    <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&lt;int, int&gt; Ratings = new Dictionary&lt;int,int&gt;(); 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&lt;int, int&gt; 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>

    1. COI wanted to store the ratings in Session, because users will be able to rate their favorites, and the doctors for the favorites need to be stored in session, so I figured the ratings should be stored in session.

    2. COYes I can see that users are to enter rating for each doctor in the GridView - but after user enter ratings in the form, user probably need hit submit, then ratings would be saved on server side right? For example to calculate average ratings per doctor over some number of submissions?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
