Hi there - I am developing a module that uses a jquery plugin (jqGrid) and I'm having trouble accessing some variables that it posts to the form.  Basically, I'm making an ajax call to an .asmx web method. I don't have any trouble getting data returned to the client, but I am trying to access the form variables, and they are always null in the method. 

Using Firebug I noticed that the form variables are posted like this: 

GET http://localhost/DNN5/?nd=1239298661096&_search=false&rows=2&page=1&sidx=PartnerID&sord=asc

 I can see this in the response:

  <form name="form" method="post" action="/DNN5/Default.aspx?nd=1239298661096&amp;_search=false&amp
;rows=2&amp;page=1&amp;sidx=PartnerID&amp;sord=asc" id="form" enctype="multipart/form-data">

Then this call is made: 
POST http://localhost/DNN5/EDI.asmx/GetTableData
 
Here is my webservice excerpt trying to access the variables:

 'If Not HttpContext.Current.Request.form("nd") Is Nothing Then
        If Not HttpContext.Current.Request.Params("nd") Is Nothing Then
            objPostDataInfo.ND = HttpContext.Current.Request.Params("nd")
        Else
            objPostDataInfo.ND = Date.Today.Ticks
        End If

There is apparently some knowledge on this subject that I am lacking and I am hoping someone can help me out here. How do I access those form variables? Thanks so much!
