Hi, I want to use Post Url Wokflow in Ms CRM 3.0 with passing parameter. I had do that with select the field to post into a url (in the OnCreate Order). For example the url is "http://localhost/Default.aspx" and the selected field is Order ID. I try to Request.QueryString ["Order ID"], but value of the order id not filled. How can I get the value of the field which the crm post ?
