To enable Data binding you need to set the DataContext property of the
object loaded from xaml

you could do something like this
sr = StreamReader(path)
userCtrl = XamlReader.Load(sr.BaseStream)
Content = userCtrl
userCtrl.DataContext = self

Hello,
That is, if the load XAML, as specified below, the Label (Lab1) can be
binding on the CLR type (p.name) is defined in proba.py (do not forget that
the code is the XAML load in proba.py)?

Hello,

I'm not sure about the LoadComponent method but I have used the
XamlReader.Parse(xaml) and it works well for me.

Using something like

sr = StreamReader(path)
userCtrl = XamlReader.Load(sr.BaseStream) Content = userCtrl

Hope that helps;
Pascal

How do I get access to the objects of this class which is loaded XAML.
Given that the objects are presented to the CLR types?
 What namespace should be specified?
 The text below gives an error.

1) module proba.py:
....................................
import WPF
class MyWindow(Window):
# p - CLR type, has a property name
	global p
	def __init__(self):
		wpf.LoadComponent(self, 'proba.xaml')

	def button1_Click(self, sender, e):
		MessageBox.Show(p.name)
....................................
not the entire text of the program

2) file proba.xaml:
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
<!-- This part discusses the -->
        xmlns:local="clr-namespace:proba"
<!-- .................. -->
        Title="Window1" Height="300" Width="300">
    <Grid>
        <Button Name="cnop" Click="button1_Click"/>
        <Label Content="{Binding Source={x1:p}, Path=name}" Height="33"
HorizontalAlignment="Left" Margin="20,12,0,0"
VerticalAlignment="Top" Width="244" Name="Lab1"/>
    </Grid>
</Window>
