protected virtual void Form1_KeyDown(object sender, KeyEventArgs e)

type.InvokeMember(node.Attributes["event"].Value, BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic, null, obj, new object[] { null, null });
}
}
}
private void Form1_Load(object sender, EventArgs e)

if (nodeForm != null)

}
}
catch
