    <p>I have the following enumeration:</p> <pre><code>public enum AuthenticationMethod { FORMS = 1, WINDOWSAUTHENTICATION = 2, SINGLESIGNON = 3 } </code></pre> <p>The problem however is that I need the word "FORMS" when I ask for AuthenticationMethod.FORMS and not the id 1.</p> <p>I have found the following solution for this problem (<a href="http://www.codeproject.com/Articles/11130/String-Enumerations-in-C" rel="noreferrer">link</a>):</p> <p>First I need to create a custom attribute called "StringValue":</p> <pre><code>public class StringValue : System.Attribute { private readonly string _value; public StringValue(string value) { _value = value; } public string Value { get { return _value; } } } </code></pre> <p>Then I can add this attribute to my enumerator:</p> <pre><code>public enum AuthenticationMethod { [StringValue("FORMS")] FORMS = 1, [StringValue("WINDOWS")] WINDOWSAUTHENTICATION = 2, [StringValue("SSO")] SINGLESIGNON = 3 } </code></pre> <p>And of course I need something to retrieve that StringValue:</p> <pre><code>public static class StringEnum { public static string GetStringValue(Enum value) { string output = null; Type type = value.GetType(); //Check first in our cached results... //Look for our 'StringValueAttribute' //in the field's custom attributes FieldInfo fi = type.GetField(value.ToString()); StringValue[] attrs = fi.GetCustomAttributes(typeof(StringValue), false) as StringValue[]; if (attrs.Length &gt; 0) { output = attrs[0].Value; } return output; } } </code></pre> <p>Good now I've got the tools to get a string value for an enumerator. I can then use it like this:</p> <pre><code>string valueOfAuthenticationMethod = StringEnum.GetStringValue(AuthenticationMethod.FORMS); </code></pre> <p>Okay now all of these work like a charm but I find it a whole lot of work. I was wondering if there is a better solution for this.</p> <p>I also tried something with a dictionary and static properties but that wasn't better either.</p>

    1. CONice! I can use this to translate enum values to localized strings.

    2. COWhile you may find this long winded, it's actually a pretty flexible way to go for other things. As one of my colleagues pointed out, this could be used in many cases to replace Enum Helpers that map database codes to enum values etc...

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.
