    <p>You say you want to cast the object to <code>IRepository&lt;TEntity&gt;</code>, but <code>TEntity</code> is only available at runtime (you have a reference to the <code>Type</code> object in the <code>entityType</code> variable).</p> <p>If <code>IRepository&lt;entityType&gt;</code> were possible, what would you expect to get back from methods such as <code>FindById</code>? Probably an <code>entityType</code> instance, I presume? Now, as <code>entityType</code> could be any type and is only determined at runtime, the compiler cannot possibly know how to compile any code involving <code>entityType</code> variables. Therefore, <code>IRepository&lt;entityType&gt;</code> is not possible.</p> <p>There are two possible solutions, depending on what you want to achieve:</p> <ol> <li>If you do not want to run any code that needs to know about your entity objects, implement an additional <code>IRepository</code>-like interface that handles entities of type <code>object</code> (and possibly throws <code>ArgumentException</code>s if anything is added that does not match the current <code>entityType</code>). Cast the result of your <code>Activator.CreateInstance</code> call to that new interface type.</li> <li>Create a new generic class that takes the entity type as a generic argument. Move all the code that deals with your entities and repositories into that new class, where it always uses the entity type supplied as a generic argument. Instantiate that generic class via <code>Activator.CreateInstance</code> similarly to what you're doing now directly with the <code>TradeSiftRepository&lt;T&gt;</code> class.</li> </ol>

    1. COYes I would expect back an entityType instance. In this particular case all the entities would implement a specific interface.

    2. CO@HadleyHope: The compiler cannot possibly know that, as `entityType` can be anything. You could implement my solution #1 with your entity interface type rather than `object`, however. (Of course, solution #2 works as described, and you can provide your entity interface as a generic constraint.)

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.
