    <p>Here's another solution, for chained members, including extension methods:</p> <pre><code>public static U PropagateNulls&lt;T,U&gt; ( this T obj ,Expression&lt;Func&lt;T,U&gt;&gt; expr) { if (obj==null) return default(U); //uses a stack to reverse Member1(Member2(obj)) to obj.Member1.Member2 var members = new Stack&lt;MemberInfo&gt;(); bool searchingForMembers = true; Expression currentExpression = expr.Body; while (searchingForMembers) switch (currentExpression.NodeType) { case ExpressionType.Parameter: searchingForMembers = false; break; case ExpressionType.MemberAccess: { var ma= (MemberExpression) currentExpression; members.Push(ma.Member); currentExpression = ma.Expression; } break; case ExpressionType.Call: { var mc = (MethodCallExpression) currentExpression; members.Push(mc.Method); //only supports 1-arg static methods and 0-arg instance methods if ( (mc.Method.IsStatic &amp;&amp; mc.Arguments.Count == 1) || (mc.Arguments.Count == 0)) { currentExpression = mc.Method.IsStatic ? mc.Arguments[0] : mc.Object; break; } throw new NotSupportedException(mc.Method+" is not supported"); } default: throw new NotSupportedException (currentExpression.GetType()+" not supported"); } object currValue = obj; while(members.Count &gt; 0) { var m = members.Pop(); switch(m.MemberType) { case MemberTypes.Field: currValue = ((FieldInfo) m).GetValue(currValue); break; case MemberTypes.Method: var method = (MethodBase) m; currValue = method.IsStatic ? method.Invoke(null,new[]{currValue}) : method.Invoke(currValue,null); break; case MemberTypes.Property: var method = ((PropertyInfo) m).GetGetMethod(true); currValue = method.Invoke(currValue,null); break; } if (currValue==null) return default(U); } return (U) currValue; } </code></pre> <p>Then you can do this where any can be null, or none:</p> <pre><code>foo.PropagateNulls(x =&gt; x.ExtensionMethod().Property.Field.Method()); </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.
