Question

I create a Textbox in Code behinde and bind it to a double Property.

                TextBox t = new TextBox();
                t.Width = 80;
                t.DataContext = s;         
                Binding binding = new Binding();
                binding.Mode = BindingMode.TwoWay;
                binding.Path = new PropertyPath("Value");
                BindingOperations.SetBinding(t, TextBox.TextProperty, binding);

When I enter a value like 45,45 (comma) it is parsed to 4545.

If I enter 45.45 (point) it is parsed correctly with 45,45.

I use German language Settings and my decimal separator is ,.

What am I doing wrong?

Try setting binding.ConverterCulture to your target culture.

For example

 binding.ConverterCulture = CultureInfo.CurrentCulture;
