Eto - Dropdown binding fails on Mac

So, I have a nice little Eto dropdown that should get populated from a list with custom objects.

The following code works in Windows (RH6), but fails in Mac. In the latter, instead of text values, the control shows the object type.

class MyObject
{
        public string Key { get; set; }
        public string Name { get; set; }
}

//---------------------

List<MyObject> myObjects = new List<MyObject>();
// ... fill list

var selector = new DropDown
            {
                DataStore = myObjects,
                ItemKeyBinding = Binding.Delegate<myObject, string>(a => a.Key),
                ItemTextBinding = Binding.Delegate<myObject, string>(a => a.Name),
            };

In Mac, the selector shows the type name instead of the name values:

MySolution.MyObject
MySolution.MyObject
MySolution.MyObject
MySolution.MyObject
MySolution.MyObject

Is this a bug or am I missing something?

It sounds like a bug to me, but you’re probably better off reporting it directly on GitHub
https://github.com/picoe/Eto/issues as it seems not Rhino-related.

@curtisw, is this something you can confirm (or deny)?

Thinking about it, I knew I ran into this recently, and it is already in the issues list

The solution is to override the ToString() for the display code; in your case you may have to do some more to get it right.

Thank you, Menno.

For the time being, I was able to make a rather clumsy workaround by assigning the string values directly via selector.Items.Add(...)

Yeah this is a known problem as @menno pointed out. I didn’t know it had the same problem on OS X, so thanks for letting me know!

I’ve updated the issue to reflect this.

Thanks!
Curtis.
