Two-way binding requires path or xpath?

I think that Binding is not necessary. Try to delete it and change indexes in converter.

I want to increase Progress-bar value based on two textbox`s Text. I write this XAML but here is an error "Two-way binding requires path or xpath" when I do MultiBinding in ProgressBar. Value Value Converter : public class Class1 : IMultiValueConverter { public object Convert(object values, Type targetType, object parameter, System.Globalization.

CultureInfo culture) { if (values1! = null && values2! =null) { if (((string)values1).

Length==((string)values2). Length) { return 5.0; } } else { return 0.0; } } public object ConvertBack(object value, Type targetTypes, object parameter, System.Globalization. CultureInfo culture) { throw new NotImplementedException(); } } c# wpf xaml data-binding link|improve this question edited Oct 3 '11 at 8:17H.B.43k61645 asked Oct 2 '11 at 17:40Vero0092498 64% accept rate.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
