I am trying to make a small, data-driven widget that is populated with data from a database on the fly. I can load it initially just fine, but when the index of an ASP DropDownMenu is changed, the widget returns a 404.

This could be a symptom of how I am using the Javascript, or how I am using the ASP. I honestly don't know for sure.

Javascript: http://pastebin.com/f127d6b84
ASP: http://pastebin.com/f38c73708
VB.NET codebehind: http://pastebin.com/f7881a903

If the postback is returning 404, I'd look at the url that you're sending the postback to.

Also your widget has some security issues going on, namely SQL Injection.

Dim SelectString As String = "select ListingNumber, ListingSearchHitCount, ListingDetailHitCount, VirtualTourHitCount from FNIS.dbo.ListingHitCountCurrent, RAN.dbo.Heartland_Residential where Heartland_Residential.LIST_AGENT_1_ID = '" & Request("agentname") & "' and Heartland_Residential.MLS_Number = FNIS.dbo.ListingHitCountCurrent.ListingNumber and Heartland_Residential.Status = 'A'"

This inline SQL statement is not parameterizing the Request("agentname") field.
