How to read & write value from Infopath Datasource throught C#

Hi,

In a requirement, we need to display views based on the current user who updates the infopath form. So I thought let me write the logic to read and store values in Info path Data source from code behind. Following Code useful.

Read:
XPathNavigator nav = MainDataSource.CreateNavigator();
string fieldValue = nav.SelectSingleNode("//my:Myfield1", NamespaceManager).Value;

Write:
XPathNavigator nav = MainDataSource.CreateNavigator();
nav.SelectSingleNode("//my:Myfield1", NamespaceManager).SetValue("NewValue");

essential Namespace is Microsoft.Office.InfoPath;

Hope it helps...

Best Regards
