Hi!,
TargetFramework: 4.5.2
DLL from C:\Program Files (x86)\Progress\Telerik UI for ASP.NET AJAX R2 2020\Bin45
Starting first default page debugger in Visual Studio give me Exception Unhanded: DOMException: Failed to execute 'querySelectorAll' on 'Element': '*,:x' is not a valid selector. Visual stop just after comment below (Please check attachment).
/* END Telerik.Web.UI.Common.Core.js *//* START Telerik.Web.UI.Common.jQuery.js *//*! jQuery v1.12.4 | (c) jQuery Foundation | jquery.org/license */
Also loading pages is slow. Maybe because this exception occurs 2 times per each page (on loading).
Page is simple:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="q.aspx.cs" Inherits="Stocks.q" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Logowanie</title></head><body> <form id="form1" runat="server"> <telerik:RadScriptManager ID="rsm" runat="server"> <Scripts> <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /> <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" /> <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" /> </Scripts> </telerik:RadScriptManager> <script type="text/javascript"></script> <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> </telerik:RadAjaxManager> <asp:Table ID="Table1" runat="server" HorizontalAlign="Center"> <asp:TableRow runat="server"> <asp:TableCell runat="server" ColumnSpan="2" HorizontalAlign="Center"> <telerik:RadLabel ID="RadLabel1" runat="server" Text="test"></telerik:RadLabel> </asp:TableCell> </asp:TableRow> </asp:Table> </form></body></html>

Hi Dominik,
Are you, by any chance, using Unobtrusive Validation in your project? If so, can you disable it and see if the result will be the same?
<configuration>
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
</configuration>Would it be possible to send me the web config of the project in which the error is thrown so I can examine it further?
Regards,
Vessy

Hi Vessy,
Recently, I have the same issue when developing my new webforms app, and found this post. To simplify the situation, I created a new Telerik Webforms Application with default settings for testing. And I still got the same problem as below pic. Do you have any suggestions?
Telerik ajax version: 2022.1.119.45
.NET framework: 4.8
Best regards,
Alvin
Hi Alvin,
Did you try disabling the UnobtrusiveValidationMode like suggested in my previous reply?

Hi Rochelle,
You can find more reasons for the reported error in StackOverflow: JQuery error during load "Failed to execute query: '*,:x' is not a valid selector.".
If you are unable to resolve the problem, please isolate it in a simple runnable project and send it for examination via a support ticket. Please also include a screenshot of the error.
