How to make an event with value in xaml.cs?

I have some RadioButton with Events, I make in the Code behind xaml.cs file. It works find, but I wish to add som value with the RadioButton Click Event. How can I do that?

Code that works

      foreach (ProductLog p in productLogCollection)
      {
       ...
        radioButton[0].Click += ProductBacklog_Click;  // Click Event without value
       ...
      }

Event code works

    void ProductBacklog_Click(object sender, RoutedEventArgs e)
    {
      textBlockError.Text = "Value are: ";
    }

How can I do something like this?

      {
       ...
        radioButton[0].Click += ProductBacklog_Click(VALUE);
       ...
      }

    void ProductBacklog_Click(object sender, RoutedEventArgs e)
    {
      textBlockError.Text = "Value are: " + VALUE;
    }
