I'm looking for a way to show the sum of a column on the group line like in this example : https://docs.telerik.com/kendo-ui/knowledge-base/grid-align-group-header-with-cells, but for every group possible. In others words, I would like to show, let's say the total of Completed tasks no matter the grouping so if I group by age, the total of Completed tasks will be shown on the group header. If I group by age, the total of Completed tasks would be shown on the group header as well.
By enabling the grouping in the Grid, it seems that this only works for the group specified in the data source.
Please see my example : https://dojo.telerik.com/OcuquWOd
As you can see, the Count is only shown when the grid is grouped by Units in stocks. When the group is on another column, the Count is no more shown.
Do you have any idea on how to achieve this ?
