Hi all, I'm writing my very first Silverlight app. I have a datagrid with a column that has two labels, for the labels, i am using an IValueConverter to conditionally format the data.

The label's "Content" is set as such:

Content="{Binding HomeScore, Converter={StaticResource fmtshs}}"

and

Content="{Binding AwayScore, Converter={StaticResource fmtshs}}"

The Convert method of my IValueConverter is such:

Public Function Convert(
  ByVal value As Object, 
  ByVal targetType As System.Type, 
  ByVal parameter As Object, 
  ByVal culture As System.Globalization.CultureInfo) As Object 
Implements System.Windows.Data.IValueConverter.Convert

    Dim score As Long = value, other As Long = parameter

    Return If(score < 0, "", 
        If(score - other > 5, (other + 5).ToString, score.ToString)
    )

End Function

So what i want to do is in the converter for HomeScore, i want to pass AwayScore to the ConverterParameter, and for AwayScore i want to pass the HomeScore to the converter. In the converter for either score i need to be able to know the value of the other score for formatting purposes.

But i cannot figure out the syntax for binding the ConverterParameter to another field.
I've tried the following:

Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter=AwayScore}"  
Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={AwayScore}}"  
Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={Binding AwayScore}}"

But none of those seem to work. How do i pass a field value to the ConverterParameter?
