Hello Neil and Joe,
Typically, using AJAX to load up Kendo Widgets should commonly be accomplished by making sure that the widgets are being resized using the resize method.
When to use the resize method and in which scenario greatly depends on the layout of the application the DOM elements you are using in that layout.
Kendo widgets can get their wrapper elements' sizes and be able to redraw themselves properly. But with by rendering them using AJAX, there is no proper trigger that can possible be handled programmatically to properly render the widgets as per to the exact size of the layout.
