I need a way to recognize the textbox on code-behind.</p> <p>Thanks</p> <p>Following is my code:</p> <p>Default.aspx:</p> <pre><code>//code behind on @page directive &lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="WebApplication2.WebForm1"%&gt; // Getting the value from XML Agentname.Text = root.SelectSingleNode("name").ChildNodes[0].Value; // Assigned a textbox asp:TextBox ID="Agentname" runat="server" disabled="true" MaxLength="57" / (removed angel bracket as SO is ignoring this line, don't know why) //Code behind using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; namespace WebApplication2 { public partial class WebForm1 : System.Web.UI.Page { public void SaveXml(object sender, EventArgs e) { XDocument xmlDoc = XDocument.Load(Server.MapPath("Agent.xml")); Console.WriteLine("read XML"); var person = xmlDoc.Descendants("agent"); person.ElementAt(0).Value = ""; xmlDoc.Element("agent").Add(new XElement("name", Agentname.Text)); xmlDoc.Save(Server.MapPath("Agent.xml")); } } } </code></pre>

    2. CONot sure what you mean by this comment: "(removed angel bracket as SO is ignoring this line, don't know why)". You need the < and > at the beginning and end of defining that textbox.

    3. COI was referring to the edit box in Stack Overflow. Not on my code. I have angle brackets there. I found an answer from "asawyer". Thanks for looking.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
