Hi there,

I’m trying to databind IronRuby objects to a WPF listbox with no success

My data is a Ruby array of objects. The array seems to be bound fine as  
I see the expected number of rows in the listbox. However, every object  
within the array fails to bind correctly. I tried the object to be a  
Ruby hash or a custom class without success… WPF wouldn’t display the  
correct value.

When I tried to create an array of CLR classes, it worked.

Will it work in the future?

Thanks,  
Shay.

Hi,

Well I reply in the forum even though I don’t see the entire thread here  
for some reason. My emails do not reach the mailing list as well, so…

Anyway, Curt - thanks for the clarification. What you’ve described works  
good with binding of textblocks and links, but when I try to bind an  
image to an IronRuby class attribute it doesn’t work (this works with an  
equivalent C# class).

Is it a bug?

## Thanks for the help! Shay.

I return a String. I have three attributes, all of them hold strings.

Textblock that I bind to the strings work, but when I bind an Image  
element (the Source value) to the string, it doesn’t work.

Hi,

I’ve found a workaround that works - because it’s a string, I convert it  
to a clr string before setting the attribute (str.to\_clr\_string).

Then the picture is bound just fine.
