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. 

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 ( ) appear in the list items. This causes unexpected indentation and formatting issues.

Before 2025 Q1

In 2025 Q1

 

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

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 ...

TEST ENVIRONMENT

OS: Windows_11

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. 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.</div>

See accompanying screenshots.

Please consider to add a demo scenario when MultiColumnComboBox is used as RadGrid column filter

When the grid has a horizontal scroll bar displayed, we can't scroll the table horizontally using keyboard only.  If testing using the Siteimprove Accessibility Checker, we will get the issue "Scrollable element is not keyboard accessible".

The reason is that when the RadGrid is rendered, the horizontal scroll bar is render as a separate <div> out of the data table, and the horizontal scroll bar doesn’t have a tabindex, so there’s no way to put focus on it using keyboard.  Can you add tabindex="0" to the horizontal scroll bar?

 

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.

Hi,
I am using ASP.NET AJAX Q1 2011 SP2. My IT department has notified me that there is a security vulnerability with Telerik UI for ASP.NET AJAX RadAsyncUpload . NET Deserialization Vulnerability. Please advise how this issue can be resolved.

Telerik document shows upgraded Rad components support WCAG 2.0,  section 508, not sure any plan or target date to upgrade Rad components support WCAG 2.1?

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.

Hi Telerik,

Just a heads-up - some of the demo pages are generating errors:

Server Error in '/aspnet-ajax' Application.

---

Runtime Error

Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.

 

I have found this on:

https://demos.telerik.com/aspnet-ajax/errorpageresources.aspx?aspxerrorpath=/aspnet-ajax/grid/examples/overview/defaultcs.aspx

https://demos.telerik.com/aspnet-ajax/errorpageresources.aspx?aspxerrorpath=/aspnet-ajax/htmlchart/examples/overview/defaultcs.aspx

 

The issue can be replicated with AutoCompleteBox demo: https://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

Set the SingleLineEntries property to "Enabled", and add a new Entry to the AutoCompleteBox. At this point, the page will scroll up and as a result hiding the AutoCompleteBox.
