I have a page with a graph who got its data from a xml data source. I also have a dropdownlist that filter out the xml result after a postback. I want this filtering being done without a postback (querystring)... as I understand I can perform this with ajax? Some help are welcome.. :-)

You can use UpdatePanel and AsyncPostBack to the dropdownlist Item Changed.
and you can refresh the graph accordingly

hmm ok.. u have some code or pseudocode of how to make the dropdown-postback update the updatepanels graph with the new values? the graph loads it's data through a xml data stream (webservicexml.aspx (yes a webform))
