Dear Telerik Support.  I found another bug related to this one below.

https://feedback.telerik.com/aspnet-ajax/1688270-uncaught-typeerror-cannot-read-properties-of-null-reading-classname?_gl=1*iuxa0l*_gcl_au*NjcwNTkzNi4xNzQ3Njc4MzQz*_ga*OTAxNzk1OTc4LjE3Mzk4MjI5NzY.*_ga_9JSNBCSF54*czE3NDgwOTkxODEkbzIxJGcxJHQxNzQ4MDk5NTIzJGo1NCRsMCRoMCRkRlJROUp0Q0RDUUZTUlZUeFlLLU9ja3RBc2UwczF3ZU55Zw..

This line of code also causes the same issue.

$find("txtYear").clear();

See attached Console debug output.

It is my opinion that a hot fix needs to be done asap!  The work around that Derek posted on May 23rd falls short of the bigger issue.  This is a serious matter and needs to be addressed immediately.

Hello -

I just updated my components to 2025.1.218, and am receiving the following ADA Compliance issues on a page scan.  This is to conform to WCAG 2.1 AA.  The component is the Ajax telerik:RadComboBox:

Buttons must have discernible text

<button class="rcbActionButton" tabindex="-1" type="button">select</button>

Form elements must have labels

<input name="ctl00$MainContent$ComboBox$NewCombo" type="text" class="rcbInput radPreventDecorate rcbEmptyMessage" id="ctl00_MainContent_ComboBox_NewCombo_Input" value="Search..." autocomplete="off"></input>

Component in .ascx file:

<telerik:RadComboBox ID="ComboBox" runat="server" RenderMode="Lightweight"
    EmptyMessage="Search..."
    AllowCustomText="true"
    MarkFirstMatch="true"
    Skin="Bootstrap"
    AutoPostBack="true"
    SelectMethod="GetInfo"
    DataValueField="Id"
    DataTextField="Name"
    OnSelectedIndexChanged="ComboBox_SelectedIndexChanged"
    MaxHeight="250px" aria-labelledby="InfoLabel" />

Please advise.  Thanks!

In RadEditor when specifying WordIgnoreOptions="None", I would expect that "THe" would be flagged as a misspelling, but it is not. It appears the WordIgnoreOptions is being ignored.

When pasting bullet lists from Microsoft Word into the editor, extra leading spaces (&nbsp;) appear in the list items. This causes unexpected indentation and formatting issues.

Update the Render methods in XlsxRenderer.cs and DocxRenderer.cs to replace obsolete Export method overloads from IWorkbookFormatProvider and DocxFormatProvider. These methods now use the updated overloads that include a TimeSpan? timeout parameter. Add a new timeout setting SecurityHelper.ExportTimeout to ensure configurable timeout handling across the application. The update resolves compiler warnings (CS0618) caused by the usage of deprecated method overloads and aligns with modern practices for enhanced application performance and reliability.

Hello

I have an ASP.NET Ajax Telerik Solution (site) that has a web site project and a library project.  The solution was developed almost 8 years ago and so far I've been able to upgrade telerik controls  several times without any problem. Now, when I tried to upgrade the Telerik controls using the Upgrade Wizard Project only shows the class library as you can see in the attached picture.

To replicate this beahavior:

1. Create a new Telerik VB Webform Site
2. Add a Class Library Net Framework project to the solution.
3. Add a reference to Telerik.Web.UI to the Class Library project (optional).
4. Save and close solution.
5. Reopen it and run the Telerik Upgrade Wizard Project.

It only shows the Class Library project ...

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 c.RadMenuItem._ensureChildControls (Telerik.Web.UI.WebRe...=:2770:72)
  at c.RadMenuItem._getChildren (Telerik.Web.UI.WebRe...=:2768:32)

  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

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.

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:

When frozen column is used in the Grid, when user moves the cursor onto an out-of-the-screen element in the table header, the screen will not scroll automatically to make the element shown. When frozen column is not used, there's no such issue. This should be a bug of the RadGrid control.

Hello,

Sometimes the context menu isn't positioned correctly when it pops up for the first time, or after you scroll the page or do a browser zoom. I've attached an example reported by our tester. I've checked your technical support and have found this:

https://feedback.telerik.com/aspnet-ajax/1374622-context-menus-mispositioned-after-page-scroll-when-contentareamode-div?_ga=2.47056743.1148387732.1712639084-795296971.1689564005&_gl=1*1fbejbs*_ga*Nzk1Mjk2OTcxLjE2ODk1NjQwMDU.*_ga_9JSNBCSF54*MTcxMjcwNTQxNS42NS4xLjE3MTI3MDY1NTUuNjAuMC4w*_gcl_au*MTk5NTg1MzE3OS4xNzEyMjAwMDcy

I've tried setting the render mode to Lightweight (originally set to Auto), but unfortunately no luck.

Is this something that is fixed in a later version of the editor, or do you have another fix/workaround?

Thank you in advance,

Gerald

When assigning multiple resources and percentages, the first item in list always goes back to 100%.

It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.

The online demo has the same code but demo doesn't save at all to test.

See attached screen shots.

The behavior can be replicated in the Circular Gauge live demo by showing/hiding scale labels. Use the ScaleLabels Visible checkbox in the demo configurator.
