    <p>I have a text box that I need to pass the <code>authorid</code> into a hidden field that matches the selected author. I then need to pass that <code>authorID</code> to the response.redirect url so the detailed authors page opens with that author's biography information when the button is clicked.<br> Below is my code but it does not work.<br> How can I get my button to work so the correct authorid is passed everytime the author's name is selected?</p> <pre><code>ImageButton btnFindAuthors = sender as ImageButton; HiddenField myhiddenfield = btnFindAuthors.NamingContainer.FindControl("hiddenID") as HiddenField; int myID = Convert.ToInt32(myhiddenfield.Value); Response.Redirect(String.Format("~/Authors_Detail.aspx?id=" + myhiddenfield)); </code></pre> <p>Markup:</p> <pre><code>&lt;asp:TextBox runat="server" ID="txtAuthors" Text='&lt;%# Bind("AuthorName") %&gt;' /&gt; &lt;asp:ImageButton runat="server" ID="btnFindAuthors" OnClick="btnFindAuthors"/&gt; &lt;ajaxToolkit:AutoCompleteExtender ID="fndAuthors" runat="server" DelimiterCharacters="" Enabled="True" ServicePath="~/WebServices/AuthorsWebService.asmx" ServiceMethod="AutoComplete" TargetControlID="txtAuthors" MinimumPrefixLength="3" /&gt; &lt;asp:HiddenField ID="hiddenID" runat="server" Value='&lt;%#Eval("AuthorID") %&gt;' /&gt; </code></pre> <p>Author Id:</p> <pre><code>&lt;asp:SqlDataSource runat="server" ID="sqlAuthors" ConnectionString="&lt;%$ ConnectionStrings:Libros %&gt;" ProviderName="&lt;%$ ConnectionStrings:Libros.ProviderName %&gt;" SelectCommand="SELECT * FROM Authors WHERE AuthorName LIKE ('%' + @Authorname + '%') ORDER BY AuthorName" &lt;selectParameters&gt; &lt;asp:ControlParameter ControlID="txtAuthors" Name="authorname" /&gt; &lt;/selectParameters&gt; &lt;/asp:SqlDataSource&gt; </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
