Pass wpf dependency property to usercontrol for child control

I have a custom MyControl: UserControl with a dependency property

string Text

Inside MyControl in XAML I have a TextBox.

I want to bind the Text dependency property of MyControl to the text dependency property of the TextBox .

What's the best way to do this? Can I declare the MyControl dependency property to go to the child dependency property?

The easiest way is to assign an attribute x:Name="root"

to the root of your file MyControl.xaml

, then use an anchor like this for yours TextBox

:

<TextBox Text="{Binding Text, ElementName=root}" />


(You can provide your name for root

.)

My answer here details a good example of how you can do this. Essentially, your controls are bound to properties in viewmodels, and the child view model has a dependency property that allows you to bind the child control and can output a value to the child view model. The example is in Silverlight, but the implementation is the same for WPF.
