Hello all,
I’m working on an inline editable Kendo Grid and trying to add a dropdown list for one of the columns. However, when I run it, the dropdown doesn’t load properly. Instead of showing the item names, the textbox displays [object Object].
I’m using Kendo version 2025.3.825, and my code must comply with CSP rules.
Could someone guide me on how to fix this so the dropdown shows the correct text values instead of the object?

Hi,
To implement CSP-compatible templates in the Telerik UI for ASP.NET MVC Grid, use the Template HtmlHelper or the Template component, which allow you to define templates without inline scripts or eval, ensuring strict Content Security Policy (CSP) compliance. Starting with version 2025 Q1, all templates enforce strict CSP mode, so migrating from legacy inline or script-based templates to the new Template approach is recommended for security and compatibility.
The recommended approach is to use the Template HtmlHelper to embed HTML and Telerik UI components directly in your Grid templates.
Check out the resources below that describe how to use the Template HtmlHelper with the Grid and additional information on CSP
