Expose parameters for my user control in top level XAML Layout ?

Suppose I have a usercontrol "myButton"

I want someone to be able to use this control it in their XAML layout with

<some container>
<local:myButton param1="value1" param2="value2" />
</some container>

I want param1 etc to hold a values (integer, string or Brush) that will be
used in the layout of the control in the XAML but also available to the
usercontrol code behind.

How do I go about setting up these parameters in the "myButton" definition ?
Simply having a property (or a dependency property) in the XAML/c# code for
the control doesn't seem to make these parameters accessible.

I think you are looking for attached dependency properties. Look into the
documentation, it's the same concept behind Grid.Row or Grid.Column
properties.

Griff,

Perhaps you need to add CLR wrappers around the property? I've seen
that recommended in most custom control development documentation that
I've seen (which is scant!).

For example:

public class CustomControl : UserControl
{

// Dependency Property
public static readonly DependencyProperty Param1Property =
DependencyProperty.Register("test", typeof(int),
typeof(CustomControl), etc...


// CLR wrapper for DP
public int Param1
{
get { return (int) GetValue (Param1Property); }
set { SetValue (Param1Property, value); }
}

}

Yes, you need static set and get methods for any attached property as Jason
recommends.
