i have made a datatable with the list and the datagridview doesn´t show anything. i donßt know what happends , but i have a problem with the datagridview

Hi !
Sory I cannot see any code where you are really binding the grid to your list, When do you call the method 'seedatagrid' and where the list is filled.
So basially the code you are showig is too less to see what you are doing
