Hi,

We have old version of Telerik reporting . and old version of Kendo UI library(on our client side)

we use with Rest API in server side and with HTML5 Telerik report viewer in client side. 

Now we want to upgrade our Telerik reporting version.

The behaviour of the new HTML5 report viewer depends on a new version of the Kendo ui.

We have a big project and we do not want to upgrade Kendo Ui library.

Is it possible to upgrade only the server side of the reports?
Without upgrading Reporter Viewer?

 

Thanks,

Chani

Hello Chani,

Generally, all the Telerik Reporting resources that interact should be with the same version. This includes the viewer's JavaScript and styles that rely on certain Kendo versions. Unfortunately, an upgraded Reporting service will not work as expected with an older Html5 Viewer and you need to upgrade them both.

I confirm also that we now rely on Telerik Kendo UI (2020.3.1118 or later) - see R1 2022. If you use an older Kendo version, the style and the functionality of the viewer may be broken.

As a workaround, you may consider upgrading the Kendo suite only on the page with the viewer.
