Hi
I have a grid where a field is a List<MyObject>.
In the razor page I used a template where I convert the cities collection (for example) separated by a comma, into a single string. The grid work correctly and in the cell grid I see the city list.
When export to excel I implemented ExcelQueryCellInfoHandler and assigned to args.cell.Value the same conversion but in the exported excel file I see
System.Collections.Generic.List`1[MyObject] in the cell value.
where am I wrong?
thanks in advance
