I'm guessing that the new record DOES appear in the grid (you should see it if you scroll up) but it's no longer the last row because of the new sort order. To get around this, you need to bind your DataGrid to a DataView rather than the DataTable. For example:

BindingSource: Orders
BindingSourceMember: Orders.DefaultView

You should also set these binding properties on your New button. Now the problem is determining whether the new row is added as the first row or the last row (depending on how the grid is sorted), and then navigate to that row. To do this, override your form's NavigateNew() method. For example:

public override void NavigateNew()
{
	string SortOrder = ((DataView)this.grdCustomerOrders.DataSource).Sort;
	if (mmString.Empty(SortOrder))
	{
		this.NavigateData(mmNavigate.Last, false);
	}
	else
	{
		// Check the column being sorted and whether it's ascending (the default) or descending,
		// then decide if you should navigate to the first or last row based on where your new row
		// fits into the sort order
		// e.g.: this.NavigateData(mmNavigate.First, false);
	}
}

Best Regards,
