I am having an intersting issue to which I have found no solution, obviously. I am using a web service to populate a couple cascading drop downs. Evereything looks correct to me but I am getting a [Method Error 500] when I run it all. I have the <System.Web.Script.Services.ScriptService()> added to the web service so that's not the problem. What I have found while playing with it is that if I remove the arguments from the web method (ByVal knownCategoryValues As String, ByVal category As String) then it works. This of course is not helpful as I am trying to populate multiple drop downs. I can find nothing on anyone else having this issue.
I am using .NET 3.5 and Ajax DLL version 3.02...
Also of note is that I have another website, using the same .NET and Ajax versions and this code is working fine.
I have tried everything I can think of, including my last resort tactic of smashing my face on my keyboard, and nothing is working. I am at a loss. Any help would be appriciated. Thanks.
<asp:DropDownList runat="server" ID="ddlPlateType" Width="250px" />
<ajax:CascadingDropDown runat="server" ID="cddPlateType" TargetControlID="ddlPlateType"
