I would like to see OTP Input available in the ASP.NET Ajax how in the ASP.NET MVC: https://demos.telerik.com/aspnet-mvc/otpinput

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.

Yes, ASP.NET Webforms is outdated, but it's still around, and I think many developers are looking at moving to a newer and more modern technology. But in some cases - including mine - it's not really possible to refactor an application that has grown for 20 years overnight. The only thing I can do is put a lot of energy into changing the CSS of the controls. Which is not always easy.

I really appreciate the functionality of the Telerik controls and think it's a shame that they don't get a visual and functional update.

In this specific case, it is about the Datepicker Control, which has a different behavior than the more modern version under .NET Core. For example, the month or year selection opens in a new DIV popup. In the more modern control, this is solved in a more elegant and modern way.

I think that this list of controls that need a “front-end pimp” can certainly be extended.

Thank you!

Hi,

    many customers are asking us a more MS Word-like editor supporting true document layout features such as:

• page margins and rulers
• Headers and footers
• section breaks or document structure more similar to MS Word
• Microsoft Word-inspired UI

Many thanks,

Max

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!

Based on Ticket ID 1683806  it was suggested to add this here.  It should be fairly straight forward and would resolve issues that I have.

My Suggestion:

Why can you not just add the clientEvents to the RadEditor1.FileExplorerSettings

Something like RadEditor1.FileExplorerSettings.ClientEvents.OnClientFileOpen="somefunction"

 

Your response.

Thank you for your suggestion to add client events directly to RadEditor1.FileExplorerSettings. It's a thoughtful idea that could indeed enhance client-side flexibility and streamline interactions.

At present, this feature is not available. However, we encourage you to submit it as a feature request through our public feedback portal, where our product team actively reviews community input for potential inclusion in future updates.

 

Also, please see my ticket for a bug in the ImageManager using th URL to return the item instead of the OriginalPath.  This makes my custom content provider not feasible.

 

 

Thanks!

Please create a Bootstrap 5 skin so we can use Bootstrap 5 along with Ajax components on the same page and colors/spacings and everything else would look the same. Current Bootstrap 3 skin is limiting to use Bootstrap 3 on other page elements

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. 

I know its a long shot, but do you have anything that resembles the attached control.

Thank you

 

Upgrading Telerik UI for ASP.NET AJAX to version 2025 Q1 (2025.1.211) throw a JavaScript error:

• Uncaught TypeError: Cannot read properties of undefined (reading 'parentElement')

Steps to reproduce: Have a RadWindow with NavigateUrl set to a different page:

<telerik:RadWindow ID="RadWindow1" runat="server" RenderMode="Classic" VisibleOnPageLoad="true" NavigateUrl="Default.aspx">
</telerik:RadWindow>

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.

Before 2025 Q1

In 2025 Q1

 

Hi,

Would it possible to build in a text search filter into a Listbox?

Currently, the TreeView is expecting touch events (touchstart, touchmove, touchend) to be triggered by touch devices,  while the Magic keyboard sends mouse events.

I reeally would like to see the Blazor Sankey Chart component in the ASP.NET AJAX library!

Kind regards

Replace the obsolete Import method overload in RadEditor source code. These method now use the updated overload that include a TimeSpan? timeout parameter. Add a new timeout setting SecurityHelper.ImportTimeout to ensure configurable timeout handling across the application. The update aligns with modern practices for enhanced application performance and reliability.

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 ...

This request was necessary because ticket 1665797 don't solved.

There is a formatting issue in the editor when the "Tab" key is pressed, triggering the editor's "InsertTab" event on text that has been modified by another user. In this event, when set_enableTrackChangesOverride(true) is enabled, the editor inserts an "a" character and misformats the text in question (as shown in the video). When set_enableTrackChangesOverride(false) is set, this error does not occur.

Note: In this scenario, we need track changes enabled so the user can accept or reject the changes made by the previous user, and set_enableTrackChangesOverride(true) so that the current user can reconcile the changes made by both User 1 and User 2 without tracking their own modifications.

Before insert Tab:


After insert Tab:
