I think there is a way to solve it if you relax requirement - have array of entities that would allow modifying set of local <code>int</code> variables via operations on array. To do so it is possible to capture references to the variables in an array of delegates that each take <code>ref int val</code>. <pre><code>void Increase(ref int x) { x++; } void Set(ref int x, int amount) { x = amount; } void Sample() { int a = 10; int b = 20; // Array of "increase variable" delegates var increaseElements = new Action[] { () => Increase(ref a), () => Increase(ref b) }; increaseElements[0](); // call delegate, unfortunately () instead of ++ Console.WriteLine(a); // writes 11 // And now with array of "set the variable" delegates: var setElements = new Action<int>[] { v => Set(ref a,v), v => Set(ref b,v) }; setElements[0](3); Console.WriteLine(a); // writes 3 } </code></pre> Notes <ul> <li>directly using delegates you have to call them with ().</li> <li>it may be possible to fix <code>()</code> instead of <code>++</code> issue by wrapping delegate into an object that will call Increase as its <code>++</code> implementation....</li> <li>Issue with <code>Set</code> version where one need to call <code>(3)</code> instead of <code>= 3</code> will require more trickery - implementing custom class with indexing to redirect <code>set [index]</code> to call saved setter function.</li> </ul> Warning: This is really done for entertainment purposes - please don't try it in real 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.
