    <p><strong>Edited</strong> With .NET 3.5 using LinFu You may use LinFu instead of Castle. However, you would be using reflection anyway, both with Castle's and with Linfu's DynamicProxy, only hidden in the guts of the libraries instead of being exposed in your code. So if your requirement to avoid the use of reflection is out of performance concerns, you wouldn't really avoid it with this solution. In that case I would personally choose Orsol's solution.</p> <p>However: here's an example with LinFu's ducktyping.</p> <pre><code>public interface ISomeType { object Value{get; set;} } public class SomeType1 { public int Value { get; set; } } public class SomeType2 { public string Value { get; set; } } public class SomeTypeWrapperFactory { public static ISomeType CreateSomeTypeWrapper(object aSomeType) { return aSomeType.CreateDuck&lt;ISomeType&gt;(); } } class Program { public static void Main(string[] args) { var someTypes = new object[] { new SomeType1() {Value=1}, new SomeType2() {Value="test"} }; foreach(var o in someTypes) { Console.WriteLine(SomeTypeWrapperFactory.CreateSomeTypeWrapper(o).Value); } Console.ReadLine(); } } </code></pre> <p>Since you don't know the type of the SomeType's until runtime, I would not use mixins, but the visitor pattern (I know this doesn't answer the question on how to use mixins for this, but I just thought I'd throw in my 2 cents).</p> <p><strong>With .NET 4 using dynamic</strong> See <a href="http://code.logos.com/blog/2010/03/the_visitor_pattern_and_dynamic_in_c_4.html" rel="nofollow">Bradley Grainger's post here</a> on using c#4's dynamic keyword to implement the visitor pattern. In your case, reading all the "Value" properties from your dictionary of SomeType's could work like this:</p> <pre><code>public class SomeType1 { public int Value { get; set; } } public class SomeType2 { public string Value { get; set; } } public class SomeTypeVisitor { public void VisitAll(object[] someTypes) { foreach(var o in someTypes) { // this should be in a try-catch block Console.WriteLine(((dynamic) o).Value); } } } class Program { public static void Main(string[] args) { var someTypes = new object[] { new SomeType1() {Value=1}, new SomeType2() {Value="test"} }; var vis = new SomeTypeVisitor(); vis.VisitAll(someTypes); } } </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.
