Question

I’m assigning a GUID to a form field but it isn’t being submitted with the form.

<asp:HiddenField ID=GuidToken" runat="server"/>

//psuedo code behind

GuidToken = [valid guid];
//check that guid successfully assigned - yes

Once the form is submitted, I extract all form values:

Request.Form["GuidToken"]

Other values come through fine but the above is null. Is this something specific to the guid?

I’m not sure what you are trying to accomplish. But you might want to consider using a session variable to store and ‘pass on’ your token GUID to different pages?

Session["GuidToken"] = myGeneratedGUID;

and later

var retrievedGUID = Session["GuidToken"];

Be sure to check for NULL, Sessions can expire between POSTs.
