    <p>I've got the following code in my aspx file:</p> <pre><code> &lt;% using (Html.BeginForm()) { int i = 0; %&gt; &lt;% foreach (var item in Model.Educations) { %&gt; &lt;fieldset&gt; &lt;input type="hidden" name="educations.Index" value="" /&gt; &lt;p&gt; &lt;label for="PID"&gt; PID:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].PID", item.PID)%&gt; &lt;%= Html.ValidationMessage("PID", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="EducationType"&gt; EducationType:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].EducationType", item.EducationType)%&gt; &lt;%= Html.ValidationMessage("EducationType", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="SchoolName"&gt; SchoolName:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].SchoolName", item.SchoolName)%&gt; &lt;%= Html.ValidationMessage("SchoolName", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="UniversityId"&gt; UniversityId:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].UniversityId", item.UniversityId)%&gt; &lt;%= Html.ValidationMessage("UniversityId", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="Department"&gt; Department:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].Department", item.Department)%&gt; &lt;%= Html.ValidationMessage("Department", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="Degree"&gt; Degree:&lt;/label&gt; &lt;%= Html.TextBox("educations["+i+"].Degree", String.Format("{0:F}", item.Degree))%&gt; &lt;%= Html.ValidationMessage("Degree", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="YearOfGraduation"&gt; YearOfGraduation:&lt;/label&gt; &lt;%= Html.TextBox("educations[" + i + "].YearOfGraduation", String.Format("{0:F}", item.YearOfGraduation))%&gt; &lt;%= Html.ValidationMessage("YearOfGraduation", "*")%&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="ID"&gt; ID:&lt;/label&gt; &lt;%= Html.TextBox("educations[" + i + "].ID", item.ID)%&gt; &lt;%= Html.ValidationMessage("ID", "*")%&gt; &lt;/p&gt; &lt;input type="submit" name="silButton" value="Sil"/&gt; &lt;/fieldset&gt; &lt;% i++; } %&gt; &lt;p&gt; &lt;input type="submit" name="ekleButton" value="Ekle" /&gt; &lt;/p&gt; &lt;% } %&gt; &lt;div&gt; &lt;%=Html.ActionLink("Back to List", "Index") %&gt; &lt;/div&gt; </code></pre> <p>This way I'm able to dynamically add ("Ekle") more fields if user wants to enter additional education information (most probably from another university or another degree). </p> <p>This code also give "Sil" button (which means delete), and I want to be able to detect exactly which "Sil" button was pressed and delete that Education entry from my "object" in session.</p> <p>My action method looks like this:</p> <pre><code>public ActionResult Step3(string ekleButton, IList&lt;Education&gt; educations, IList&lt;string&gt; silButton) { if (educations != null) { _person.Educations.Clear(); _person.Educations.AddRange(educations); } if (ekleButton != null) { _person.Educations.Add(new Education()); } if (silButton!=null){ //find index and delete it from _person.Edications } return View(_person); } </code></pre> <p>In this way <code>silButton != null</code> if any of the "silButton" buttons was pressed and I can't detect which button was pressed. Is there a way to find this out?</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.

SQuiL has stopped working due to an internal error.

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