I need to calculate a grouping value by myself as the standard GridAggregateTypes are not suitable in my case (I need to calculate a percentage based on the aggregated values of other columns in the same grouping).
This is possible for the GridFooterTemplate as the GridGroupTemplateContext provides the AggregateResults from which I can calculate the value to be shown.
However, the GridGroupTemplateContext provided by the GroupFooterTemplate does not provide such a property.
Any kind of solution is helpful, even if it is a dirty workaround.
Thank you very much and best regards - Richard
