    copied!<p>In ASP.NET MVC, if you have a model class like:</p> <pre><code>public class PageModel { public Collection&lt;RowItem&gt; RowItems { get; set; } } public class RowItem { public int Id {get;set;} public string MoreFields { get; set; } } </code></pre> <p>And your javascript adds rows like so: </p> <pre><code>&lt;script type="text/javascript"&gt; var currentRowIndex = 0; $(document).ready(function () { SetFocusEventForInputs('unSelected0'); }); function SetFocusEventForInputs(className) { var inputSelector = '.' + className; $(inputSelector).focusin(function () { AddNewRowTo(this); $(inputSelector).unbind('focusin').removeClass(className); }); } function AddNewRowTo(sendingInputField) { currentRowIndex++; var className = 'unSelected' + currentRowIndex; var collectionNamePrefix = 'RowItems[' + currentRowIndex + '].'; var idField = $('&lt;input/&gt;').attr('name', collectionNamePrefix + 'Id').attr('type', 'text').attr('class', className); var moreFields = $('&lt;input/&gt;').attr('name', collectionNamePrefix + 'MoreFields').attr('type', 'text').attr('class', className); var cell = $('&lt;td&gt;&lt;/td&gt;').append(idField).append(moreFields); var row = $('&lt;tr&gt;&lt;/tr&gt;').append(cell); $(sendingInputField).parents("tr").after(row); SetFocusEventForInputs(className); } &lt;/script&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; &lt;input name="RowItems[0].Id" type="text" class="unSelected0" /&gt; &lt;input name="RowItems[0].MoreFields" type="text" class="unSelected0" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>The default model binder in MVC should resolve it just fine when it gets posted</p> <pre><code>[HttpPost] public ActionResult YourPostActionHere(PageModel model) { var count = model.RowItems.Count(); etc... } </code></pre>
