Wpf combobox itemssource binding not updating

Or maybe not – the reason behind this is not entirely clear to me.

I was recently creating a simple WPF application and was trying to use the MVVM pattern.

If I add a Break Point to the Setter, it is only fired when the collection is initialized, and NOT when an item is added to the collection. All is currently running on the same thread, but I'd also like to look at putting the Get All Server method into a Task. Start New so it runs on a different thread and doesn't interrupt the UI animation, but when I do this the Servers collection is populated, but the Combo Box on the UI isn't updated.

So, The main problem is the Databases collection not updating the UI when an item is added.

I would be interested to hear in the comments if you think either approach has benefits over the other.

One consideration is that Silverlight doesn’t seem to support Collection View at the moment.

It runs the filter method allright but the View wont update even with my Collection View. I really liked Collection View approach so would be nice i could stick to that.

To answer your question: from my point of view your suggestion is almost an imperative if one applies the MVVM pattern on comboboxes. Michael Schlegel Hi Mark, Great posts, I read your post about MVVM List Box filtering, what i´m looking for is something in between.Hi, I have an Observable Collection in my View Model that I'm binding to the Items Source of a Combo Box.The problem I'm having is in the Get Databases method where it adds a string to the Database collection.What I wanted to do was bind the items in the Combo Box to a list in my View Model and to track the currently selected item.I found that there does not seem to be one “official” way of doing this.

embed=snippet 8255492] the setter is not supposed to fire when an item is added, since you collection is of type observable, it should update the UI.
