Hello!

The only thing that I can come up with is to set the fraction 1/3 as a string "1/3" to the ConverterParameter. After that in the converter you can easily parse the string to the desired double value. Hope that helps!

You could modify converter to expect not simple type as a value but well known for the converter interface. Interface could give all info needed for converter. In this case you don't need to bind converter parameter. See here for more info.

It's still not possible to bind the ConverterParameter in Silverlight. But there is a possible workaround:

If you have a business object with for example two properties - Value and Parameter, and you want to bind to the Value and pass the Parameter to the ConverterParameter. The solution is to bind to the entire business object, so in the Convert() method of the converter you will have access to both the Value and the Parameter properties.

Hope this helps!
