Is it possible to have sections within sections (sub sections) in the DataGrid?
Is it possible to have section footers in the DataGrid? I need to have a totals row in each section.
Not out of box for either (still) as far as I know.
For sub-sections, here is a post that has a working prototype drill down grid which you could probably modify for subsections. Only thing is it's in Objective-C but shouldn't be hard to convert to Xamarin: https://www.shinobicontrols.com/forum/shinobicontrols/2015/1/drill-down-table-in-shinobidata-grid
For footers, here is a post with some insight into them: https://www.shinobicontrols.com/forum/shinobicontrols/2014/2/datagrid-is-there-a-way-to-have-a-frozen-footer
