I generally declare my dependency property as normal, then bind to it from the
UserControl itself. So let’s say you had a real DP called TitleText, I’d do
something like:
<UserControl ... x:Name=”me”>
<TextBlock Text=”{Binding TitleText,ElementName=me}” />
... so now the owner of the UserControl can set TitleText and it will be
reflected by the child control.

Subject: Child controls as dependency properties
I have a UserControl which contains children labels, buttons and text boxes. I
need to expose the properties of the child controls as dependency properties of
the parent. Like this naive and incorrect code:
public string TitleText // I want this to be a dependency property
{
get { return childLabel.Text; }
set { chidlLabel.Text = value; }
}
I’ve searched and searched, but can’t find a single example of there anyone
does this. They talk about it, but no one supplies any example. I’ve fiddled
with code but I can’t figure out how to alter the standard DP coding pattern to
override the getter and setter. Does anyone know the trick?
