Datagridview how to discard a selected row in a custom object

Question

I am using C # winforms with an MSSQL database. I have a table in the Pilots database, I populate the datagridview "dgvPilots", with data from the Pilots table.

dgvPilots.DataSource = Connection.dm.Pilots.ToList();

I turn on multiselect. now i need to get multitask data from datagridview. How can I display multisecond strings for a Pilots object and get PilotsID.

My current error is: "Cannot use DataGridViewRow object type to enter" .Data.Pilots "...

I am also trying to do it like

dgvPilots.SelectedRows.Cast<Pilots>().ToList();

but it returns the type of the DataGridViewRow element.

Answer 1

DataBoundItem, .

var pilots = new List<Pilots>(grid.SelectedRows.Count);

for(int index = 0; index < grid.SelectedRows.Count; index++)
{
   var selectedRow = grid.SelectedRows[index];
   var pilot = (Pilots)selectedRow.DataBoundItem;

   pilots.Add(pilot);
}

First, wait three years for your answer.

Secondly, please do not repeat.

var selectedPilots = 
            (from DataGridViewRow cada in dgvPilots.SelectedRows select cada.DataBoundItem)
            .Select(x => (Pilots)x).ToList();
