Xaml passwordbox binding1/1/2024 ![]() When opening a snapshot in dotMemory, the snapshot overview page will tell us about WPF binding leaks immediately. When profiling an application, we can instantiate the control which binds to our class and then dispose that control. How to detect it?ĭotMemory comes with a series of automatic inspections, detecting common memory leaks. Why is this a problem? Well, since the runtime creates a reference to this PropertyDescriptor, which in turn references our source object, and the runtime will never know when to deallocate that initial reference (unless explicitly told), both the PropertyDescriptor as well as our source object will remain in memory. ![]() If the property is not a DependencyProperty or an object that implements INotifyPropert圜hanged, WPF will resort to subscribing to the ValueChanged event of the class to get notifications when the source object’s property value changes. When we bind to an instance’s Name property, the binding target starts listening for property change notifications. WPF comes with a number of data binding patterns, which, if we break them, can cause memory leaks in our applications. Here are the leaks we will discuss in this post: In this blog post, we’ll see how dotMemory can help detect these common WPF memory leaks and how we can fix them. When developing Windows Presentation Foundation (WPF), Silverlight and Windows Store applications, a number of common memory leaks may surface.
