(Silverlight newbie) Trying to add custom object as a Child of a WrapPanel (on code behind)

Question

I have a WrapPanel where I add a bunch of rectangle controls I got everything working, but now I have decided that it would be better to create a class for them and instead of creating rectangles all over the place I'll just instantiate new objects.

I did it but the problem is that now I get an error when I try to add my object as a Child to the WrapPanel or anywhere for that matter.

Error: The best overloaded method match for 'System.Windows.PresentationFrameworkCollection.Add(System.Windows.UIElement)' has some invalid arguments

I tried extending my class with the UIElement class

 public class myColor : UIElement {...}

this didn't work either as I'm missing the constructors for the UIElement class Error:

The type 'System.Windows.UIElement' has no constructors defined

I'm still learning Silverlight and c#, any help would be appreciated it, Thanks

Answer 1

I don't believe the UIElement class can be extended. You could use extension methods or you could try inheriting from a FrameworkElement.

Answer 2

Silverlight does not allow you to inherit UIElement as it is possible in WPF. You can inherit from FrameworkElement or take it one step further and inherit from Control.
