    <p>I'm attempting to iterate over the ListViewDataItems in an ASP.Net ListView, and use the ListView.ExtractItemValues to get the values from DataBoundControls. This works fine with ITextControls, but I am having difficulty getting the Selected Item from a RadioButtonList. </p> <p>Here is my markup:</p> <pre><code>&lt;asp:ListView ID="lvQuiz" runat="server"&gt; &lt;LayoutTemplate&gt; &lt;fieldset&gt; &lt;ul&gt; &lt;asp:PlaceHolder ID="itemplaceholder" runat="server"&gt;&lt;/asp:PlaceHolder&gt; &lt;/ul&gt; &lt;/fieldset&gt; &lt;asp:Button ID="cmdSubmit" runat="server" Text="Submit" OnClick="cmdSubmit_Click" /&gt; &lt;/LayoutTemplate&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;fieldset&gt; &lt;legend&gt; &lt;asp:Label ID="lblQuestionText" runat="server" Text='&lt;%# Bind("Question.QuestionText") %&gt;' /&gt; &lt;/legend&gt; &lt;asp:RadioButtonList ID="rblResponse" runat="server" DataTextField="ResponseText" DataValueField="Id" DataSource='&lt;%# Bind("Question.PossibleResponses") %&gt;'&gt; &lt;/asp:RadioButtonList&gt; &lt;/fieldset&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; </code></pre> <p></p> <p>And here is the code where I am trying to extract the values:</p> <pre><code>var Q = (Quiz)Session["Quiz"]; foreach (var item in lvQuiz.Items) { var itemValues = new OrderedDictionary(); lvQuiz.ExtractItemValues(itemValues, item, true); var myQuestion = Q.UserResponses.Keys .Where(x =&gt; x.QuestionText == itemValues["Question.QuestionText"]) .Single(); Q.UserResponses[myQuestion] = itemValues["Question.PossibleResponses"].SelectedItem } </code></pre> <p>My problem lies with that last line there. "Question.PossibleResponses" is bound to the RadioButtonList, but the value for itemValues["Question.PossibleResponses"] returns a list of ALL my RadioButtonList's options. How do I tell which one the user selected?</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.
