    <p>I'm creating a proof of concept that uses Lambda/LINQ for dynamic where and orderby. The following code works for the where expression, but I can not figure out how to create an order by expression. For this example, if possible I would like to keep it simple; I would rather not write code that modifies an Expression Tree. </p> <pre><code>void Main() { DateTime productSince = DateTime.UtcNow.Subtract(new TimeSpan(1,30,0)); Expression&lt;Func&lt;Products, bool&gt;&gt; filter = d =&gt; d.CreatedDate &gt; productSince &amp;&amp; d.Price &lt; 100 ; List&lt;Products&gt; products = GetProducts(filter, Products); Console.WriteLine(products); } private static List&lt;Products&gt; GetProducts(Expression&lt;Func&lt;Products, bool&gt;&gt; filter, Table&lt;Products&gt; Products) { var products = Products.Where(filter); return products.ToList(); } </code></pre> <p>What I want is similar to the following but can not figure out the code to create the order by expression.</p> <pre><code>void Main() { DateTime productSince = DateTime.UtcNow.Subtract(new TimeSpan(1,30,0)); Expression&lt;Func&lt;Products, bool&gt;&gt; filter = d =&gt; d.CreatedDate &gt; productSince &amp;&amp; d.Price &lt; 100 ; Expression&lt;Func&lt;Products, ????&gt;&gt; orderBy = d =&gt; ??????; List&lt;Products&gt; products = GetProducts(filter, orderBy, Products); Console.WriteLine(products); } private static List&lt;Products&gt; GetProducts(Expression&lt;Func&lt;Products, bool&gt;&gt; filter, Expression&lt;Func&lt;Products, ???&gt;&gt; orderBy, Table&lt;Products&gt; Products) { var products = Products.Where(filter).OrderBy(orderBy); return products.ToList(); } </code></pre> <p>If you are wondering, I'm using LinqPad for this proof of concept.</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.
