I'm looking for an elegant way to track changes between values for a combo box. What I'm looking to do is fire a custom event when the SelectionChanged event happens, but only for a specific value changes. This implies knowing what the initial value was. The event will only be fired when the initial value is changed from z. If the initial value is a, b, or c, the event will not be fired. But if the initial value was z, it will be fired.
Does anyone have an elegant way to solve this problem?
For this you will have to create a custom event handler and may be custom event args,

Haven't compiled the code, but logically it should work for you.
