Answer 2

if you want to work with the same data in different forms, it is better that they exist somewhere separately, perhaps as a field in the main form, with the type:
- an array for a simple case, further on the complication of the task
- a data table https:/ /docs.microsoft.com/ru-ru/dotnet/api/system...
- database https://docs.microsoft.com/ru-ru/ef/
and do binding in grids. then all instances of the datagridview will work with the same source, and even display changes made in another grid
