Hi,
I have a page which will have the rad rating control.

Actually i am trying to get the selected value while user clicks on the rating item.

This is my aspx page code

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="testpage.aspx.cs" Inherits="testpage" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

                        </Items>
        
                    </telerik:RadRating>

    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /><br /><asp:Label ID="Label1" runat="server"
        Text="Label"></asp:Label>

  

    </form>
</body>
</html>

Here is my Code behind

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections.ObjectModel;
using System.IO;
using System.Drawing;
using Telerik.Web.UI;
public partial class testpage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        
    }
  
    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = ratingBar.Value.ToString();
    }

    protected void RadRating1_Rate(object sender, EventArgs e)
    {
        Label1.Text = ratingBar.Value.ToString();
    }
}

I can able to get the selected value on button click.

But the Onrate is not working.Even in debug mode I checked.

The OnRate event is not fired while clicking on the Rating control.

Please can any one suggest me how to proceed with this.

Thanks in Advance

Hello Thenmozhi,

In the code sample that you provided I noticed a couple of inconsistencies.
  1. The RadScriptManager must be inside the form, otherwise there will be a runtime error -  "System.Web.HttpException: Control 'RadScriptManager1' of type 'RadScriptManager' must be placed inside a form tag with runat=server."
  2. Set the ItemCount property value to 6 (the number of items in the Items collection).
Apart from this, the example works just fine. Please, find attached the modified aspx file and try rerunning the example with it.

If you continue to experience problems with the event's behavior, please, provide a sample working project to be able to reproduce it.

Kind regards,
Nikodim

Hello Thenmozhi,

Could you check the version of the RadControls that you are using and let me know if they are not the latest? It is because I have tested this scenario with the latest version and no problems occurred.

Please, find attached a sample project with an example implementation of the RadRating OnRate event. Try running the Default.aspx page.
  • Clicking on the RadRating control (choosing a new value) should fire the OnRate event, populating the Text property of the Label.
  • Clicking on the Button should result in firing its click event. The content of the Label should be different, but the value of the RadRating should still be present.
Please, let me know of the outcome.

If you need an example solution for using RadRating inside a RadGrid, you could refer to the Telerik demos Application Scenario - "RadRating in RadGrid".

Best wishes,
Nikodim

Hi Thenmozhi,

Please, make sure that there are no javascript errors (this may prevent the postback to the server, i.e. the OnRate event). If there are any errors, being client or server side, you can send the logs from them. Still the best options will be to send me a sample project that reproduces the problem in order to investigate it in depth.

Nikodim

Hi,

I am facing this small issue. the thing is that i want to display the average rating from the database (sqldatabase). i just cannot figure it out how can i bind the radrating to sql in order to insert and display the average value. i read your databinding section of the radrating, won't be able to  figure ItemBinding.ValueField property.  What i want it to do is that OnRate i want to insert the value in the database and then show the average voting.

This is my aspx page code


<form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
   
    <telerik:RadRating ID="ratingBar" runat="server" AutoPostBack="True"
        ItemCount="6" OnRate="RadRating1_Rate" Orientation="Horizontal"
        Precision="Item" Skin="Outlook" Width="100px">
    </telerik:RadRating>
    <br />
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
    <br />
    <asp:Label ID="lblAverageRating" runat="server" Text="Label"></asp:Label>
     
    </form>


Here is my Code behind

protected void RadRating1_Rate(object sender, EventArgs e)
        {
            Label1.Text = "Your Current rating is: " + ratingBar.Value.ToString();
        }

With Label1 i can display the current rating and below that label i have lblAverageRating where i want to display the average vote.
Sql database is very simple, the database file is RadRating.mdf and has one table called Vote. The table has 2 columns: ID and Rate.
From the Rate column i have to extract the average rating.

thank you so much in advance. z.

Hi Thenmozhi,

Please, refer to the demos for RadRating, namely the one with the RadGrid - http://demos.telerik.com/aspnet-ajax/rating/examples/gridrating/defaultcs.aspx. This demo show how to implement average ratings using the RadRating within RadGrid, utilizing the OnRate event of the RadRating control. Hope this will be of help.

All the best,
Niko

Hello Zura,

You can handle the Rate event of RadRating in order to set its property ReadOnly to true and create a flag that indicates whether the user has rated. On the Page_Load event this flag will be used to set ReadOnly to true if the rating was used before the postback. The following code demonstrates this approach:
<telerik:RadRating ID="ratingBar" runat="server" AutoPostBack="True"
    ItemCount="6" OnRate="ratingBar_Rate" Orientation="Horizontal" Precision="Item"
    Skin="Outlook" Width="100px">
</telerik:RadRating>

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["rated"] != null)
    {
        ratingBar.ReadOnly = true;
    }
}
 
protected void ratingBar_Rate(object sender, EventArgs e)
{
    Session["rated"] = true;
    ratingBar.ReadOnly = true;
}

All the best,
Slav
