    <p>So I am primarily a C# and Java developer but I suppose this question could pertain to any programming languages that uses StringBuilder or some derivative thereof. </p> <p>Okay so it is more or less common knowledge that concatenate even a small number of strings can be a major performance killer (although even that is debatable). My question is does anyone have knowledge of the performance effects of using a string builder within a string builder. To clarify what I mean by that let me include some dummy code that should help illustrate my point. </p> <p>Also I realize that there is naturally a performance hit by calling multiple instances of StringBuilder but I do not believe that I would be calling it enough to cause any real performance issues. (This assumption may also be wrong any opinion on that would be helpful as well) </p> <pre><code>public string StringToGet() { StringBuilder sb = new StringBuilder("Some Text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append(MethodThatCreatesAnotherString()); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append(MethodThatCreatesAnotherString()); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append(MethodThatCreatesAnotherString()); //etc return sb.toString(); } private string MethodThatCreatesAnotherString() { StringBuilder sb = new StringBuilder("Other text"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); sb.append("more text to add"); return sb.ToString(); } </code></pre> <p>Logic tells me that this shouldn't be a problem, but something about this approach just does not seem to look right to me. Can anyone shed some light on the following questions </p> <ol> <li>Does this create a <em>significantly</em> larger performance hit than just not using additional methods and using a single StringBuilder</li> <li>Is the a reasonably acceptable practice. </li> </ol> <p>Any onsite on this would be greatly appreciated. </p>

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.
