  1. POSetting the value of a dijit FilteringSelect with saved value
    text
    copied!<p>I have developed a dijit widget for EPiServer. Within the widget there is a FilteringSElect which gets it's data from a REST store. The values that populate the FilteringSelect are a numerical Id and a text value.</p> <p>When EPiServer saves the value, it is the numerical value (Id) that is saved.</p> <p>My entire widget looks like so:</p> <pre><code>{ return declare("communityuser.editors.CommunityUserSelector", [_Widget, _TemplatedMixin, _WidgetsInTemplateMixin, _CssStateMixin, _ValueRequiredMixin], { templateString: "&lt;div class=\"dijitInline\"&gt;\ &lt;div data-dojo-attach-point=\"stateNode, tooltipNode\"&gt;\ &lt;div data-dojo-attach-point=\"inputWidget\" data-dojo-type=\"dijit.form.FilteringSelect\" style=\"width: 300px\"&gt;&lt;/div&gt;&lt;span style=\"padding-left:10px;\"&gt;&lt;a href=\"#\" data-dojo-attach-point=\"resetLink\"&gt;Reset&lt;/a&gt;&lt;/span&gt;\ &lt;/div&gt;\ &lt;/div&gt;", intermediateChanges: false, value: null, store: null, onChange: function (value) { // Event }, postCreate: function () { // call base implementation this.inherited(arguments); // Init textarea and bind event this.inputWidget.set("intermediateChanges", this.intermediateChanges); //set whether the internal required property is true this.inputWidget.set('required', false); //get a reference to the CommunityUserStore var registry = dependency.resolve("epi.storeregistry"); this.store = this.store || registry.get("customquery"); //set the store for the FilteringSelect this.inputWidget.set("store", this.store); //connect the onChange event for the FilteringSelect this.connect(this.inputWidget, "onChange", this._onInputWidgetChanged); //connect the onclick event for the Reset Link this.connect(this.resetLink, "onclick", this._onResetClicked); }, isValid: function () { // summary: // Check if widget's value is valid. // tags: // protected, override return true; }, // Setter for value property _setValueAttr: function (value) { if (!value) { return; } //set the value of the FilteringSelect and the value of the parent control this.inputWidget.set("value", value.userId); this._set("value", this._serializeUser(value)); }, // Event handler for the changed event of the input widget _onInputWidgetChanged: function (value) { this._updateValue(value); }, //Event handler when the Selection in the FilteringSelect is changed _updateValue: function (value) { //check whether the initial value matches the new value i.e. the value after the selection has changed if (this._started &amp;&amp; epi.areEqual(this.value, this._serializeUser(value))) { return; } //create an object representation of the value var formattedValue = (!value) ? {} : this._serializeUser(value); this._set("value", formattedValue); this.onChange(formattedValue); }, _onResetClicked: function (event) { event.preventDefault(); this.inputWidget.reset(); }, _serializeUser: function(userId) { return ({userId: userId }); }, }); </code></pre> <p>This may not be the correct way to write a dojo/dijit widget - it's my first.</p> <p>In my Rest Store I have two methods, Get(string name) and GetUserById(int userId).</p> <p>The values of the Get method are returned, I presume because Get is the default method dojo is looking for. Therefore after loading when the user types a value into the FilteringSelect or selects the pulldown from the FilteringSelect, it is populated with all the values returned from the Get method.</p> <p>However, if when the widget loads it already has a value (because it was saved in EPiServer) I want to call a different method from my store and return just 1 record - in this instance the record to be returned would be a user account that has the same Id.</p> <p>Id | Value 1 | "User 1" 2 | "User 2" 3 | "User 3"</p> <p>What I am struggling with is how to call the method from the store, and then show the value returned in the FilteringSelect.</p> <p>This is the first time I have used either dojo or dijit so i might be doing soemthing fundamentally wrong.</p> <p>Can anyone give me a pointer please?</p> <p>Many thanks Al</p>
