Question

Is there a way to get the selected value (or text, or index) of a select box that the server fills (using ASP.NET) in the client? I’ve tried $(“#ID”).val() – but the only time that works is when I continue to another page and then go back. Even then, the value that is returned is the previously selected value – if the user changes the selection, it’s not registered unless they leave the page and go back. Go easy on me, I’m new at this…

Update: Tried using a regular html select, same issue (just with a populated entry). Let me elaborate on what I’m trying to do: in a separate page, I’m getting results for an autocomplete search box. The select boxes are for filters. Naturally, if the user selects a filter, I don’t want to suggest items that are no longer valid. I’m looking for the keys in the ProcessRequest method of the page that contains autocomplete info.

public override void ProcessRequest(HttpContext context)
    {
        string respString;
        string qsKey = "q";
        Customer searchCust = Session[Data.Selected_Customer] as Customer;
        Dictionary<string, string> qsDict = context.Request.QueryString.ToDictionary(qsKey);

Shouldn’t I get the results (for instance ‘&ID=foo’ on the last line @ context.Request.QueryString?

If you want the actual selected item itself:

$("#ID option:selected");
