DataGridView AllowUserToAddRow property doesn't work

Question

I have a simple project with Entity Framework, I have a DataGridView in my Form and I set its AllowUserToAddRow property to true

Answer 1

I have just painfully upgraded to EF 6 from 4 and I have a similar issue, the solution in EF6 is below and I have shown a where statement for further help.

DBEntities context = new DBEntities();
private void Form1_Load(object sender, EventArgs e)
{
  context.MyTable.Where(e => e.myField == 1).Load();

  BindingSource bs = new BindingSource();
  bs.DataSource = context.MyTable.Local.ToBindingList();
  myDatagridView.DataSource = bs;
}

You can now use context.SaveChanges(); to save the changes or inserts
