Pasting plain text content from notepad or other text editor into the RadEditor control (design view) results in container HTML tags adding to the content and inline styles that make the text unreadable.

Content pasted:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut placerat orci nulla pellentesque dignissim enim sit. Diam quam nulla porttitor massa id neque. Ipsum suspendisse ultrices gravida dictum fusce ut. Sed odio morbi quis commodo odio aenean. Sed faucibus turpis in eu mi bibendum neque egestas congue. Sed pulvinar proin gravida hendrerit. Cras semper auctor neque vitae tempus. Nisi porta lorem mollis aliquam ut porttitor leo a diam. Quis vel eros donec ac odio tempor. Tellus in metus vulputate eu scelerisque felis imperdiet proin. Et ligula ullamcorper malesuada proin libero nunc consequat interdum. Neque viverra justo nec ultrices.

Result in RadEditor:

<div class="telerik_paste_container" style="border-width: 0px; position: absolute; overflow: hidden; margin: 0px; padding: 0px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut placerat orci nulla pellentesque dignissim enim sit. Diam quam nulla porttitor massa id neque. Ipsum suspendisse ultrices gravida dictum fusce ut. Sed odio morbi quis commodo odio aenean.

Hello,

I'm facing JavaScript issues after enabling "Telerik.ScriptManager.EnableHandlerEncryption" on Web.config,

I've just followed Encrypt Telerik WebResource Querystring in order to hide the Telerik version.

After this the RadMenu breaks when i do a PostBack action (by pressing a button), the console outputs the same error when hovering a RadMenuItem and the submenus has stop being displayed.

The console error:

Uncaught TypeError: Cannot read properties of null (reading 'apply')
  at Type.callBaseMethod (Telerik.Web.UI.WebRe...=:6:7353)
  at c.RadMenuItem._createChildControls (Telerik.Web.UI.WebRe...=:5300:49)

  at HTMLDivElement.<anonymous> (Telerik.Web.UI.WebRe...=:6:307)
  at HTMLDivElement.b (Telerik.Web.UI.WebRe...=:623:53)

I've tested this error with version 2020.2.617.45 and 2022.3.913 but the same problem.

Looking in the forum i've found this post with a related issue also a reply has a reference to a private feedback and this last one seems to be the same or almost the same problem, so i've tried to follow the workaround on "global.asax" file and "Page_Load" on the master page without luck.

The steps i've follow:

• Enabling "Telerik.ScriptManager.EnableHandlerEncryption".
• Site seems working correctly.
• I press a RadButton inside a RadAjaxPane.
• Response from server is OK.
• Then i hover the cursor on RadMenuItems on RadMenu.
• Console starts to show the related error explaining above.
• RadMenu stops to present the submenus completely.

I'd like to have another way to workaround this in order to make RadMenu work properly again and keep Telerik version hidden.

Regards
