The refresh button availability should be indepent from the grid being pageable. The user may want an updatable grid without having page navigator.
Done - http://demos.telerik.com/kendo-ui/grid/toolbar-template
Looks like this is already done. .Pageable(pager => pager.Info(false).Numeric(false).PageSizes(false).PreviousNext(false).Refresh(true))
Should be a command for a refresh button that can be added to the toolbar commands WITHOUT requiring the grid to be pageable.
