In version 2025 Q2, I am getting the following error message when opening the RadGrid in design mode: 

System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.Web.UI.Licensing.TelerikLicense.get_CurrentHost() at Telerik.Web.UI.Licensing.TelerikLicense.get_IsLicenseValid() at Telerik.Web.UI.RadGrid.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Design.ControlDesigner.GetDesignTimeHtml()

Form controls rendered by the embedded columns (GridBoundColumn, GridDateTimeColumn, GridNumericColumn, etc.) in EditMode="Batch" do not have a label set and fail the accessibility checks.

The issue occurs when setting the Enabled property to false, which triggers a JavaScript error and causes the components to break.

Code to replicate the problem

<telerik:RadTextBox ID="RadTextBox1" runat="server" Enabled="false"></telerik:RadTextBox>

Hi 

I have a RadEditor control where some toolbar functionalities are not working.

After searching for a possible reason, I used the OnClientCommandExecuting client-side event and noticed that sometimes, instead of the args with its value, I found the item of a RadTreeList control present on the page.

I tried to reproduce the issue by inserting an Editor and a TreeList on a page. I write some text in the Editor and try to change the color or background. Not always (and I can't figure out when), but sometimes the args are incorrect.

For example, if I open a node of the tree, the error is almost certain after that.

I send you an image of my javascript debugger.

I don't know what I can do, do you have any ideas?

Thanks

Michela

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Yes, ASP.NET Webforms is outdated, but it's still around, and I think many developers are looking at moving to a newer and more modern technology.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!

Dear Support Team,

we are currently trying out RadPdfViewer and have found that hyperlinks in the PDFs do not work.

During my research, I found that this has now been implemented for the Kendo UI PDF viewer for Angular (https://www.telerik.com/kendo-angular-ui/components/changelogs/kendo-angular-ui#v18.5.0).
Will this also be implemented for the ASP.NET viewer, and if so, when?

Best regards

Frank

When on an Android mobile device, dragging the Splitter SplitBar moves a small part of the Splitter and the page itself. The issue can be observed on the Splitter Demo when accessed from a phone.

Hi Team,

I would like to request a way to insert a new record at the bottom of the InPlace Editable RadGrid so that the row would be within the RadGrid container.

Thank you!

Hi, 

I am using the pdf viewer control and can't find anything on displaying the PDF document in a 2 page spread mode e.g. page 1 and 2 side by side, 3 and 4 side by side etc.

Does the control support this?

 

Thanks

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

The bottom part of the last page of the PDF document stays hidden. If dragged with the mouse, the Page will move and can be viewed, releasing the mouse will scroll it back as a result, hiding the bottom part.

Issue can also be observed with the following demo: https://demos.telerik.com/aspnet-ajax/pdfviewer/overview/defaultcs.aspx

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!
