    <p>Linq's <code>Single</code> method returns the first and only element of a sequence - if there's more than one element it throws the exception you're seeing. As your table row contains two table cells, its <code>o.Elements()</code> method returns an enumerable with two members, and using <code>Single</code> makes it fall over.</p> <p>Instead of using:</p> <pre><code>control.Controls.Add(constructHtmlStructure(o.Elements().Single())); </code></pre> <p>...use:</p> <pre><code>foreach(var element in o.Elements()) { control.Controls.Add(constructHtmlStructure(element)); } </code></pre> <p>That way you iterate over each of the table row's cells, and add each one to the control.</p> <p><strong>Edit</strong></p> <p>There's another change you need to make. Your dictionary contains exactly one <code>HtmlTableRow</code>, and exactly one <code>HtmlTableRow</code>, both already created by the time you get into <code>constructHtmlStructure</code>. Instead of having pre-existing objects (and therefore only one instance of each available) you should have your dictionary create a new instance of each type on demand.</p> <p>So instead of this (adjusted for spacing):</p> <pre><code>var controlConstructor = new Dictionary&lt;string, HtmlContainerControl&gt; { { "tr", new HtmlTableRow() }, { "td", new HtmlTableCell() } }; ... var control = controlConstructor[o.Name.ToString()]; </code></pre> <p>...try this:</p> <pre><code>var controlConstructor = new Dictionary&lt;string, Func&lt;XElement, HtmlControl&gt;&gt; { { "tr", o =&gt; new HtmlTableRow() }, { "td", o =&gt; new HtmlTableCell() } }; ... var control = controlConstructor[o.Name.ToString()].Invoke(o); </code></pre> <p>You'll also need a function to create an input from an <code>XElement</code>, something like this:</p> <pre><code>private static HtmlControl CreateInputFromElement(XElement element) { // Create an appropriate HtmlInputControl... } </code></pre> <p>...which you can add to your dictionary like this:</p> <pre><code>var controlConstructor = new Dictionary&lt;string, Func&lt;XElement, HtmlControl&gt;&gt; { { "tr", o =&gt; new HtmlTableRow() }, { "td", o =&gt; new HtmlTableCell() }, { "input", CreateInputFromElement } }; </code></pre>

    1. COThanks for your comment! But.. it does not work structure.Cells.Count only returns 1 it could be 2

    2. CONot sure I'm following you - how do you get to call `structure.Cells.Count` if an exception is being thrown? The HTML in your question is a `tr` containing two `td`s; so the first time `constructHtmlStructure` executes, `o` (the `tr`) `.Elements()` (the `td`s) will return two elements. Which is why `Single()` throws the error it does.

    3. COI made the changes that you suggested and structure.Cells.Count returns 1 when each <td> in the string is 1 cell

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.
