We have the following scenario in our application.

The page's DataContext is an instance of "MyDataObject".
The grid's ItemsSource is a property of "MyDataObject" called "Results".
"Results" is defined as an "ObservableCollection<object>". Each item in "Results" is actually a "Dictionary<key,value>" pair.
Each column is bound to the same converter, which will parse the Dictionary for a specific key based on the converter parameter...

To visualize...

    
            Results[0] = { {"name", "Rob"}, {"age", "17"}, {"country", "Canada"}  }; 
        
            Results[1] = { {"name", "Dave"}, {"age", "5"}, {"country", "England"}  }; 
        
            Results[2] = { {"name", "Mary"}, {"age", "31"}, {"country", "Australia"}  };

The datagrid columns are defined as follows...

    
            <rg:GridViewDataColumn DataMemberBinding="{Binding Converter={StaticResource MyConv}, ConverterParameter='name'}" /> 
        
            <rg:GridViewDataColumn DataMemberBinding="{Binding Converter={StaticResource MyConv}, ConverterParameter='age'}" /> 
        
            <rg:GridViewDataColumn DataMemberBinding="{Binding Converter={StaticResource MyConv}, ConverterParameter='country'}" />

And my converter is as follows...

    
            public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
        
            { 
        
                Dictionary<string, object> x = (Dictionary<string, object>)value; 
        
                return x[parameter.ToString()]; 
        
            }

I'm trying my best to replicate this problem outside of our solution and having a difficult time... If we create the columns dynamically, the user will crash the browser by scrolling horizontally. Creating the columns directly in XAML, or creating the columns dynamically after inserting a blank column in XAML works fine.

Has anybody seen behavior like this before?
