Report Viewer Parameters do not highlight after selection

[David]

I just upgraded to version 2023 R1 (with much difficulty with versions of Newtonsoft.Json).  When I run a report that has a parameter to pick from a list of choices the selected choice does not remain highlighted. I am using the MVC report viewer. It worked in the previous installed version 2202 r2 (16.1.22.511).

When I tried to add a new MVC report viewer it refuses to create a new one because all of the Telerik report viewers are 2022 R2. It refuses because the targeted version does not match the installed version. I ran the Upgrade Wizard again with no change, it still has 2022 R2 items in the list (see picture)

• Error: Incorrect version. The target project is using different Telerik Reporting version. Before adding this template the project should be upgraded with the Upgrade Wizard or you should choose item template for the correct Telerik Reporting version.

Then I removed all of the Telerik references, added the 2023 R1 references back in. Shut down Visual Studio and restarted. Try again to add a report viewer and it still says all of them are 2022 R2: Telerik Reporting, Telerik Reporting.OpenXmlRendering, Telerik Reporting.OpenXmlRendering.2.7.2, Telerik Reporting.Services.WebApi, and Telerik Reporting.Mvc.

This may be two problems instead of the one I thought I had.

Hello David,

Thank you for the provided information!

The issue with the selection is due to an upgrade to the minimum supported version of Kendo for our viewers and designer. From the Telerik Reporting - Progress® Telerik® Reporting R3 2022 SP1 (16.2.22.1109) release onward, we support Kendo UI 2022.3.931 or newer. If you do not use kendo in any other places in your application, the report viewer would automatically load the new kendo because we ship its subset with the other resources, however, if you load kendo someplace in your application before loading the report viewer, the viewer will use that kendo. This is the most likely scenario for the problem that you are experiencing and to resolve that, you just need to upgrade your kendo references.

For more details on the dependencies of the viewers, you may have a look at the R1 2023 Release Overview - Telerik Reporting article.

Regarding the second issue, with the item templates and overall Visual Studio integration of the Telerik Reporting product, for that to happen, I assume that you have only updated the package/assembly references in the project to R1 2023 but have not installed the new version via the .MSI. The Telerik Reporting extension is actually added during the installation so if you have not run the installer, please do so after closing all instances of Visual Studio. If the installer was run but the templates are still with the new version, then it must have encountered some kind of a problem during the installation and now you may try to manually re-install only the extension. To do that, you may go to the following location:

C:\Program Files (x86)\Progress\Telerik Reporting R1 2023\Bin\VS[Year]

And double click the .VSIX file to start the installation of the extension.

I hope that the provided information will help, please do not hesitate to let me know if you need further assistance.
