Good morning

Was there issues with any recent updated to Telerik?  I have just noticed that in Design View of my visual studio project, none of my Telerik RadGrds are displayed anymore.  Instead I get a control box on each grid with the error "Sysem.NullReferenceException"

Hi, I recently received a new laptop at work.  I was eventually able to compile and run both of my 2 applications in localhost, and deploy one of them to Dev and Prod.  However, I am having problems deploying my 2nd application. 

Again, it works fine in localhost.  When I deploy to the Dev environment, I get the error:

Could not load file or assembly 'Telerik.Web.UI, Version=2018.1.117.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The version my reference points to is 2018.2.516.45.  So I don't know where the 2018.1.117.45 version is coming from, or why it is attempting to load this version.

Yes, I KNOW that this is an old version. If need be, I can probably upgrade to a newer version.  But if I can't figure out the version mis-match now, I think I will have the same problem with a newer version.  

Any help is appreciated.  

Thanks!

I'm using a Telerik RadGrid with nested grids (using NestedViewTemplate) inside an ASP.NET Web Forms page. I've enabled scrolling with AllowScroll="true" and UseStaticHeaders="true", and set a fixed width for the outer container with horizontal scrolling.

The issue is that when I scroll horizontally to the right and then expand a nested row, the inner RadGrid (in the nested view) does not align properly or its scroll resets to the left. I want both the parent and child grids to stay aligned and scroll consistently, especially when expanding/collapsing rows.

Has anyone faced a similar issue or found a good way to synchronize scrolling between parent and nested grids?

I have web projects that I am trying to update with the new 2025 Q1 assemblies and am getting a build error of the TelerikLicense.vb file.

I followed these instructions:

1. Search for AJAX.
2. Click on View key next to the Progress® Telerik® UI for ASP.NET AJAX.
3. Copy the Script Key.
4. Add a file to your project, e.g. TelerikLicense.cs (for VB projects add TelerikLicense.vb).
   • In case of ASP Web Site solution, add the file to the App_Code folder.
5. Paste the Script Key into the file.
6. Build the project.

TelerikLicense.vb error BC30034: Bracketed identifier is missing closing ']'.

ScriptResource.axd?d=pbopGUyRoGMceL-ci2EaNCr6Dz-J2c03WyoCKxBcDTMoBx3qAj23lItrM0pL-o5km9ikY4QfqRDuZH3-53hC0jR2CXHTAiQgYV-9MhRb5Jp16E4Zndorh_IoOL8UoIu8Pe13tmi_DG4t62kaEGe6RDQrD0-3W0mu3F-NX0n8K3Q1&t=4227dd99:4233 Uncaught Sys.ArgumentUndefinedException: Sys.ArgumentUndefinedException:

I have created an application within Visual Studio 2019 and using c#.

The project has a page which uses a telerik RadGrid. It is populated on page load and I have filtering enabled on 3 of the columns. I have set the aspx for the columns to have AutoPostBackOnFilter="true" AllowFiltering="true"  ShowFilterIcon="true"

The runs perfectly when ran in development environment but when I publish my application to the web server the filter does not work at all. Nothing happens if I tab out of the filter text box or if I select anything from the filter icon.

Can anyone advise what the issue could be please? I am using Telerik.web.ui version 2024.1.131.45

Thanks

If I have a subscription license that’s active and publish an application to a production environment, all is well.

Scenario case, if my license expires, and I make an update to the application, same version of Telerik controls, but now with an expired license. 
If I publish a new version of the application, will it still function without the license key messages? 

From what I understand, it will still function and no license messages assuming I don't update the Telerik Controls.

I have a radgrid with a standard modal popup for making entries.  Everything works as it should.  However, I have been trying to modify the field in the popup window so the user would see a multiline box to make entries. 

I've tried css, asp:textbox,  and other ideas. but they all failed.  Here is my code..... 

any help would be appriciated.
