    <p>I have a Winform with a very basic premise: modify 2 string properties of an object that is passed into it, then save it to disk when the form closes. I am trying to use databinding to bind the Text properties of 2 textboxes on the form to the 2 string properties of the object.</p> <p>But it isn't working. The textboxes never display the values I am assigning to the object properties in the constructor. And when I type something into the textboxes, the object properties are not getting updated. What am I doing wrong?</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Xml; using System.Xml.Serialization; namespace Eds_Viewer { public partial class EdsConfigForm : Form { public EdsConfigForm(EdsConfig myconfig) { InitializeComponent(); EdsConfig = myconfig; if (EdsConfig.VFPConnectionString == null) //set a default value { EdsConfig.VFPConnectionString = "Provider=vfpoledb;Data Source=g:\\eds\\"; } if (EdsConfig.VFPFileName == null) //set a default value { EdsConfig.VFPFileName = "InvoiceDB"; } this.VFPConnectionStringTextbox.DataBindings.Add("Text", EdsConfig, "VFPConnectionString"); this.VFPFileNameTextbox.DataBindings.Add("Text", EdsConfig, "VFPFileName"); } EdsConfig EdsConfig; private void SaveConfigToDisk(EdsConfig myconfig) { XmlSerializer x = new XmlSerializer(typeof(EdsConfig)); TextWriter tw = new StreamWriter("EdsConfig.xml"); x.Serialize(tw, myconfig); tw.Close(); } private void EdsConfigForm_FormClosing(object sender, FormClosingEventArgs e) { this.SaveConfigToDisk(this.EdsConfig); } } } </code></pre>

    2. COWhoops, the BindingSource line was something I was playing with... not a valid part of the problem. Edited out.

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.
