RadComboBox for ASP.NET AJAX SelectedIndexchanged issue

[Mohamed]

Hello Telerik Team

Currently I'm using RadControl version : 2011.1.315.35 (for ASP.NET AJAX). After doing research a lot on this forum and the Internet, I still can not solve my issue so I post here.

My ASPX file :

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage/DownloadCenter.Master" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="DownloadCenter.GUI.Test" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<asp:Content ID="Content1" ContentPlaceHolderID="contentPage" runat="server">

    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>

<telerik:RadComboBox ID="rd" runat="server"
            EnableLoadOnDemand="True"
            DataTextField="Desc"
            DataValueField="PayID"
            OnItemsRequested="RadComboBox1_ItemsRequested"
            AutoPostBack="True"
            onselectedindexchanged="rd_SelectedIndexChanged"
            >
        </telerik:RadComboBox>
</asp:Content>

My code behind looks like

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using DownloadCenter.Entity;
using Telerik.Web.UI;

namespace DownloadCenter.GUI
{
    public partial class Test : System.Web.UI.Page
    {
        BO bo = new BO();
        DB db = new DB();
        User user;


        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                BindRD();
            }
        }

        private void BindRD()
        {
            rd.DataSource = db.GetPayMethod_CB();
            rd.DataBind();
        }

        protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
        {
            rd.DataSource = db.GetPayMethod_CB();
            rd.DataBind();

        }

        protected void rd_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            string tt = rd.SelectedValue.ToString();

            Session["SupplierID"] = e.Value;
        }


    }

The very first issue I face is : when I select "aaa" the comboBox will automatically select "bbb". But this issue i already resolved by using

<script language="javascript">

    function onBlur(comboBox) {
        comboBox.OriginalText = comboBox.GetText();
    }
</script>

Now when I select "aaa" it will display "aaa" but I don't know why the SelectedIndexChanged event won't fire.
Please notice that
            DataTextField="Desc"
            DataValueField="PayID"
has unique value and it differs from other field.

I already follow many work around here but i still can make it.
Please help me out.
Many thanks in advance

Pasha

I was not able to find where you use the onBlur function in your code - maybe you handle OnClientBlur event?

Have you debugged your code - does the page rise a postback after you change the selected item?

Are there any javascript errors on your page?
