silverlight - Is there an event that fires when a binding is updated? -


is there event fires when binding updated?

for example, i'd create behavior applied combobox every time combobox's itemssource updated.

the simple solution can think of is, when say, want capture itemsource change event. happens when load data or source data associated change, raise property changed event actual data source change , intercept event , ever need item source change.
