Hello. I am trying to make a small WPF app that will let me view images and text contained in an xml document. I have all the binding set up. Now I am trying to find a way to load a new xml file (same schema). I am trying to use the OpenFileDialog to specify the source property of the XmlDataProvider shown in my XAML to do this. The app compiles no problem, but nothing changes when I “open” a new xml file. Any help would be great!
