Infopath Code to Run Only Once: Infopath Sharepoint

Infopath Code to Run Only Once

Hello,
I have an Infopath form with an onload event that copies data from a seondary data source to the main data source.
The form is submitted to a document library in Sharepoint.
My problem is that when the document is opened post submit, i.e. from the Document library, the code populating the main data source is run again, duplicating the copy from secondary to main data source.
Is there an obvious way to have that code run only once?
Thanks,
dpeadmin

I'm trying to use IsPostBack to address this issue but am getting the error "The name 'IsPostBack' does not exist in the current context.

Any ideas as to what I'm doing wrong.

I'm including the code snippet below.

Thanks,

dpeadmin.

        public void FormEvents_Loading(object sender, LoadingEventArgs e)
        {
            if (!IsPostBack)
            {
 
                XPathNavigator secDSNav = DataSources["Stationery"].CreateNavigator();
 
                // Retrieve the rows of the secondary data source
                XPathNodeIterator rows = secDSNav.Select(
                "/dfs:myFields/dfs:dataFields/dfs:Stationery",
 
                NamespaceManager);
 
                // Loop through the rows of the secondary data source and fill the repeating table
                while (rows.MoveNext())
                {
 
                    string stationery_costs = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Stationery_Costs", NamespaceManager));
                    string number_required = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Number_Required", NamespaceManager));
                    string category = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Category", NamespaceManager));
                    string item = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Item", NamespaceManager));
                    string unit = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Unit", NamespaceManager));
                    string subtotal = GetValueOrEmptyString(rows.Current.SelectSingleNode(
                    "@Subtotal", NamespaceManager));
 
                    // Add the item to the repeating table
                    AddItem(stationery_costs, number_required, category, item, unit, subtotal);
                }
 
 
                // Remove the first empty item from the repeating table
                DeleteFirstEmptyItem();
 
            }
        }
