    <p>I have a fairly complex inheritance hierarchy including generics and we are trying to use protobuf .net for serialization purposes. Unfortunately it does not seem to be able to handle this case correctly. This is how the hierarchy looks like.</p> <pre><code> [System.Runtime.Serialization.DataContract] [ProtoBuf.ProtoInclude(1000, typeof(GenericBaseClass&lt;object&gt;))] [ProtoBuf.ProtoInclude(1001, typeof(GenericBaseClass&lt;string&gt;))] public abstract class BaseClass { public int BaseProperty1 { set; get; } public int BaseProperty2 { set; get; } public BaseClass() { } } [System.Runtime.Serialization.DataContract] [ProtoBuf.ProtoInclude(1002, typeof(GenericDerivedClass&lt;object&gt;))] [ProtoBuf.ProtoInclude(1003, typeof(GenericDerivedClass&lt;string&gt;))] public abstract class GenericBaseClass&lt;T&gt; : BaseClass { /// &lt;summary&gt; /// /// &lt;/summary&gt; [System.Runtime.Serialization.DataMember(Order = 5)] public T ResponseProperty { get; set; } public GenericBaseClass() { } } [System.Runtime.Serialization.DataContract] [ProtoBuf.ProtoInclude(1004, typeof(DerivedClass1))] [ProtoBuf.ProtoInclude(1005, typeof(DerivedClass2))] public abstract class GenericDerivedClass&lt;T&gt; : GenericBaseClass&lt;T&gt; { public int AdditionalProperty { get; set; } public GenericDerivedClass() { } } </code></pre> <p>Finally these classes are implemented by two closed constructed non generic classes</p> <pre><code> [System.Runtime.Serialization.DataContract] public class DerivedClass1 : GenericDerivedClass&lt;string&gt; { [System.Runtime.Serialization.DataMember(Order = 6)] public int DerivedClass1Property { set; get; } } [System.Runtime.Serialization.DataContract] public class DerivedClass2 : GenericDerivedClass&lt;object&gt; { [System.Runtime.Serialization.DataMember(Order = 7)] public int DerivedClass2Property { set; get; } } </code></pre> <p>I have written the following test method to serialize these and it is giving me error.</p> <pre><code> [TestMethod] public void SerializeDeserializeAndCompare() { DerivedClass2 i = new DerivedClass2() { BaseProperty1 = 1, BaseProperty2 = 2, DerivedClass2Property = 3, ResponseProperty = new Object() }; using (var file = System.IO.File.Create("test.bin")) { ProtoBuf.Serializer.Serialize(file, i); } using (var file = System.IO.File.OpenRead("test.bin")) { var o = ProtoBuf.Serializer.Deserialize&lt;DerivedClass2&gt;(file); } } </code></pre> <p>The error I am getting is </p> <p>ProtoBuf.ProtoException: A type can only participate in one inheritance hierarchy (CapitalIQ.DataGet.UnitTests.DataSetUnitTest+DerivedClass2) ---> System.InvalidOperationException: A type can only participate in one inheritance hierarchy</p> <p>Is this a limitation of protobuf .net or am I doing something incorrect. I am using r282 version.</p> <p>Thanks Shobhit</p>

    1. COSomething like that should work. I'm on "kids duty" at the moment, but will look later

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.
