Refresh a combobox without postback
First I must say that I am not very experienced with web development.
On the other hand, I am writing a web application and I need to refresh data in a combobox without a postback?
Is this possible in an ASP.NET web application?
I am not on an intranet. I am developing an webpage were I collect Elements - Property - Value pairs, with 3 comboboxes. The third combobox (values) depends on the selection of the first (Elements) and the second (Properties) and the history of items selected in the same session. Some combinations are not possible, therefore I collect all the previous selections made in an XML document. Send to the server, server reply with an additional section of values for the third combobox (values still allowed due to the previous selections made).
Is this possible without a refresh of the webpage (postback)??
Or should I write an ActiveX for this application?
