Add DataBinding for attached Property per Code Behind
11,892
It's somewhat unclear from your question, but I think you're asking how one would bind to the attached property Canvas.Left
and show it in a TextBox. I'll assume you want it for a control other than the TextBox.
<Canvas>
<TextBox x:Name="textBox" Text="{Binding ElementName=button, Path=(Canvas.Left)}" />
<Button x:Name="button" Content="Press me" />
</Canvas>
Note the brackets around the attached property.
EDIT: To do the equivalent in code, use the following:
Binding binding = new Binding();
binding.Source = button;
binding.Path = new PropertyPath(Canvas.LeftProperty);
textBox.SetBinding(TextBlock.TextProperty, binding);

I want to add a DataBinding per Codebehind for an attached Property and want to show the
Canvas.Left
property in a TextBox. How do I add this property? -
Matze about 14 yearsCode binding does not work as in sample code. Third line should read like binding.Path = new PropertyPath(Canvas.Left);
