Wpf treeview binding not updating
Here are links to a couple of them: Thread 1: Observable Dictionary, problem with Remove Thread 2: Bind observable dictionary As promised in my response to the latter thread, I am now providing a sample demonstrating how one might implement an observable dictionary. The Observable Dictionary Sample In this sample, I demonstrate how to bind to a dictionary of button styles.
The styles are sorted based on their Key values in the observable dictionary.
As a result, an attempt to create an observable dictionary by deriving from or aggregating a dictionary won’t work.As you click around, you will notice that the bound controls respond appropriately to any changes in the observable dictionary. You may now want to provide a view of the dictionary entries in your user interface.Unfortunately, to provide a dynamic view of your dictionary data, you would need to do a lot of extra work.Namely, you would need to write code to synchronize some observable collection with your dictionary whenever you modify it.Wouldn’t it be nice if the dictionary, itself, were observable?
The Two List Synchronizer code does not make especially thrilling reading, so I won’t show it here.
