How can I bind certain properties belonging to a custom control?

Question

If I have the following control:

public partial class MyControl : UserControl{
    public string MyControlText{
        get { return MyTextBox.Text; } 
        set { MyTextBox.Text = value; }
    }

    public MyControl(){ ... }
}

How can I bind to the "MyControlText" property when I place the control on one of my pages, like so:

<local:MyControl MyControlText={Binding Path=SomeField} />

Thanks!

You need to make the property a dependency property. The documentation for the DependencyProperty class shows you how to do this:
