Hi,

 I want to do subtraction between rows of a same group in the kendo grid (see attachment). I understand that aggregates doesn't support subtraction, and I'm encouraged to call functions from the groupFooterTemplate. However, I'm find it difficult to track which group I'm calculating the value for. What's the recommended way?

I'm not sure if there's a better solution to this. I dealt with it by calculating the differences myself and insert them as rows into my data. Then in the template, style that row differently (I put a attribute to identify itself).

Hello Ama,

Indeed, this behavior is not supported out of the box and can only be achieved using a custom implementation. The approach you described is more or less what we would have suggested as well.
