Hello Mohamad,

Note that you don't need to handle the GridView's RowCommand event in order to reference the rating control. If you set the AutoPostBack property of RadRating to true, the control will initiate postback when you click any of its items and you will be able to handle its server-side event Rate. In the handler of this event you can get the value of the clicked RadRating and you can update the database accordingly.

Page

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" ShowHeader="False"
    BorderStyle="None" GridLines="None" Width="100%">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <telerik:RadRating ID="RadRating1" runat="server" SelectionMode="Single" AutoPostBack="true" OnRate="RadRating1_Rate" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Code-behind

protected void RadRating1_Rate(object sender, EventArgs e)
{
    RadRating rating = (RadRating)sender;
    Response.Write("You voted with " + rating.Value); // here you can update the database with the new value
}

The online demo Rating / RadRating in RadGrid shows the overall approach for achieving the desired functionality. It can be used as the implemented scenario is quite similar to your case.

I would suggest creating separate forum thread for each problem you want to report in the future. This way the updates on the current case will be much easier to track. That being said, let us continue the discussion in your initial forum thread.

All the best,
