Scenario:
I have a window that I am using to edit values, has textboxes, the dropdown, and other controls.
Window is opened, textbox loads with the bound value, lets say value = 100.
Change the textbox to say maybe 101.
Select a new dropdown option.
After the dropdown selection is chosen and it's new value binds, it resets the other controls to the original value, so the 101 is back to 100.
