Hello,
I'm trying to bind the SelectedItem of the RadComboBox. I need to pass the ItemsSource of the combobox to the Converter used for Selected Item. Everyt time I try to bind anything to the ConverterParameter, I get the following when parsing the xaml in InitializeComponent:
{System.Windows.ApplicationUnhandledExceptionEventArgs}
base {System.EventArgs}: {System.Windows.ApplicationUnhandledExceptionEventArgs}
ExceptionObject: {System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Windows.Markup.XamlParseException: Provide value on 'System.Windows.Data.Binding' threw an exception. [Line: 101 Position: 98] ---> System.InvalidOperationException: Operation is not valid due to the current state of the object.

Handled: false
My latest attempt at binding is:
No errors if I leave out the ConverterParameter, but then my Converter won't function correctly. The same binding works correctly for the ItemsSource.
Thank you,
