Ajax Rating Control - How do I call a server side function w/ multiple controls?

[lamarant]

Hi...I'm trying to use the Rating Control in the Ajax Toolkit in a datalist. I have the control showing up in the list, with the logged in users current rating for each item in the list showing...

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" RepeatLayout="Flow">
     <ItemTemplate>            
             <div class="Rating">
                 <ajaxToolkit:rating ID="SongRating" runat="server"
                     CurrentRating='<%# Eval("USERRATING") %>'
                     MaxRating="5"
                     StarCssClass="ratingStar"
                     WaitingStarCssClass="filledRatingStar"
                     FilledStarCssClass="filledRatingStar"
                     EmptyStarCssClass="emptyRatingStar"
                 />
                 <span class="SmallText">avg: <%# Eval("AVGRATING") %></span>
              </div>
          
     </ItemTemplate>        
</asp:DataList>

When a user clicks on one of the rating controls, how would I go about calling a function (passing in the ID parameter from my datalist) that will execute the stored procedure I have to update the ratings table (I already have the stored proc...just need to know how to call a function with the rating control).

I typically program in VB but I'll understand C# too.

I figured this out. The trick is to use the "Tag" property offered in the rating control.

Here's the sub routine:

Private Sub Rating_Changed(ByVal sender As Object, ByVal e As AjaxControlToolkit.RatingEventArgs)
        Dim SQL As String
        Dim ExecSP As New dbFun
        'run stored procedure
        SQL = "exec RateSong " & _
                "@UserID=" & Request.Cookies("MLKLogin")("UserID") & ", " & _
                "@AudioID=" & e.Tag.ToString & ", " & _
                "@Rating=" & e.Value.ToString
        ExecSP.ExecuteSP(SQL)

End Sub

And here's the rating control:

<ajaxToolkit:rating ID="SongRating" runat="server"
                            CurrentRating='<%# Eval("USERRATING") %>'
                            MaxRating="5"
                            StarCssClass="ratingStar"
                            WaitingStarCssClass="filledRatingStar"
                            FilledStarCssClass="filledRatingStar"
                            EmptyStarCssClass="emptyRatingStar"
                            OnChanged="Rating_Changed"
                            Tag='<%# Eval("AUDIO_ID") %>'
                            AutoPostBack="false"
/>
