    <p>I'm trying to find a way to change the serialization behavior of a property.</p> <p>Lets say I have a situation like this:</p> <pre><code>[Serializable] public class Record { public DateTime LastUpdated {get; set; } // other useful properties ... } public class EmployeeRecord : Record { public string EmployeeName {get; set; } // other useful properties ... } </code></pre> <p>Now I want to serialize EmployeeRecord. I don't want the LastUpdated property from the Record class to be serialized. (I do want LastUpdated to be serialized when I serialize Record, though).</p> <p>First I tried hiding the LastUpdated property by using the <em>new</em> keyword and then adding the XmlIgnore attribute:</p> <pre><code>public class EmployeeRecord : Record { public string EmployeeName {get; set; } [XmlIgnore] public new DateTime LastUpdated {get; set; } // other useful properties ... } </code></pre> <p>But that didn't work. Then I tried making the base LastUpdated virtual and overriding it, keeping the attribute:</p> <pre><code>[Serializable] public class Record { public virtual DateTime LastUpdated {get; set; } // other useful properties ... } public class EmployeeRecord : Record { public string EmployeeName {get; set; } [XmlIgnore] public override DateTime LastUpdated {get; set; } // other useful properties ... } </code></pre> <p>This didn't work either. In both attempts the LastUpdated ignored the XmlIgnore attribute and happily went about its business of serializing.</p> <p>Is there a way to make what I'm trying to do happen?</p>

    1. COHow are you serializing it? Because if your using binary serialization, the XmlIgnore attribute won't do much good.

    3. COYou would use the NonSerialized attribute for binary serialization.

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.
