Question

So, lets say I have two nearly identical classes in C# and Ruby:

C#

public class Test
{
    public Test()
    {
        ImageLocation = "http://www.ironruby.net/@api/deki/site/logo.png";
    }

    public string ImageLocation { get; set; }
}

Ruby

class Test
    attr_accessor :ImageLocation

    def initialize
      @ImageLocation = "http://www.ironruby.net/@api/deki/site/logo.png"
    end
end

When I bind to the “ImageLocation” property in C#, all three controls bind properly. When I bind to the same property with the IronRuby object, it works for TextBlock, but fails for TextBox and Image. Here is my XAML:

<Image Source="{Binding ImageLocation}" Width="50" />
<TextBlock Text="{Binding ImageLocation}" />
<TextBox Text="{Binding ImageLocation}" />

Why does the binding work properly for one control, but not the others?

IronRuby types have a few problems with WPF binding… let’s say that it’s not perfect yet 🙂

To solve your problem, I recommend you to use CLR classes and types. For example, to make your sample code work just convert this line:

@ImageLocation = "http://www.ironruby.net/@api/deki/site/logo.png"

To this:

@ImageLocation = "http://www.ironruby.net/@api/deki/site/logo.png".to_clr_string
