    Can the following article help?

    ASP.NET 4.5 ScriptManager Improvements in WebForms
    https://devblogs.microsoft.com/dotnet/asp-net-4-5-scriptmanager-improvements-in-webforms/

    In ASP.NET 4.5 or later version, for the server controls which use client script to work properly, the required scripts need to be registered to the ScriptManager and the pages should include the ScriptManger.

    See the following article if you use the Ajax Control Toolkit.

    Hi @juan maximiliano aguilar abanto ,
    You could try to do this:
    replace: 

      <add verb="GET" path="ScriptResource.axd" type="Microsoft.Web.Handlers.ScriptResourceHandler" validate="false"/>

    to: 

    <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False"/>

    Best regards,
