Hi,
I am working on making application CSP complaint using UI for ASP.NET MVC R1 2023 SP2 (version 2023.1.425).
Grid column is having ClientTemplate which is causing grid to be empty. This was working prior.
Below is the code snippet:
.ClientTemplate("<a target='_blank' href=" + @Url.Action("ReportRouter", "Reports") + "?reportId=#=ReportId#>#=DisplayName#</a>");
Developer tool is showing Invalid template error. I have also added
@(Html.Kendo().DeferredScriptFile())
Any input is appreciated.

Hello Laxmi,
Thank you for the code snippet and details provided.
In order to achieve the desired result, I would recommend using a function handler.
From the function handler, use an Ajax Request to the "ReportRouter" Action Method and return the needed content.
Give a try to the approach above and let me know if is achieves the desired result.
Kind Regards,

As of R2 2023, the default icon type will be SVG instead of Font. See this blogpost for more information.

Hi,
Any update on this how to fix the above issue. I am also facing the same issue. ClientTemplate is not able to recognize when using @(Html.Kendo().DeferredScriptFile())
The issue comes from using a strict Content Security Policy (CSP) together with the Grid's ClientTemplate, which relies on inline templates. Strict CSP blocks inline JavaScript, causing templates to fail and the grid to appear empty. The use of @(Html.Kendo().DeferredScriptFile()) helps move scripts to external files, but it does not resolve issues with inline templates.
Solution: Use ClientTemplateHandler for CSP Compliance.
Instead of using .ClientTemplate(), use .ClientTemplateHandler(). This lets you define the template logic in an external JavaScript function, which is allowed by strict CSP.
I hope this information helps.
Best Regards,
