[Solved] Telerik Reporting Upgrade caused functionality to be removed.

[Jeremy]

Hello,

Inherited an older application that used version "16.2.22.914"

When I follow the upgrading wizard to go to "19.1.25.521" it removes the button to export reports:

Old view:

New view:

 

Not sure if the new versions needed some additional packages added to bring this functionality in.

 

But any help or advice would be extremely appreciated!

Hello Jeremy,

Thank you for the provided screenshots.

Between version 16.2.22.914 and 19.1.25.521, the HTML5 Report Viewer underwent significant changes. Most notably, the switch from Kendo UI Less-based themes to Kendo UI SASS-based themes. The Upgrade Wizard updates the server-side assemblies but may not fully update the client-side references (JS, CSS, template).

The viewer JS, CSS, Kendo UI subset, HTML template, and the REST Service must all be version 19.1.25.521.

The export dropdown is part of the HTML5 Report Viewer toolbar, and when it disappears after an upgrade, it is almost always caused by mismatched or outdated viewer client-side resources.

The HTML5 Report Viewer requires Kendo UI Sass-based themes instead of the older Less-based themes. Replace the old Kendo Less-based CSS:

<!-- OLD (remove this) -->
<link href="https://kendo.cdn.telerik.com/2022.x.xxx/styles/kendo.common.min.css" rel="stylesheet" />
<link href="https://kendo.cdn.telerik.com/2022.x.xxx/styles/kendo.default.min.css" rel="stylesheet" />

With the new Kendo SASS theme:

<!-- NEW -->
<link href="https://kendo.cdn.telerik.com/themes/12.3.0/default/default-ocean-blue.css" rel="stylesheet" />

Version 19.1.25.521 requires jQuery 3.7.1 or newer. If your application is currently using an older version, I recommend upgrading the jQuery dependency. For example:

<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>

Also, you can clear your browser cache (Ctrl+Shift+R) to ensure no old JS/CSS files are being served from cache.
