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
