    <p>I expect there's one of two answers to this, either impossible or extremely simple and I've overlooked the obvious Google query.</p> <p>The underlying issue is that I have a generic object being passed in via an <code>EventHandler</code> that boxes the object and obfuscates the true type; only at runtime do I know what the object is.</p> <p>Admittedly the <code>dynamic</code> keyword can get around the issue, but I'd like to not lose IntelliSense and everything if I can avoid it. Plus, it doesn't solve not knowing what each of the properties of the generic object are without massive amounts of reflection.</p> <p>EDIT: The idea is to be able to determine the true type of the an object in a method parameter, and then cast that object as it's true type without knowing it in advance. This is but a simplified example. Boxed may have been the wrong term.</p> <p>An example:</p> <pre><code>public class Program { static void Main(string[] args) { var container = new Container&lt;Containee&gt;( new Containee { Property1 = Guid.NewGuid(), Property2 = "I'm a property!", Property3 = DateTime.Now } ); var boxed = (object)container; var originalType = boxed.GetType(); // DOES NOT COMPILE: would like an operation like this // EDIT: Request for more detail var actualType = boxed as originalType; actualType.Entity.Property2 = "But I like this better."; } } public class Containee { public Guid Property1 { get; set; } public string Property2 { get; set; } public DateTime Property3 { get; set; } } public class Container&lt;T&gt; { public Container(T entity) { Entity = entity; } public T Entity { get; internal set; } } </code></pre> <p>Clearly that won't compile, as there's not really a way to cast as a variable. However, I'm hoping there's a way to get a reference to the actual object and type, or at least, a way to dynamically re-create the type.</p> <p>I expect there's something simple I'm overlooking, or a better way to get around it in general. The point is to be able to wrap any object in the container, and figure out later what it was.</p>

    1. COI don't see any boxing in your code. You need to do `var actualType = boxed as Container<Containee>;` to make it compilable. `

    2. COBoxing of classes do not happen. Only value types (int, etc) are boxed. The word you are looking for is `casting`. You have casted boxed to object.

    3. COI think the code sample is getting in the way. He mentions an event handler, so think of it as receiving `object sender`. He wants to know if there is any way at compile time to get the real type back and enjoy the benefits of intellisense.

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.
