    <p>Working in Visual Studio 2008 (C#)... I use a List collection to store instances of my custom class (Shift). </p> <p>I want to delete a certain shift from the list by using the Remove method.</p> <p>But List.Remove() always deletes the first item it finds.</p> <p>I've implemented the IComparable interface for my Shift, I thought this would be enough, then I added an implementation of IEqualityComparer, and it still has no effect.</p> <p>Here's the excerpt with my implementation:</p> <blockquote> <p>region IComparable Members </p> <pre><code> public int CompareTo(object obj) { Shift s1 = this; Shift s2 = (Shift)obj; if (s1.start.time != s2.start.time) return s1.start.CompareTo(s2.start); else return s1.end.CompareTo(s2.end); } </code></pre> <p>endregion</p> <p>region IEqualityComparer Members</p> <pre><code> public bool Equals(Shift x, Shift y) { if ((x.opening) != (y.opening)) return false; if ((x.closing) != (y.closing)) return false; if (!x.opening) if (x._start != y._start) return false; if (!x.closing) if (x._end != y._end) return false; if (x.when != y.when) return false; if (x.day != y.day) return false; if (x.EmployeeID != y.EmployeeID) return false; return true; } public int GetHashCode(Shift obj) { return obj.ToString().ToLower().GetHashCode(); } </code></pre> <p>endregion</p> </blockquote> <p>And yet, still - when the List contains two shifts, say "8:00 - 15:00"; "12:00 - 16:00", calling Remove("12:00-16:00") results in "8:00 - 15:00" getting removed, and the latter one remains in the collection!</p> <p>What's wrong here? Thx</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.
