This might help you I recommend you look into using MVVM for your situation (which is a common one in WPF).
What you will end up doing is create a single ViewModel (VM) which will contain your business data (think of it as temporary table). Then you will bind your controls specific data needs directly to properties on the VM.

will help you I am having trouble getting the following scenario to work (this code is not the actual code but the principals are the same. Basically I need to pass a value down from a MainPage down to a nested "reusable user control" that binds to it's own properties. I want to see the "This is it!" text on the screen but it's not being set in the SilverlightControl2 control (I suspect due to the setting of the DataContext) - but I how do I fix it? , As soon as you find yourself feeling the need to do this:-
code :
this.DataContext = this; 
    <Local:SilverlightControl2 x:Name="MyControl2" />         
public SilverlightControl1()  
    MyControl2.SetBinding(SilverlightControl2.TwoValueProperty , new Binding("OneValue") { Source = this });

<Grid x:Name="LayoutRoot" Background="White">               
    <TextBlock x:Name="MyTextBox"  Foreground="Blue" />               
public SilverlightControl2()  
    MyTextBox.SetBinding(TextBox.TextProperty , new Binding("TwoValue") { Source = this });  
<TextBox Text="{TemplateBinding TwoValue}" />

wish helps you Probably the easiest is to use Ancestor Binding to find the DataContext you want.
For example:
code :
<TextBox Text="{Binding DataContext.SomeProperty, 
    RelativeSource={RelativeSource AncestorType=myParentControlType}}" />
<TextBox Text="{Binding DataContext.SomeProperty, ElementName=myParentCtrl}" />

To fix the issue you can do I'm trying to work out how to Data Bind a list of UserControls to a WrapPanel but I'm not having much luck searching around. , Try something like this:
code :
<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled" ItemsSource="{Binding YourSource}">
            <WrapPanel IsItemsHost="True" />
<ItemsControl ItemsControlScrollViewer.HorizontalScrollBarVisibility="Disabled" ItemsSource="{Binding YourSource}">
                   <WrapPanel IsItemsHost="True" />

Any of those help I would like to bind property from the main window's DataContext, above you can see my UserControls and models. So I want to bind the Model.ID.Label1 and Model.ID.Label2 properties to the main_id/card_1/top and main_id/card_1/bottom controls. I hope it's clear. If I enable the ref_lbl Label it will shows the "lbl1", the card_2 still working with the hardcoded texts but the card_1 will be blank. What should I modify to fix the binding on card_1? , Remove
code :
DataContext="{Binding RelativeSource={RelativeSource Self}}"
<Controls:Card ... TopLabel="{Binding Label1}" />
<Label ... Content="{Binding TopLabel,
    RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=UserControl}}" />
