copied!<p>I think I've come up with something that may work using simple reflection, and adapting some code I've used in the past (the code for the <code>FindBindingsRecursively</code> method was written by Martin Bennedik's as part of his <a href="http://www.bennedik.de/2007/05/update-of-wpf-integration-for.html" rel="nofollow">Enterprise WPF Validation Control</a>):</p> <pre><code>[TestMethod] public void CheckWpfBindingsAreValid() { // instansiate the xaml view and set DataContext var yourView = new YourView(); yourView.DataContext = YourViewModel; FindBindingsRecursively(yourView, delegate(FrameworkElement element, Binding binding, DependencyProperty dp) { var type = yourView.DataContext.GetType(); // check that each part of binding valid via reflection foreach (string prop in binding.Path.Path.Split('.')) { PropertyInfo info = type.GetProperty(prop); Assert.IsNotNull(info); type = info.PropertyType; } }); } private delegate void FoundBindingCallbackDelegate(FrameworkElement element, Binding binding, DependencyProperty dp); private void FindBindingsRecursively(DependencyObject element, FoundBindingCallbackDelegate callbackDelegate) { // See if we should display the errors on this element MemberInfo[] members = element.GetType().GetMembers(BindingFlags.Static | BindingFlags.Public | BindingFlags.FlattenHierarchy); foreach (MemberInfo member in members) { DependencyProperty dp = null; // Check to see if the field or property we were given is a dependency property if (member.MemberType == MemberTypes.Field) { FieldInfo field = (FieldInfo)member; if (typeof(DependencyProperty).IsAssignableFrom(field.FieldType)) { dp = (DependencyProperty)field.GetValue(element); } } else if (member.MemberType == MemberTypes.Property) { PropertyInfo prop = (PropertyInfo)member; if (typeof(DependencyProperty).IsAssignableFrom(prop.PropertyType)) { dp = (DependencyProperty)prop.GetValue(element, null); } } if (dp != null) { // Awesome, we have a dependency property. does it have a binding? If yes, is it bound to the property we're interested in? Binding bb = BindingOperations.GetBinding(element, dp); if (bb != null) { // This element has a DependencyProperty that we know of that is bound to the property we're interested in. // Now we just tell the callback and the caller will handle it. if (element is FrameworkElement) { callbackDelegate((FrameworkElement)element, bb, dp); } } } } // Now, recurse through any child elements if (element is FrameworkElement || element is FrameworkContentElement) { foreach (object childElement in LogicalTreeHelper.GetChildren(element)) { if (childElement is DependencyObject) { FindBindingsRecursively((DependencyObject)childElement, callbackDelegate); } } } } </code></pre>
