http://demos.telerik.com/kendo-ui/pivotgrid/index I think it would be great addition to add the ability to set KPI's for the grid & pivot grids in Kendo UI. We have used this on you ajaz & mvc controls but are now migrating to a pure html5/kendo ui based website. Please consider this as a feature for your the proposed controls.
PivotGrid KPIs support is shipped in Q3 2014
