Hello,
When I run my project that contains a RadGrid locally on my development machine using IIS Express, the grid is formatted as expected. When I publish to my web server (running Windows Server 2012 R2 / IIS 8.5), the grid loses all formatting and looks like a handful of plain HTML controls scattered on the page. I would guess this is something CSS-related, but I don't know where to look. In both cases, I'm opening the web site from Chrome on my development machine.
See attached "IISExpress.png" and "Publish.png" for visual examples.
I'm using Telerik UI for ASP.NET AJAX R1 2020. Telerik.Web.Design, Telerik.Web.UI, and Telerik.Web.UI.Skins DLL files are all copied local to the web server in the bin folder.
