Body
I try to use SurrogatSelector to customize the deserialisation of a stream. It works fine for the root object of the object graph but not for contained objects. See the following code: <pre><code> Stream stream = File.Open("C:\\Temp\\test.bin", FileMode.Create); BinaryFormatter formatter = new BinaryFormatter(); TestToSerialize tts = new TestToSerialize(); formatter.Serialize(stream, tts); stream.Close(); stream = File.Open("C:\\Temp\\test.bin", FileMode.Open); formatter = new BinaryFormatter(); SurrogateSelector ss = new SurrogateSelector(); ss.AddSurrogate(typeof(string), new StreamingContext(StreamingContextStates.All), new StringSerializationSurrogate()); formatter.SurrogateSelector = ss; tts = (TestToSerialize)formatter.Deserialize(stream); stream.Close(); </code></pre> The StringSerializationSurrogate gets called (method SetObjectData) when a string is deserialized, but not when an object containing a string (as a serilizable member) is deserialized. The object to be serialized/ deserialized looks like this: <pre><code> [Serializable] class TestToSerialize { public string s1; public TestToSerialize() { s1 = "some test"; } } </code></pre> Is there a way to have the surrogate get called on non root objects? For completeness the Surrogate looks like this (testcode only to set a breakpoint): <pre><code>sealed class StringSerializationSurrogate : ISerializationSurrogate { public void GetObjectData(Object obj, SerializationInfo info, StreamingContext context) { } public object SetObjectData(object obj, SerializationInfo info, StreamingContext context, ISurrogateSelector selector) { string s = (String)obj; return obj; } } </code></pre>

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.
