Hi,
We need to change the appearance of tree items at runtime. We've used a HierachicalDataTemplate and within it have an image bound to a valueconvertor which displays the appropriate image depending on the underlying value in an ObservableCollection.
This works great on the first load of the tree item. However, when changing underlying value doesn't change the appearance of the tree item. It seems the valueconverter code only gets called on the initial display,
How else can I change the appearance of my tree item at runtime?
Thanks, Paul.
