Hi,

I want to filter records that display in some asp.net dropdownlists without causing a postback. Any ideas?

e.g. when the selectedindexchange event fires for dropdownlist1 then only certain records are displayed in dropdownlist 2. I know how to add a client side javascript event to the dropdownlist but I dont know how to..

1: Filter out records in dropdownlist2 without a postback
2: Whats the best way to handle the data that is returned from the database that is used as the source for the dropdownlists. e.g. Return a dataset, store into a session variable and write javascript to populate an array? I'd need 2 arrays, one for each dropdownlist...

Any code examples or previous experience most welcomed.

Thanks
A
