Body
This post goes to a gap in my understanding of C# classes and why they are preferable to static functions. I am trying to get a List of objects. Each object in the list represents a record in a table. This would be easy to do in a static function. Using a class, I've been able to do it as follows: Calling routine: <pre><code>ListOfBusinesses l = new ListOfBusinesses (); List<Business> b = l.listBusinesses(); </code></pre> The classes: <pre><code> public class Business { public string Bupk { get; set; } public string Bu_name { get; set; } } public class ListOfBusinesses { public List<Business> listBusinesses() { List<Business> businesses = new List<Business>(); businesses.Add(new Business("1", "Business Name 1")); businesses.Add(new Business("2", "Business Name 2")); return businesses; } } </code></pre> Couldn't I rewrite the class so that this could be done with one line: <pre><code>ListOfBusinesses l = new ListOfBusinesses(); </code></pre> It seems to me like the ListofBusinesses class above is nothing but a static function wrapped in a class which has no properties and is only there for the sake of having a class. I tried: <pre><code>public class ListOfBusinesses { List<Business> businesses; public List<Business> ListOfBusinesses() { List<Business> businesses = new List<Business>(); businesses.Add(new Business("1", "Business Name 1")); businesses.Add(new Business("2", "Business Name 2")); return businesses; } } </code></pre> But received the compiler error "member names cannot be the same as there enclosing type". Eg, I tried to use a constructor, but am missing something. Any help would enlighten me in an area I have misunderstood for some time. Mike Thomas

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.
