Wpf textbox text binding not updating
This isn't a major problem unless your app is updating large strings to text boxes over many iterations.The main reason to note this behavior is because it can often show up on memory profile traces and there is no point being distracted by it.
Note: 2008 and older issues are only available as files.
I had some extra time this weekend, so I refactored one of my early looping panels into something that might be useful for a wider audience.
This post also includes a simple demo showing how the Loop Panel can be used as the items host of a custom List Box class.
NET framework now takes care of freeing objects for you, and is also ultra-cautious. void On My Cut Handler (object target, Executed Routed Event Args e) void On Can ICut (object sender, Can Execute Routed Event Args e) This code leaks because we are leaving a strong reference in the main As a result, even when the child closes, it will still remain in memory. Tracing it backwards using ANTS Memory Profiler shows that the User Control as the source of the leak.
It works out whether it thinks a particular object is going to be needed while your program runs, and it will only release that object if it can completely guarantee that that object is not going to be needed again. Improper use of the Dispatcher Timer will cause a memory leak. The problem is, once again, a reference being held, this time by the Dispatcher, which holds a collection of live Dispatcher Timers.
