InfoPath Dev

Hello,

I have an InfoPath 2007 form that I am trying to write C# code to do the following: based on one of the three options a user selects, and then clicking a button, a repeating table would be filled with several rows.

This repeating table is part of the main connection to the database, it is not a secondary data connection (I don't know if that matters or not). To try and get this to work, I've tried code from various sites. They include:

• Deals with Schema validation errors:  http://www.bensonthomaslive.net/1/post/2009/8/infopath-error-schema-validation-found-non-data-type-errors.html
• Can insert a blank row, but no data. If I insert data will only place it on the first row - http://www.infopathdev.com/blogs/jimmy/archive/2009/03/06/automatically-adding-rows-to-repeating-sections.aspx
• http://blogs.msdn.com/b/infopath/archive/2006/11/28/the-xsi-nil-attribute.aspx
• Lots of great examples, but still getting Schema errors - http://www.bizsupportonline.net/infopath2007/4-way-programmatically-add-row-repeating-table.htm

I am familiar with C# but not so good with anything XML (as it pretty obvious at this point).

The data structure is as follows:

 myFields
    dataFields
          Project
              ProjectID
              ProjectTitle
              ProjectDescription
              ProjectTasks
                    ProjectTaskID
                    ProjectTaskDescription
                    ProejctID

ProjectTasks is the repeating table where I want to add multiple rows.

Here's the latest code I have that isn't working:     

 public void CTRL12_7_Clicked(object sender, ClickedEventArgs e)
    {

        
      XPathNavigator myRoot;
      XPathNavigator node;


      myRoot = MainDataSource.CreateNavigator();
      node = myRoot.SelectSingleNode("/dfs:myFields/dfs:dataFields/d:Project", NamespaceManager);
      DeleteNil(node);
 

      string myNamespace = NamespaceManager.LookupNamespace("dfs");      
            using (XmlWriter writer = node.AppendChild())
            {


              writer.WriteStartElement("ProjectTasks", myNamespace);
              writer.WriteElementString("ProjectTaskID", myNamespace, "2");
              writer.WriteElementString("ProjectTaskDescription", myNamespace, "New Description Here");
              writer.WriteElementString("ProjectID", myNamespace, "3");
              writer.WriteElementString("TaskAssignedTo", myNamespace, "16");

              writer.WriteEndElement();
              writer.Close();
            }
      

      
    }

    public void DeleteNil(XPathNavigator node)
    {
      if (node.MoveToAttribute("nil", "http://www.w3.org/2001/XMLSchema-instance"))
        node.DeleteSelf();
    }

Any help on this frustrating problem would be greatly appreciated!

Thank you.
