After <code>onHide</code> didn't worked, I found a workaround using getter/setter like:

In my child component:

<pre><code>private _showDialog: boolean = false;

set showDialog(_show: boolean) {
 let result: boolean = this._showDialog != _show;
 if (result == true) {
 this._showDialog = _show;
 this.onCloseDialog.emit({ hasChanges: this.hasChanges, state: this._showDialog });
 }
 }
 get showDialog(): boolean{
 return this._showDialog;
 }
</code></pre>

And in parent template:

<pre><code>&lt;!--View Car Colors Dialog In Parent Component--&gt;
&lt;view-car-colors [showDialog]="showCarColorsDialog" (onCloseDialog)="onCarColorsCloseDialog($event)"&gt;&lt;/view-car-colors&gt;
</code></pre>

In Component, I receive the emit event:

<pre><code>private onCarColorsCloseDialog($event: any): void {
 let result = this.showCarColorsDialog != $event.state;
 if (result == true) {
 this.showCarColorsDialog = $event.state;
 if ($event.hasChanges) {
 this.getCarColors();
 }
 }
}
</code></pre>

I'm using primeng in an angular 2 application and facing this issue <a href="https://stackoverflow.com/questions/43848250/how-to-call-angular-function-when-click-p-dialog-closex-button">(stackoverflow question)</a>

Although the plunkr provided in the accepted answer works but it doesn't in my scenario. I have a separate component that loads the based on an input from the parent component. I want to toggle the visibility flag when the child component is closed/hidden.

Here's the code snippet 

<pre><code> &lt;p-dialog header="Assets Management" [(visible)]="showDialog" modal="modal" [closable]="true" (onHide)="close()" appendTo="body"&gt;
 .. some content ..
 &lt;/p-dialog&gt;
</code></pre>

In component, I have:

<pre><code>@Component({
 selector: 'view-car-colors',
 templateUrl: '/view-car-colors.html',
 inputs: ['showDialog'],
 outputs: ["onCloseDialog"],
})
export class ViewCarColorsComponent {
 private showDialog: boolean = false; //default close
 private onCloseDialog: EventEmitter&lt;any&gt; = new EventEmitter();

 public close(): void {
 this.showDialog = false;
 //emit this to its parent
 this.onCloseDialog.emit({ hasChanges: true });
 }
}
</code></pre>

And finally in my parent component, I am calling it like:

<pre><code>&lt;view-car-colors [showDialog]="showCarColorsDialog" (onCloseDialog)="onCarColorsCloseDialog($event)"&gt;&lt;/view-car-colors&gt;
</code></pre>

Where <code>showCarColorsDialog</code> is changed based on a button click.

<pre><code>private onCarColorsCloseDialog($event: any): void {
 this.showCarColorsDialog = false;
 if ($event.hasChanges) {
 //fetch the changes again
 this.getCarColors();
 }
}
</code></pre>

I have used the primeng controls on multiple places and they all work fine but just has this issue so I'm sure it can't be because of the version.

我在angular 2应用程序中使用primeng，面对这个问题(stackoverflow question) 虽然接受答案中提供的plunkr有效，但在我的场景中不起作用。我有一个单独的组件，它根据来自父组件的输入加载。我希望在子组件关闭/隐藏时切换可见性标志。 下面是代码片段 <p-dialog header...
