    <p>I have the following html binding in knockout</p> <pre><code>&lt;div data-bind="with: talkData"&gt; &lt;div data-bind="foreach: Talks"&gt; &lt;p data-bind="text: Title"&gt;&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; &lt;p&gt; &lt;button class="btn btn-success previous" data-bind="click: $root.PageBack, disable: $root.page() == 1"&gt;Prev&lt;/button&gt; &lt;button class="btn btn-success next" data-bind="click: $root.PageNext, disable: $root.page() == $root.talkData().TotalPageCount"&gt;Next&lt;/button&gt; &lt;/p&gt; </code></pre> <p>With the following model:</p> <pre><code>$(function() { function TalksViewModel() { var self = this; self.page = ko.observable(1); self.records = ko.observable(1); self.totalPages = ko.observable(1); self.talkData = ko.observable(); self.IsPrevEnabled = isPrevEnabled; function pageBack(item) { self.page(self.page() - 1); loadDataFromServer(); } self.PageBack = pageBack; function pageNext(item) { console.log("page next"); self.page(self.page() + 1); loadDataFromServer(); } self.PageNext = pageNext; function loadDataFromServer() { var url = '/Talks/GetPagedTalks'; self.talkData(null); $.get(url, { page: self.page() }, self.talkData); } // Initial page loadDataFromServer(); } ko.applyBindings(new TalksViewModel()); }); </code></pre> <p>The JSON returned from the 'GetPagedTalks' call is:</p> <pre><code>Talks: [{Title:Philippians 1:12-26,…}, {Title:Philippians 1:1-11,…}, {Title:Devoted Lives: ,…}] 0: {Title:Philippians 1:12-26,…} 1: {Title:Philippians 1:1-11,…} 2: {Title:Devoted Lives: ,…} TotalPageCount: 59 TotalRowCount: 177 </code></pre> <p>The next and previous buttons work but I'm really struggling to know how to set the total number of pages from the data returned from the GET call.</p> <p>The line: disable: $root.page() == $root.talkData().TotalPageCount</p> <p>Isn't working at all. I assumed TotalPageCount would be part of talkData.</p> <p>Any help appreciated.</p> <p>Thanks.</p>

Guidance
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).
