SharePoint List with InfoPath C#

phamj — Thu, 29 May 2008 01:05:49 GMT

I am trying to do something similar to this click here - utilizing secondary datasource in InfoPath, however in C#. I found another article that connect the secondary data source to a webservice - quite helpful but I still couldn't get around to making it work properly.

// Get a reference to the secondardy datasource

IXMLDOMDocument2 spDOM = (IXMLDOMDocument2)thisXDocument.DataObjects["Contact Details"].DOM;

// Set the SelectionNamspaces to find the correct fields
spDOM.setProperty("SelectionNamespaces", "xmlns:dfs=\"http://schemas.microsoft.com/office/infopath/2003/dataFormSolution\"");

// Get the selected contact text

string selectedContact = thisXDocument.DOM.selectSingleNode("/my:document/my:metadata/my:doc_contact_name").text;

// Get the selected node

spDOM.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:Contact_Details[@Name='" + selectedContact + "']");

// Set the texbox texts
thisXDocument.DOM.selectSingleNode("/my:document/my:metadata/my:doc_contact_role").text = spDOM.documentElement.attributes.getNamedItem("Title").text;

Just wondering if anyone could point out what I'm doing wrong. The error: Object reference not set to an instance of an object

Thanks in advance.
