    <p>I don't know if having a guideline for short lambda's and delegates is really useful. However, have a guideline for having short functions. The methods I write are on average 6 or 7 lines long. Functions should hardly ever be 20 lines long. You should create the most readable code and if you follow <a href="http://rads.stackoverflow.com/amzn/click/0132350882" rel="nofollow noreferrer">Robert Martin's</a> or <a href="http://rads.stackoverflow.com/amzn/click/0735619670" rel="nofollow noreferrer">Steve McConnell's</a> advice, they tell you to keep functions short and also keep the inner part of loops as short of possible, favorably just a single method call.</p> <p>So you shouldn't write a for loop as follows:</p> <pre><code>for (int i = 0; i &lt; 100; i++) { // Potentially significant amounts of code } </code></pre> <p>but simply with a single method call inside the loop:</p> <pre><code>for (int i = 0; i &lt; 100; i++) { WellDescribedOperationOnElementI(i); } </code></pre> <p>With this in mind, while I in general agree with Jon Skeet’s answer, I don't see any reason why you shouldn't want his example to be written as:</p> <pre><code>Parallel.For(0, 100, i =&gt; { WellDescribedPartOfHeavyCalculation(i); }); </code></pre> <p>or</p> <pre><code>Parallel.For(0, 100, i =&gt; WellDescribedPartOfHeavyCalculation(i)); </code></pre> <p>or even:</p> <pre><code>Parallel.For(0, 100, WellDescribedPartOfHeavyCalculation); </code></pre> <p>Always go for the most readable code, and many times this means: short anonymous methods, and short lambda's, but most of all short -but well described- methods.</p>

    1. COYour answer was ironic for me. Had I just guessed, I might imagine responders would say at best "lambdas should be same length or shorter than functions" not "lambdas short, and functions even shorter." What is it that makes functions harder to read than lambdas?

    2. COBecause lambdas are usually part of a method, it is practially impossible to make a method shorter than a lambda. Methods aren't harder to read than lambdas. No, I think that excessive use of lambdas could make your code less readable. With great power, yada yada.

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.
