Thanks for the quick response Hans,
Yes, I totally agress with you on the importance of Combobox control,
however most cases are for desktop in-memory application (Office, winform,
.....). For ASP.NET application it is an abstract layer over the raw HTTP
request/response model and HTML elements, most of the ASP.NET controls just
mapped to html elements and some are encapsulate mutiple of the html
elements. And since the HTML model doesn't provide an HTML combobox
element, what we have to do is manually create such functionality through
combining other html element ( input text field and <select> list...) and
script code... However, since mutiple browsers has heterogenous on script
supporting, it makes creating a perfect composite control more difficult.
So what we can do is using the existing controls or elements to make them
work together ( those 3rd party combobox webserver control based on this
...)
Thanks,
Steven Cheng
