    <p>I need help with a special mapping with AutoMapper. I want to map a collection of objects to a collection of strings.</p> <p>So i have a Tag classd</p> <pre><code>public class Tag { public Guid Id { get; set; } public string Name {get; set; } } </code></pre> <p>Than in a model i have a IList of this class. Now i want to map the name's to a collection of strings.</p> <p>Thats how I define the mapping rule:</p> <pre><code>.ForMember(dest =&gt; dest.Tags, opt =&gt; opt.ResolveUsing&lt;TagNameResolver&gt;()) </code></pre> <p>And here is my ValueResolver:</p> <pre><code>protected override string ResolveCore(Tag source) { return source.Name; } </code></pre> <p>But u know.. it dont work ;-) So maybe someone know how to do it right and can help me.</p> <p>thx alot</p> <p>Jan</p> <p>Sooo.. u wanted more details.. here u get it.. but i have shorten it ;)</p> <p>So the Model:</p> <pre><code>public class Artocle { public Guid Id { get; set; } public string Title {get; set; } public string Text { get; set; } public IList&lt;Tag&gt; Tags { get; set; } } </code></pre> <p>And the Tag model u can see above.</p> <p>I want to map it to a ArticleView... i need the tag model only for some business context, not for tthe output.</p> <p>So here is the ViewModel i need to map to:</p> <pre><code>public class ArticleView { public Guid Id { get; set; } public string Title { get; set; } public string Text { get; set; } public IList&lt;string&gt; Tags { get; set; } // The mapping problem :-) } </code></pre> <p>So I have a BootStrapper for the mappings. My Mapping looks like this:</p> <pre><code>Mapper.CreateMap&lt;Article, ArticleView&gt;() .ForMember(dest =&gt; dest.Tags, opt =&gt; opt.ResolveUsing&lt;TagNameResolver&gt;()) </code></pre> <p>And I map it manuelly with a special method</p> <pre><code> public static ArticleView ConvertToArticleView(this Article article) { return Mapper.Map&lt;Article, ArticleView&gt;(article); } </code></pre>

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.
