DataGridView - when using Fill / Append Methods don´t allow AllowUserToAddRows

Hi.

I have a grid that loads data from a List trough Fill or Append methods.

This grid don´t needs to be bound, as receives the data from an API.

I´m working on the premisse that the the fill/append methods is only a fast way to load data, then disconnect from the source.

1 – When using this code, the AllowUserToAddRows functionality DON’T work after the data load.

————————————————————————————————-

var lista = await vwGroups.GetGroups(account, status);

var bs = new BindingSource(lista, null);

dg1.Columns[1].DataPropertyName = “name”;
dg1.Columns[2].DataPropertyName = “description”;
dg1.Columns[3].DataPropertyName = “status”;
dg1.Columns[4].DataPropertyName = “groupGUID”;

dg1.Fill(lista);

2 – When load data using foreach works, as expected.

List<Groups> g = new List<Groups>();

var listGroups = await vwGroups.GetGroups(conta, status);

//var bs = new BindingSource(lista, null);

//dg1.Columns[1].DataPropertyName = “name”;
//dg1.Columns[2].DataPropertyName = “description”;
//dg1.Columns[3].DataPropertyName = “status”;
//dg1.Columns[4].DataPropertyName = “groupGUID”;

//dg1.Fill(lista);
dg1.AllowUserToAddRows = true;

foreach (Groups item in listGroups)
{
int newline = dg1.Rows.Add();

dg1.Rows[newline].Cells[1].Value = item.Name;
dg1.Rows[newline].Cells[2].Value = item.Description;
dg1.Rows[newline].Cells[3].Value = item.Status;
dg1.Rows[newline].Cells[4].Value = item.GroupGUID;

}

Application.Update(this);

Is it correct ? Or I miss something ?
