See my samples in How to access fields and values from an XML Database . The XmlSerializer class can make your code easier; you need to spend time learning how to use the XmlSerializer class but it is worth learning. Is this for an ASP or desktop application? The reason I am not sure is because the forum this question is in implies your application is desktop but DataGrid implies ASP.

Writing to XML files is quite easy in ASP.NET as there are so many objects prepared for you -- you just need the syntax on how to use them. This code shows you how to write a simple member XML file. Sub Page_Load() Dim strCurrentPath As String = Request.PhysicalPath Dim strXMLPath As String = Left(strCurrentPath InStrRev(strCurrentPath \)) & members3.xml Dim objXMLWriter As XmlTextWriter Try objXMLWriter = New XmlTextWriter(strXMLPath Nothing) outDocURL.innerHTML = Writing to file:  & strXMLPath &   Catch objError As Exception outError.innerHTML =  * Error while accessing document .  & objError.Message &   & objError.Source Exit Sub End Try objXMLWriter.Formatting = Formatting.Indented objXMLWriter.Indentation = 3 objXMLWriter.WriteStartDocument() objXMLWriter.WriteComment(Created on  & Now()) objXMLWriter.WriteStartElement(members) objXMLWriter.WriteStartElement(member) objXMLWriter.WriteAttributeString(position regular) Dim intYears As Integer = 4 objXMLWriter.WriteAttributeString(years intYears.ToString(G)) objXMLWriter.WriteElementString(Address 2374 Ash St.) Dim datBirthday As DateTime = #03/05/2000# objXMLWriter.WriteElementString(birthday datBirthday.ToString(yyyy-MM-dd)) Dim intContributions As Integer = 23443 objXMLWriter.WriteElementString(contributions intContributions.ToString(G)) Dim blnLocal As Boolean = True objXMLWriter.WriteElementString(local blnLocal.ToString()) objXMLWriter.WriteEndElement() objXMLWriter.WriteEndElement() objXMLWriter.Flush() objXMLWriter.Close() Dim strXMLResult As String Dim objSR As StreamReader = File.OpenText(strXMLPath) strXMLResult = objSR.ReadToEnd() objSR.Close objSR = Nothing outResults.innerHTML =   & Server.HtmlEncode(strXMLResult) &   End Sub
