Instead of opening & closing multiple times database connection you can define mutiple dataset based on number of controls and open a connection once in the load event populate all the datasets based on different sql query for populating different controls and once you finish then close the database connection. Now you can bind corresponding dataset to different controls. Hope this way you can avoid mutiple database trip and a performance gain as well Share knowledge to enhance your learning

Thanks a lot I have found the solution and you are right we should mention only "OrigoNS" as namespace prefix. Also it should call the 1st overloaded method of SelectSingleNode passing the XmlNamespaceManager object in the 2nd parameter. Corrected code XmlDocument objXmlDoc = new XmlDocument(); objXmlDoc.Load("C:\\abc.xml"); objRoot=objXmlDoc.DocumentElement; XmlNamespaceManager objXmlNS = new XmlNamespaceManager(objXmlDoc.NameTable); objXmlNS.AddNamespace("OrigoNS","http://www.origoservices.com"); XmlNode objRoot; string MsgID=objRoot.SelectSingleNode("//OrigoNS:message_id",objXmlNS).InnerText; Share knowledge to enhance your learning
