                    <telerik:RadAjaxPanel ID="rapProjects" runat="server" ClientEvents-OnResponseEnd="ProjectsResponseEnd" >
                        <telerik:RadComboBox ID="rcbProjects" runat="server"
                            OnClientDropDownOpening="InitiaterapProjectsRequest" >

                    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server" >

                        <script type="text/javascript">
                            function InitiaterapProjectsRequest(sender, eventArgs) {
                                var ajaxManager = $find("<%= rapProjects.ClientID %>");
                                ajaxManager.ajaxRequest('');
                                return false;
                            }

                            function ProjectsResponseEnd(sender, eventArgs) {
                                var combo = $find("<%= rcbProjects.ClientID %>");
                                window.alert(combo); //HERE combo is null in Chrome, Opera, Safari
                            }
                       </script>

Hello Sergey,

I tested your code on the browsers you have specified but the client-side object of the RadComboBox is retrieved successfully. Can you confirm that the markup you have pasted is enough to reproduce the issue?

All the best,

  .T{ color:red;

</style>
