    <p>Below is some code that is used to pass around a reference to a method that contains strings as parameters, the purpose of this question is around using generics to negate the need to define the actual type!</p> <pre><code>Impossible&lt;ExampleSource, string&gt;.Example(c =&gt; c.NonString); //does not work Impossible&lt;ExampleSource, string&gt;.Example&lt;int&gt;(c =&gt; c.NonString); //does work </code></pre> <p><strong>The idea here is to make the first "NonString" call work without having to define the parameter type or declare a new function in Impossible that takes Func&lt;int, TResult&gt;.</strong></p> <pre><code>public static void Example(Expression&lt;Func&lt;TSource, Func&lt;int, TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } //invalid solution... </code></pre> <p><strong>In Java this could be achieved using Func&lt;?, TResult&gt;</strong></p> <pre><code>public class Impossible&lt;TSource, TResult&gt; { public static void Example(Expression&lt;Func&lt;TSource, Func&lt;TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } public static void Example(Expression&lt;Func&lt;TSource, Func&lt;string, TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } public static void Example(Expression&lt;Func&lt;TSource, Func&lt;string, string, TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } public static void Example&lt;T1&gt;(Expression&lt;Func&lt;TSource, Func&lt;T1, TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } public static void Example&lt;T1, T2&gt;(Expression&lt;Func&lt;TSource, Func&lt;T1, T2, TResult&gt;&gt;&gt; function) { Process(function as MethodCallExpression); } private static void Process(MethodCallExpression exp) { if (exp == null) return; Console.WriteLine(exp.Method.Name); } } public class ExampleSource { public string NoParams() { return ""; } public string OneParam(string one) { return ""; } public string TwoParams(string one, string two) { return ""; } public string NonString(int i) { return ""; } } public class Consumer { public void Argh() { Impossible&lt;ExampleSource, string&gt;.Example(c =&gt; c.NoParams); Impossible&lt;ExampleSource, string&gt;.Example(c =&gt; c.OneParam); Impossible&lt;ExampleSource, string&gt;.Example(c =&gt; c.TwoParams); Impossible&lt;ExampleSource, string&gt;.Example&lt;int&gt;(c =&gt; c.NonString); Impossible&lt;ExampleSource, string&gt;.Example(c =&gt; c.NonString); //MAKE THIS WORK } } </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.
