    copied!<p>Well, my question is a bit silly, but I've tried lots of different thing without result. </p> <p>I have a ComboBox in my main form and I want to point its data source to the public readonly List PriceChanges list declared in the Filters class. No problem with that but I want to list the Description field. </p> <p>I tried to assign the "Description" string to the DisplayMember attribute without success. My ComboBox only lists: "BusinessLogic.PriceChange" for each entry, where BusinessLogic is the name of my Namespace and PriceChange the class.</p> <p>I appreciate any help. </p> <p>Regards</p> <p>That's part of the code of my main form</p> <pre><code> public mainFrm() { InitializeComponent(); prodFilter = new Filters(); cbPriceChanges.DataSource = prodFilter.PriceChanges; cbPriceChanges.DisplayMember = "Description" } </code></pre> <p>That's is part of the code that declares the List object</p> <pre><code>public enum PriceChangeTypes { No_Change, Increased, Decreased, All } public class PriceChange { public String Description; public readonly PriceChangeTypes Type; public delegate bool ComparisonFuntionDelegate(Decimal a); public readonly ComparisonFuntionDelegate ComparisonFunction; public PriceChange(String Description, PriceChangeTypes type , ComparisonFuntionDelegate CompFunc) { this.Description = Description; Type = type; ComparisonFunction = CompFunc; } } public class Filters { public readonly List&lt;PriceChange&gt; PriceChanges = null; public Filters() { PriceChanges = new List&lt;PriceChange&gt;(); PriceChanges.Add(new PriceChange("No Change", PriceChangeTypes.No_Change, PriceChange =&gt; PriceChange == 0)); PriceChanges.Add(new PriceChange("Increased", PriceChangeTypes.Increased, PriceChange =&gt; PriceChange &gt; 0)); PriceChanges.Add(new PriceChange("Decreased", PriceChangeTypes.Decreased, PriceChange =&gt; PriceChange &lt; 0)); PriceChanges.Add(new PriceChange("All", PriceChangeTypes.All, a =&gt; true)); } } </code></pre>
