Javascript activates server functions
posted

on a dropdown -comboCurrencies,  I attach to client event SelectionChanged.

on  javascript I change items of another dropdown -comboPremium.

The user chooses another item on comboCurrencies.

 on debugging, after the javascript fires, I notice that I reach to the Page_load.

I dont want the JS. to cause me to get to the server function.

Why does this happen?
