Control x:Name Convention Bindings in Caliburn.Micro
I'd like to use x:Name binding to resolve property bindings in nested, satellite user controls via Caliburn.Micro's conventions.
The UI for our Views is pretty standard. We have a satellite project that contains user controls which are then used to compose the UI in our Views, similar to the example below:
<UserControl x:Class="Company.CompanyView" ...>
<StackPanel>
<customControls:CompanyNameControl />
<customControls:CompanyAddressControl />
....
</StackPanel>
</UserControl>
The ViewModel for this View exposes properties that will be bound to by the components that make up these user controls.

{
public string CompanyName { get; set; }
public string CompanyAddressNo { get; set; }
public string CompanyAddressStreet { get; set; }
...
}
The user controls are typically simple, but they are heavily reused in many different views. Here's an example of what one may look like:
<UserControl x:Class="CustomControls.CompanyNameControl ...>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Company Name: " />
<TextBox x:Name="CompanyName" /> <!--This is how I'd like to bind-->
<TextBox Text="{Binding CompanyName}" /> <!--This is how I currently bind-->
</StackPanel>
</UserControl>
My understanding is that in Caliburn.Micro, x:Name convention-style binding only works if there is a ViewModel for the View. In this case, the UserControl is not, itself, a View. It's used to compose the View.
Is there a way to make the binding resolve to the ViewModel for the View upon which the nested, satellite UserControl is composed?
You need to use cal:Bind.Model="{Binding}" where you use the control; cal is an xmlns for Caliburn.Micro.
<UserControl x:Class="Company.CompanyView" ...>
<StackPanel>
<customControls:CompanyNameControl cal:Bind.Model="{Binding}"/>
<customControls:CompanyAddressControl cal:Bind.Model="{Binding}"/>
....
</StackPanel>
</UserControl>
