I am doing a POC to demo the Kendo UI ASP.NET Core components for our application. I would like to know how to apply the themes (such as Blue Opal, Bootstrap, Fiori, Flat, High Contrast, Material, Metro, Moonlight, Nova etc.,) that are shown on the top of Telerik demo pages. Please see the attached snapshot for reference. When we select any theme on the list, the Grid control will change the display accordingly. However, I do not find the code to apply the themes. Please provide the sample or link where I could find the code. Thanks in advance.
