Use client side code to get hidden field value from calling page
I have a web application that is being called from an extranet app. I need to access the value of a hidden form variable on the calling form, I have tried Request.form("Fieldname") & cannot pick up any values. They are not keen on passing the value in the querystring - I would really appreciate some help on this.
If the item is not in the form collection, then they're probably not doing a POST to your page.

&nb...Hidden Field that is set on server side...not getting the last updated value from client?
I have a hidden field that tracks errors in my server side asp.net 2.0 code. However, when I set the value to an error (from it's default value "NotSet") in the server side code and then when trying to access that Hidden Variable from the client the value is still set to the default value, "NotSet" instead of the error information.
Any ideas as to what is going on here?
Thanks in advance!
