    <p>I am trying to create a custom placeholder control. Here is the code excerpt:</p> <pre><code>(function () { var Placeholder = WinJS.Class.define(function ctor(elem, options) { this.element = elem || document.createElement('div'); this.element.winControl = this; WinJS.UI.setOptions(this, options); this.init(); }, { element: { get: function () { return this._element; }, set: function (value) { this._element = value; } }, placeholder: { get: function () { return this._placeholder; }, set: function (value) { this._placeholder = value; this._placeholderElement.textContent = value; } }, placeholderClass: { get: function () { return this._placeholderClass; }, set: function (value) { this._placeholderClass = value; this._placeholderElement.classList.add(value); } }, _placeholderElement: null, init: function () { this._addPlaceholder(); }, _addPlaceholder: function () { /* Code to add placeholder. */ } }); WinJS.Namespace.define("ControlX", { Placeholder: Placeholder }); })(); </code></pre> <p>I am trying to use this control in the html in this manner :</p> <pre><code>&lt;div data-win-control="ControlX.Placeholder" data-win-res="{winControl:{placeholder:'resHeight'}}"&gt;&lt;input type="text"/&gt;&lt;/div&gt; </code></pre> <p>When I set the placeholder value using the <code>data-win-res</code> attribute, I am getting an exception: </p> <blockquote> <p>"Unable to set property 'placeholder' of undefined or null reference"</p> </blockquote> <p>According to this article: <a href="http://msdn.microsoft.com/en-us/library/windows/apps/jj673579.aspx" rel="nofollow">How to localize WinJS controls</a> we can bind resource strings to winControl attributes too.</p> <p>What am I doing wrong?</p> <p>Is there any other way to bind resource string to a winControl property?</p>

    1. COIs your control in a Page Control? If so, are you calling WinJS.Resources.processAll(element) during the PageControls' ready function? I seem to be able to get this to work, though I can't tell what may be different between our two efforts.

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.
