All,

I posted this on StackOvervlow, but I thought I would notify this list  
of my  
question, in case someone here understands what is going on…

Basically, I am finding that data binding to properties on IronRuby  
objects  
works for some controls, but fails on others. I have an example of it  
here:

Anyone have any idea why this happens?  
Brian

I find IronRuby types hard-to-work-with sometimes when it comes to WPF  
data  
binding. What I do as a workaround is creating the data entity classes  
in C#  
and initialize them from IronRuby code.

To fix your sample WPF app, I used the CLR string instead of IronRuby’s.  
So  
instead of:

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

```

You need to do:

```
def initialize
  @ImageLocation =

```

“[http://www.ironruby.net/@api/deki/site/logo.png](http://www.ironruby.net/@api/deki/site/logo.png)”.to\_clr\_string  
end
