hello all,
i want to export data from excel sheet to database but first i want to filter the data so i want to store that data in List to do some edit then pass it to the table

i use SQl server and Entity framework
i fill the excel sheet on data grid, then i tried to import the data from the data grid to the list but the data grid has no static column header name, because the excel may have many columns i will pick what i need.

the data is shown in the datagrid.

my list of object is :
List<devicet> Li = new List<devicet>();
and the table DeviceT has 8 rows and the imported excel sheet has just 5.
i want to fill the correct column in the correct place on a list

What I have tried:

i export the data to datagrid, i cannot export data from datagrid to list

If you were to search CodeProject for solution, you would find this article (among others):

CSV/Excel File Parser - A Revisit[^]

If column names aren't included in the data, the code cited above adds column names in the format 'Column N', where 'N' is the ordinal position of the column.

If you're doing WPF correctly, the datagrid should already be bound to a collection, and should be accessible via the ItemsSource property.

actually, i use
datagrid.itemssource=EFM.Tablename.tolist();
i cannot bind it back to list using itemsource

Is your collection an ObservableCollection?
