Is there a way to do custom grid summary using selected rows?

So for example as a user selects rows on the grid, we would like to display a footer with a running total of the selection. But I read in the documentation that Kendo UI does not support custom group and table summary aggregation logic. So is there a way around that?

 

Thanks

Hello David,

Indeed, the desired functionality is not supported, but can be achieved with some custom logic implementation.

A possible approach is to handle the Grid's dataBound event to append a custom row to the tbody, and then use the change event to adjust this row content based on the selected items (available via the select() method).

I have prepared a simple example, demonstrating the described approach:
