Hai Suresh,

Have you tried RadAjaxManager?

ASPX:

    
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadComboBox3"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadComboBox3" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadComboBox ID="RadComboBox3" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox3_SelectedIndexChanged"> 
        
                    <Items> 
        
                     . . . 
        
                    </Items> 
        
                </telerik:RadComboBox>
