    <p>I want to serialize an object. I've got this basic class structure:</p> <pre><code>class Controller { Clock clock; public event EventHandler&lt;ClockChangedEventArgs&gt; ClockChanged; public void serializeProperties() { using (FileStream stream = new FileStream(PROPERTIES_FILE, FileMode.Append, FileAccess.Write, FileShare.Write)) { IFormatter formatter = new BinaryFormatter(); try { formatter.Serialize(stream, clock); } catch (Exception e) { Console.WriteLine(e.Message); } } } public void deserializeProperties() { using (FileStream stream = new FileStream(PROPERTIES_FILE, FileMode.OpenOrCreate, FileAccess.Read, FileShare.Read)) { IFormatter formatter = new BinaryFormatter(); try { clock = (Clock)formatter.Deserialize(stream); } catch (Exception e) { Console.WriteLine(e.Message); clock = new Clock(); } finally { clock.ClockChanged += new EventHandler&lt;ClockChangedEventArgs&gt;(clock_ClockChanged); } } } } </code></pre> <p>The Clock class is defined like this: </p> <pre><code>[Serializable] public class Clock { ClockProperties[] properties; int current; bool isAnimated; public event EventHandler&lt;ClockChangedEventArgs&gt; ClockChanged; public Clock() { properties = new ClockProperties[2]; properties[0] = new ClockProperties("t1"); properties[1] = new ClockProperties("t2"); properties[0].ValueChanged += new EventHandler(Clock_ValueChanged); properties[1].ValueChanged += new EventHandler(Clock_ValueChanged); } } </code></pre> <p>The underlying ClockProperties:</p> <pre><code>[Serializable] public class ClockProperties { public event EventHandler ValueChanged; int posX, posY; string clock; public ClockProperties(string name) { clock = name; } public void OnValueChanged(EventArgs e) { if (ValueChanged != null) { ValueChanged(this, e); } } public string Clock { get { return clock; } set { if (!value.Equals(clock)) { clock = value; OnValueChanged(EventArgs.Empty); } } } public int PosX { get { return posX; } set { if (!(value == posX)) { posX = value; OnValueChanged(EventArgs.Empty); } } } public int PosY { get { return posY; } set { if (!(value == posY)) { posY = value; OnValueChanged(EventArgs.Empty); } } } } </code></pre> <p>When I try to serialize the <code>Clock</code> object with the included Array of <code>ClockProperties</code>, I get an exception that the <code>Controller</code> is not marked serializable. Honestly, I don't understand why. I assumed I only serialize the <code>Clock</code>object, and therefore only mark that class and the <code>ClockProperties</code> as <code>Serializable</code>. Am I missing something?</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.
