Raising a custom event
There are a number of drop-down controls on my page, as well as a data list that is filtered based on the content of the drop down controls.
If any one of the drop downs change, the data list has to be re-filtered. I can attach a "Changed" event handler to EVERY drop down - but that is tedious to maintain.
I thought that as each drop-down changes I could cause another special event handler to fire - but I found that my attempts were unreliable.
Is there a reliable way to handle this? (I have found the ability to raise custom events very useful in other prototyping tools.)
