    <p>I am trying to solve an issue where multiple objects with the same type are selected in a property grid. All these objects provide an array of strings. During my investigations, I figured out that an array can not be edited by the user so I switched to a List and am using a custom editor to edit these strings. That seems to work okay but what ponders me at the moment is that the property is not updated in neither of the selected objects.</p> <p>Let's go into detail with a simple and short example. Let's say you've got this class:</p> <pre><code>public class MyProperties { private List&lt;string&gt; _channels; public MyProperties() { _channels = new List&lt;string&gt;(); } [Editor(@"System.Windows.Forms.Design.StringCollectionEditor," + "System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(System.Drawing.Design.UITypeEditor))] public List&lt;string&gt; Channels { get { return _channels; } } } </code></pre> <p>I am selecting three objects of this type for my property grid:</p> <pre><code>public partial class Form1 : Form { private MyProperties[] _properties; public Form1() { InitializeComponent(); _properties = new MyProperties[3]; for (int i = 0; i &lt; _properties.Length; ++i) _properties[i] = new MyProperties(); propertyGrid1.SelectedObjects = _properties; } } </code></pre> <p>Now, when I'm starting the example, I am able to open the proper string list editor to edit my channel list. When clicking , none of the MyProperties objects contains the configured list of strings.</p> <p>The above example works without problems when only selecting a single instance of MyProperties:</p> <pre><code>propertyGrid1.SelectedObject = _properties[0]; </code></pre> <p>Is there something I'm doing wrong or is something more required to get it to work? Thank you in advance for your efforts!</p>

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.
