    <p><strong>I cannot stress enough how bad an idea this design is.</strong> </p> <p><code>ToString()</code> is part of the object contract in .Net. If you don't want to implement it then don't override it, and just let it return the type info. What harm could that possible cause?</p> <p>I don't mean to be so negative, but I am absolutely floored that someone would want to get rid of <code>ToString()</code>.</p> <p><strong>Some additional points:</strong></p> <ol> <li><p>Why do the programmers using this class assume that <code>ToString()</code> will return an ID? Are other classes in your ecosystem doing this? One can argue that <code>ToString()</code> should return some meaningful data. But you really shouldn't be programming against the results of a <code>ToString()</code> call. <code>ToString()</code> is for a string representations of the class, period. This sounds like an education or communication issue between programmers or departments.</p></li> <li><p>Crippling <code>ToString()</code> in any way, whether you can figure out how to at compile time or by throwing an exception at run time, will have ripples. I have <em>never</em> seen this done, and would not expect any class I am using to exhibit this behavior. I think most programmers would have the same expectations. Will future programmers that use your class expect this? What bugs and maintenance nightmares are you causing down the road?</p></li> <li><p>What impact does this have in the IDE or debugger, which rely on <code>ToString()</code>?</p></li> <li><p>What impact will this have when using databinding technologies that don't bind against a specific type, but use reflection at run-time to pull out values? Most databinding will fall back to calling <code>ToString()</code> on an object if a member is not specified to use.</p></li> </ol>

    2. COI agree, but his real problem is that users of his class are incorrectly assuming ToString() gives the object's ID. What would be the best solution to that problem?

    3. COI would ask why they assume ToString() provides an ID? Are there other classes with ToString() returning an ID in the ecosystem? Is this an education/communication problem (not everything should be fixed in code)?

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.
