Hello Ivan,

Please try to change your code as shown bellow and see if it works as expected:
ASPX:

    
             <asp:ScriptManager ID="ScriptManager" runat="server">  
        
                    </asp:ScriptManager> 
        
                    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                        <AjaxSettings> 
        
                            <telerik:AjaxSetting AjaxControlID="b1">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="p1" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                            <telerik:AjaxSetting AjaxControlID="b2">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="p2" /> 
        
                                    <telerik:AjaxUpdatedControl ControlID="p3" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
                    </telerik:RadAjaxManager> 
        
                    <asp:Panel ID="p1" runat="server">  
        
                        <%= DateTime.Now.ToString() %> 
        
                        <asp:Button ID="b1" runat="server" Text="b1" /> 
        
                    </asp:Panel> 
        
                    <asp:Panel ID="p2" runat="server">  
        
                        <%= DateTime.Now.ToString() %> 
        
                        <asp:Button ID="b2" runat="server" Text="b2" /> 
        
                    </asp:Panel> 
        
                    <asp:Panel ID="p3" runat="server">  
        
                        <%= DateTime.Now.ToString() %>
