    <p>I am trying to post multiple arrays to my controller using Ajax post. First I have a model like this:</p> <pre><code> public class EnrollmentOptionsVM { public virtual string OptionID{ set;get;} public virtual string UserChoice { set;get;} public virtual string TchOptionID { set; get; } public virtual string TeacherChoice { set; get; } } </code></pre> <p>Then my script:</p> <p></p> <pre><code> &lt;script type="text/javascript"&gt; var $checkboxes = $('input[type="checkbox"]'); var $strInstructors = $('input[name="instructorString"]'); $(document).ready(function () { $('#saveBtn').click(function () { var teacherOptions = []; var options = []; $.each($checkboxes, function () { if ($(this).is(':checked')) { var item = { "UserChoice": "checked", "OptionID": "YouCanSetIDHere" }; } else { var item = { "UserChoice": "unchecked", "OptionID": "YouCanSetIDHere" }; } options.push(item); }) $.each($strInstructors, function () { if ($(this).is(':selected')) { var tchItem = { "TeacherChoice": "checked", "TchOptionID": "SetTchIDHere" }; } else { var tchItem = { "TeacherChoice": "unchecked", "TchOptionID": "SetTchIDHere" }; } options.push(tchItem); }) $.ajax({ type: 'POST', url: '@Url.Action("EnrollmentRefresh", "Student")', contentType: 'application/json', data: JSON.stringify({firstArray:options, secondArray:teacherOptions}) }).done(function (html) { }); }); }); &lt;/script&gt; </code></pre> <p>And in my controller here’s the action signature:</p> <pre><code> [HttpPost] public ActionResult EnrollmentRefresh(List&lt;EnrollmentOptionsVM&gt; checkedOptions) {} </code></pre> <p>When I send only options like this: data: JSON.stringify(options)… it works but when I try to send multiple arrays like the code above it returns null in the controller. How can post multiple arrays using JSON.stringify()?</p> <p>UPDATE 1</p> <p></p> <pre><code> &lt;script type="text/javascript"&gt; var $checkboxes = $('input[type="checkbox"]'); var $strInstructors = $('input[name="instructorString"]'); $(document).ready(function () { $('#saveBtn').click(function () { var teacherOptions = []; var options = []; $.each($checkboxes, function () { if ($(this).is(':checked')) { var item = { "UserChoice": "checked", "OptionID": "YouCanSetIDHere" }; } else { var item = { "UserChoice": "unchecked", "OptionID": "YouCanSetIDHere" }; } options.push(item); }) $.each($strInstructors, function () { if ($(this).is(':selected')) { var tchItem = { "TeacherChoice": "checked", "TchOptionID": "SetTchIDHere" }; } else { var tchItem = { "TeacherChoice": "unchecked", "TchOptionID": "SetTchIDHere" }; } teacherOptions.push(tchItem); }) $.ajax({ type: 'POST', url: '@Url.Action("EnrollmentRefresh", "Student")', contentType: 'application/json', data: JSON.stringify({checkedOptions:options,selectedTeacher:teacherOptions}) }).done(function (html) { }); }); }); &lt;/script&gt; </code></pre> <p>And in the controller:</p> <pre><code> [HttpPost] public ActionResult EnrollmentRefresh( List&lt;EnrollmentOptionsVM&gt; checkedOptions, List&lt;TeacherOptionMV&gt; selectedTeachers) {} </code></pre> <p>Two ViewModels public class TeacherOptionMV {</p> <pre><code> public virtual string TchOptionID { set; get; } public virtual string TeacherChoice { set; get; } } </code></pre> <p>And</p> <pre><code> public class EnrollmentOptionsVM { public virtual string OptionID{ set;get;} public virtual string UserChoice { set;get;} } </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.
