        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rgdUsrManager">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgdUsrManager" />

                </UpdatedControls>
            </telerik:AjaxSetting>

//when ever i selected the group in telerik:RadComboBox i fired an CmbUGrp_SelectedIndexChanged event like below

XML

<telerik:RadComboBox runat="server" ID="CmbUGrp"  Width="150px" Skin="Windows7"
                               DropDownWidth="200px" Height="200px" AutoPostBack="true"  CausesValidation="false"
                              SelectedValue='<%# Eval("GroupID") %>'   DataSourceID="DS_Groups"   DataTextField="GroupName" DataValueField="GroupID"
                                        AppendDataBoundItems="true"  OnSelectedIndexChanged="CmbUGrp_SelectedIndexChanged">

//so my problem was the grid is in update panel so thats why when ever the CmbUGrp_SelectedIndexChanged event fired it is not showing the loading symbol...so i need to put ajax loader while that event fired is it possible.....
