    <p>I have a <code>textarea</code> in my MVC application where I'm implementing <code>AspNetSpellCheck</code>, the debugger tells me that the <code>textarea</code> changes to <code>display: none; visibility: hidden;</code> and a <code>div</code> is generated with <code>id="abc"</code> and <code>class"="pqr"</code>.</p> <pre><code>&lt;input type="hidden" value="" name="userid" id="useid" /&gt; </code></pre> <p>Also I'm implementing change detection for all text area/other controls....</p> <pre><code>var somethingChanged = false; $(document).ready(function() { $('input').change(function() { somethingChanged = true; }); }); </code></pre> <p>Because the text area becomes hidden, I suppose it doesn't automatically fire the <code>change()</code> event. What is the solution to fire the event in above case? Thanks! </p> <p><strong>EDIT</strong></p> <p>With AspNetSpellCheck, below is my code,</p> <pre><code> @{ ASPNetSpell.Razor.SpellAsYouType mySpell = new ASPNetSpell.Razor.SpellAsYouType(); mySpell.InstallationPath = ("/Content/ASPNetSpellInclude"); mySpell.FieldsToSpellCheck = "TextArea1"; } &lt;textarea id="TextArea1" cols="20" rows="2"&gt;bedddly&lt;/textarea&gt; @Html.Raw(mySpell.getHtml()) &lt;script type="text/javascript" language="javascript"&gt; $(document).ready(function () { $('input[type="hidden"]').change(function () { debugger; alert('hi'); // somethingChanged = true; }); }); &lt;/script&gt; </code></pre> <p>Debugger produce below code, text area hidden and a new DIV construct,</p> <pre><code> &lt;div tabIndex="null" class="livespell_textarea" id="TextArea1___livespell_proxy"&gt; &lt;textarea id="TextArea1" style="display: none; visibility: hidden;" rows="2" cols="20"&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).
