Hey Actipro Community,

I have an app where a user will close, open and load a new workspace. I have one tool window on the side. If I close and open a new workspace, the contents of the tool window are not updated appropriately.

Upon closing my workspace and opening a new one, I update my collection that is bound to ToolItemSource in the XAML with a new viewmodel. However the change doesn't bubble up to the view. Why don't the Tool Windows update when the tool item source changes?

Hi Aaron,

It's difficult to say without seeing a small sample of what you are doing.  If you'd like us to look, please make a new simple sample project that shows the issue and email it to our support address in a renamed .zip file extension so it doesn't get spam blocked.  Reference this thread in your email.  Other than that and in the meantime, you can look at our samples since some of them show MVVM implementation such as using ToolItemsSource.
