    data
    text
    <p>I have a <strong>MVC 3</strong> page that returns a list of user responses with a partial view called "memo" (which displays/add memos) for each response. When I add a memo to a response, it should update the db and the list of memos for that response. It should be partial page update via ajax, which effects only the partial view "memo". </p> <p>The view Response.chtml that contains "memo":</p> <pre><code>@using (Html.BeginForm("Response", "User", FormMethod.Post, new { id = "UserResponse" })) { .... code removed .... @foreach (var response in Model) { &lt;div class="qna"&gt;&lt;input type="text" id=@response.responseId value="@response.ResponseText" /&gt; &lt;div&gt;@Html.Partial("_memo", response.responseId)&lt;/div&gt; } ..... </code></pre> <p>The partial page "_memo.chtml":</p> <pre><code>&lt;div&gt;add memo&lt;/div&gt; &lt;ul id="memos"&gt; @foreach (var memo in Model) { &lt;li&gt;@memo.Text&lt;/li&gt; } &lt;/ul&gt; &lt;form method="post" id="memoForm" action="@Url.Action("AddMemo")"&gt; @Html.TextArea("Memo", new { rows = 5, cols = 50 }) &lt;br /&gt; &lt;input type="submit" value="Add" /&gt; &lt;/form&gt; </code></pre> <p>Controller for view User/Response:</p> <pre><code>[HttpGet] public ActionResult Response(id) { ..... return View(responses); </code></pre> <p>I just started with the code above, need help filling the blanks. </p> <ol> <li><p>If I pass the response Id to the partial view, how do I pull the list of memos for that response? Will it involve ajax? (instead of ..<code>Partial("_memo", response.memos)</code>)</p></li> <li><p>How do I update the partial view via ajax call. What is ajax call (sample code) on the client side and how would the controller look? When the ajax call is successful, how do I update the list memos <code>div="memos"</code> to reflect the new memo? </p></li> <li><p>Will the form action from Response conflict with form action of the partial view Memo?</p></li> </ol>

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.
