    <p>I have a Player class and a Stat class. The Player class has a List property where PlayerStat has a List and XP properties. I think my design is flawed because I am having trouble doing things that I think should be easy. I want to list out all Players and their XP for all Stats. Below are more details of the classes and the GetCompletePlayerStats method which is what I really don't like. I basically need to list out the XP for all stats for a Player, if the player doesn't have a stat then it should have an XP of zero. Any design help/suggestions would be appreciated.</p> <pre><code>public class Stat : EntityBase{ public virtual string Name { get; set; } public virtual UnitOfMeasure Unit { get; set; } public virtual int UnitXP { get; set; } } public class Player : EntityBase{ public virtual string Name { get; set; } public virtual IList&lt;PlayerStat&gt; PlayerStats { get; set; } public virtual List&lt;PlayerStat&gt; GetCompletePlayerStats(IQueryable&lt;Stat&gt; stats) { var allStats = new List&lt;PlayerStat&gt;(); var playerStatIds = PlayerStats.Select(ps =&gt; ps.PlayerStatistic.Id).ToList(); if (playerStatIds.Count == 0) { allStats.AddRange(stats.Select(stat =&gt; new PlayerStat() {PlayerStatistic = stat, XP = 0})); } else { var zeroStats = stats.Where(s =&gt; !playerStatIds.Contains(s.Id)).ToList(); allStats.AddRange(zeroStats.Select(zeroStat =&gt; new PlayerStat() {PlayerStatistic = zeroStat, XP = 0})); allStats.AddRange(PlayerStats); } return allStats; } } public class PlayerStat : EntityBase{ public virtual Stat PlayerStatistic { get; set; } public virtual double XP { get; set; } } </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.
