Binding RadioButton to Dictionary

Question

Currently I have a RadioButton that is bound to a generic type... TestObject<T>

In this object, I have a property called Value which can be either 1 or 0. I have a property called MyList which is a Dictionary<T,String> which holds the following values:

   INT          String
    0            "This is the first option"
    1            "This is the second option"

What I am having trouble doing binding the RadioButton to MyList. Currently I have IsCheck ed bound to Value (with a converter to return true/false). My biggest issue is the dictionary and how to bind it to the RadioButton control so I can see 2 RadioButton options on the screen.

Any ideas?

Why dont you use a List of KeyValuePairs or Tuples instead of a Dictionary?

Then you could use the ItemsControl, put the RadioButton in your DataTemplate and bind the ItemsSource to you List of KeyValuePairs.

Try filling the radio buttons during runtime.

Here's an example using WPF:

    private RadioButton CreateRadioButton(RadioButton rb1, string content, Thickness margin, string name)
    {
        //private RadioButton CreateRadioButton(RadioButton rb1, string content, Thickness margin, string name)
        // We create the objects and then get their properties. We can easily fill a list.
        //MessageBox.Show(rb1.ToString());

        Type type1 = rb1.GetType();
        RadioButton instance = (RadioButton)Activator.CreateInstance(type1);

        //MessageBox.Show(instance.ToString()); // Should be the radiobutton type.
        PropertyInfo Content = instance.GetType().GetProperty("Content", BindingFlags.Public | BindingFlags.Instance);
        PropertyInfo Margin = instance.GetType().GetProperty("Margin", BindingFlags.Public | BindingFlags.Instance);
        PropertyInfo Name = instance.GetType().GetProperty("Name", BindingFlags.Public | BindingFlags.Instance);
        // This is how we set properties in WPF via late-binding.
        this.SetProperty<RadioButton, String>(Content, instance, content);
        this.SetProperty<RadioButton, Thickness>(Margin, instance, margin);
        this.SetProperty<RadioButton, String>(Name, instance, name);

        return instance;
        //PropertyInfo prop = type.GetProperties(rb1);
    }

    // Note: You are going to want to create a List<RadioButton>
