How do I Access Buttons inside a UserControl from xaml?

Question

At work I have several pages, each with buttons in the same places, and with the same properties. Each page also has minor differences. To that end, we created a userControl

Answer 1

rather than use many dependency properties, prefer style approach. Style contains every property available for a Button control.

I would create a DependencyProperty for each button style in UserControl.

public partial class TemplateUserControl : UserControl
{
    public TemplateUserControl()
    {
        InitializeComponent();
    }

    public static readonly DependencyProperty FirstButtonStyleProperty = 
        DependencyProperty.Register("FirstButtonStyle", typeof (Style), typeof (TemplateUserControl));

    public Style FirstButtonStyle
    {
        get { return (Style)GetValue(FirstButtonStyleProperty); }
        set { SetValue(FirstButtonStyleProperty, value); }
    }

    public static readonly DependencyProperty SecondButtonStyleProperty =
        DependencyProperty.Register("SecondButtonStyle", typeof (Style), typeof (TemplateUserControl));

    public Style SecondButtonStyle
    {
        get { return (Style)GetValue(SecondButtonStyleProperty); }
        set { SetValue(SecondButtonStyleProperty, value); }
    }
}

and then modify xaml for buttons to pick these styles:

now when buttons have to be customized, that can achieved by custom styles:
