[IronPython] overriding methods from C# classes

Hello Michael and everyone,

I set out to do just that and stumbled upon a problem:

I generated Windows form in C#, compiled into assembly (ip_cl1), copied 
to python project folder:

clr.AddReference('ip_cl1')
..
from ip_cl1 import Form1


class Form1Inh(Form1):
        def __init__(self):
            Form1.__init__(self)

        def comboBox1_SelectedIndexChanged(self, sender, event):
            self.BackColor = Color.Azure

This doesn't work, i.e. method comboBox1_SelectedIndexChanged doesn't 
get called. I have to expicitly add EventHandler in Python:

class Form1Inh(Form1):
        def __init__(self):
            Form1.__init__(self)
            self.box1.SelectedIndexChanged += 
EventHandler(self.comboBox1_SelectedIndexChanged);

        def comboBox1_SelectedIndexChanged(self, sender, event):
            self.BackColor = Color.Azure


Is there some way of simply overriding methods in Python so that they do 
get called by form events?




In Form1.cs I have:


namespace ip_cl1
{
     public partial class Form1 : Form
     {
         public Form1()
         {
             InitializeComponent();
         }

         protected void box1_SelectedIndexChanged(object sender, 
EventArgs e)
         {

         }

         protected void comboBox1_SelectedIndexChanged(object sender, 
EventArgs e)
         {

         }
     }
}
