[Paulo]

I dont know how to get the ID if the RadGrid is dynamically 

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnablePartialRendering="true"
    LoadScriptsBeforeUI="false" EnableCdn="true"   ScriptMode="Release">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="RadInputManager1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="RadWindowManager1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

  <asp:Repeater ID="rp1" runat="server" OnItemDataBound="rp1_ItemDataBound">

Hello,

Please try to wrap the Repeater into single asp Panel and add this Panel into the RadAjaxManager settings to update itself. Also set ClientIDMode="AutoID" for your Repeater. The Manager can only handler AutoID, because it uses the server side ClientID property of the control, to Ajaxify it later client side.
