Hello Felice,

Thank you for contacting us.

I noticed that you are nested RadAjaxManager inside RadAjaxPanel. Note that ajaxifing a single control by RadAjaxManager and RadAjaxPanel simultaneously is not supported scenario and you have to use one of the them. I would recommend you to remove the RadAjaxPanel and leave only the RadAjaxManager. Check out the following code snippet.
<table width="100%">
            <tr>
                <td>
                        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientEvents-OnRequestStart="conditionalPostback" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
                            <AjaxSettings>
                                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                                    <UpdatedControls>
                                        <telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>
                                    </UpdatedControls>
                                </telerik:AjaxSetting>
                            </AjaxSettings>
                        </telerik:RadAjaxManager>
                        <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Telerik">
                        </telerik:RadAjaxLoadingPanel>
.......

Additionally I would recommend you to review the following help articles which elaborates more on this matter.
RadAjaxPanel
RadAjaxManager

I hope this information proves helpful.
