Answer 1

Suppose in your Table you have a column named id and you want to delete from database based on id. Try this:

private void btnDelete_Click(object sender, EventArgs e)
{
    foreach (DataGridViewRow item in dataGridView1.SelectedRows)
    {
       var id = item.Cells[0].Value.ToString();//You can change id and Cells[0] as your need
       //Write Delete code like this (Delete from Table where id = @id)
       dataGridView1.Rows.RemoveAt(item.Index);//Remove from dataGridView1
    }
}
