Wpf itemssource binding not updating

Default is, obviously, the default value of the Update Source Trigger.The other options are Property Changed, Lost Focus and Explicit.If we don't open the drop down first (skip steps 2 and 4), then all items will appear correctly in the drop down.Yeah, you need to open it to check the items, so after that all new items will not be added immediately.Sometimes the new item appears in the drop down though, even if the drop down has been opened and closed first. As you see, there is nothing special, just as simple as possible.Though the WPF Combo Box displays its items properly while the Fluent Ribbon Combo Box does not (in that use case as described: first open the drop-down, then add items).The first two has already been described, while the last one simply means that the update has to be pushed manually through to occur, using a call to Update Source on the Binding.

Could you try to reproduce this with the current version from the develop branch?Modify the constructor for the Main Window class to set an instance of the class as the data context for the window: The syntax is no different from the binding expressions we've seen in earlier articles. You should find that the three items set in the data object's constructor are displayed in the List Box.
