Unexpected results from BindingSource.R esetCurrentItem ()

[Geoff]

Hi folks

Calling BindingSource.R esetCurrentItem () is changing the
BindingSource.P osition in a way I don't understand.

If I'm understanding the docs correctly, ResetCurrentIte m()
should simply trigger an event which causes controls to
refresh with the values of the current item with the index
BindingSource.P osition. This is not what I'm seeing.

I'm trying to copy values from the current item to a new
item. In the code below, there are 400 items in the
underlying data (a strongly typed DataTable), and I'm trying
to copy the 100th item.

{
// bindingSource.P osition == 99 as expected

DataRowView fromRow = (DataRowView)bi ndingSource.Cur rent;

string label =
fromRow["label"].ToString().Clo ne().ToString() ;

bindingSource.A ddNew();

// bindingSource.P osition == 400 as expected

DataRowView toRow = (DataRowView)bi ndingSource.Cur rent;
toRow["label"] = label;

// Reset to update the control

bindingSource.R esetCurrentItem ();

// bindingSource.P osition == 97, expected it to be 400
}

I don't understand why the Position is jumping to what seems
to be an arbitrary value.

I'm a C# newbie, so please forgive any basic errors. I'm at
a bit of a loss with this one, so any pointers would be much
appreciated.
