My guess is your XPath of ../ID is incorrect. Right click the node in the datasource task pane and select Copy XPath - what is the path to ID? I'm guessing it may "d:ID" so you'd need ../d:ID instead.

object reference not set to an instance of an object

In Infopath form , I am writing c# code for list item changed event , My requirement is I need to get the ID of the list item which is modified. I tried it by using int id = Int32.Parse(e.Site.SelectSingleNode("../@d:ID", NamespaceManager).Value); I am getting error as - "object reference not set to an instance of an object" Code is - public void TestEmp__Title_Changed(object sender, XmlEventArgs e) { // Write your code here to change the main data source. if (e.Operation == XmlOperation.ValueChange) { if (e.Site.Name == "d:Title" && e.OldValue != e.NewValue) { // Get the ID of the item to be changed int id = Int32.Parse(e.Site.SelectSingleNode("../ID", NamespaceManager).Value); } } When it reaches above step, error gets generated. Can you tell me what change need to be done. Thanks in advance . Regards Indresh
