copied!<p>STEP 1. There should be a "SubmitRating" button</p> <p>STEP 2. Create a OnSubmitRatingHandling...pseudo code below:</p> <pre><code>private void OnSubmitRatingHandler(...) { IDictionary<int, int> Ratings = new Dictionary<int,int>(); for(int i = 0; GridViewDoctor.Rows.Count; i++) { Label lblDocId = GridViewDoctor.Rows[i].FindControl("lblDoctorId") as Label; sTmp = lblDocId.Text; DocId = Int32.Parse(sTmp); RadioButton rdr1 = GridViewDoctor.Rows[i].FindControl("RadioButton1") as RadioButton; ... same for rdr2/3/4/5 if(rdr1.Checked) { Rating=1; } else if(rdr2.Checked) { Rating=2; } ... Ratings.Add(DocId, Rating} } return; } </code></pre> <p>STEP 3. I don't know why you want save Ratings in Session but not in a disk file or database somewhere? but if this is what you want, then:</p> <p>Session.Add("DoctorRatings", Ratings);</p> <p>But, if you want to persists the information, try add to session a class which include user IP address (Since no login) + rating in session or application variables - such as "UserRating" below</p> <pre><code>public class UserRating { public string UserIP = null; public IDictionary<int, int> Ratings = null; } private void OnSubmitRatingHandler(...) { ... other stuff... string clientIp = (Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? Request.ServerVariables["REMOTE_ADDR"]).Split(',')[0].Trim(); UserRating UserRating = new UserRating(); UserRating.UserIP = clientIP; UserRating.Ratings = Ratings; Session.Add("UserRatings", UserRating); } </code></pre>
