[sign_seventh]

how can i used the web cache in dropdown box..i have 2 dropdownbox, dropdown1 w/ 5 list item. (autopostback=true)<asp:listitem>1<asp:listitem>2</asp:listitem>etc.in dropdown2, value will be depending on the item that will be selected on dropdwn1.sample;if i select in dropdown1 the "1", it will query all records with no. "1" then it will be post in dropdown2..and vice versa when i select the "2", my problem is when i select again the "1", it will query again the records in the dbase, and it really takes a long time to load the page again...how can i use the cache to past the of records with "1" in the cache, and then use it again when i need..it will a lot easier to load the page cause the data is already in the memory rather than getting it from database again and againthnx

I guess the solution to your problem could be using AJAX, its better than relying on cache for faster page load.using AJAX only the required part of the page is reloaded.
