I have custom widget which is used to fetch data.

On button click i am opening the widget B to populate details data.

I don't want to show the details widget b in Anchorcontroller. I am using Launchpad theme .

Is there a way i can remove the widget B from AnchorController and just open it from Custom Widget button click.

Thanks in Advance.

Kafil,

  Sure here are the steps:

  1. Make sure your widget IS added to the anchorbarcontroller.
  2. In the apps main config.json add a "visible: false" to your widgets object.
          {
    "name": "eSearch",
    "version": "2.13.1",
    "uri": "widgets/eSearch/Widget",
    "config": "configs/eSearch/config_widgets_eSearch_Widget_44.json",
    "index": 6,
    "id": "widgets_eSearch_Widget_44",
    "visible": false
    }
  3. Next add this code to your other widgets button:
              var pm = PanelManager.getInstance();
    var widgetCnfg = null;
    array.some(this.appConfig.widgetPool.widgets, function(aWidget) {
    if(aWidget.name == 'eSearch') {
    widgetCnfg = aWidget;
    return true;
    }
    return false;
    });
    widgetCnfg.visible = true;
    pm.showPanel(widgetCnfg).then(lang.hitch(this, function(panel){
    panel.setPosition({ top: 120, left: 10, width: 350, height: 480, margin: 10, index: 1 });
    pm.normalizePanel(panel);
    }));
  4. Don't forget to add PanelManager to your widget define array.

Thanks for the help Robert.

I tried but not working.

Let me give u my code what exactly i am doing.

I have a details button in my dgrid.

grdTest.on(".field-det:click", lang.hitch(this, function(e){

   if (e.target.alt) {

  var paramvalues = e.target.alt;

 document.getElementById('RegNo').value = paramvalues

document.getElementById('publishData').click();

document.getElementById('Det').click();

  }

})); 

_onPublishClick: function() {

   this.publishData({

     message: document.getElementById('RegNo').value;

});

this.i ++;

},

toOpenWidget: function() {

var widget = this.appConfig.getConfigElementsByName('Details');

var widgetId = widget[0].id;

this.openWidgetById(widgetId).then(lang.hitch(this, function(widget) {

}));

}

In widget.Html i am adding the below.

<button type="button" id="Det" data-dojo-attach-event="click:toOpenWidget" style="display:none;"/> 

<input type="text" id="RegNo" value="" style="display:none;"></input/>

<input type="text" id="publishData" value="Publish Data" style="display:none;" data-dojo-attach-event="_onPublishClick"></input/>

This is working for me . But when i try to add the below statement in Config file the widget is not showing up.

"visible": false

but when i try to open the widget it is not becoming true when i add your code.

Please guide me am missing something.

Kafil,

  Your button click event is out of scope. The scope of "this" is the button click event and not the widget. This is normally a problem when trying to add inline click events to html code. Instead you need to add a click handler programatically so that you can use lang.hitch.

Thanks Robert. The above code worked for me.

I have another query regarding eSearch widget.

I am using eSearch widget when url is passed from other application. The eSearch widget icon is also showed in AnchorController. Where i want to make it visible : false and open the widget only when the Url Param is passed from other application. Where exactly i should place this code to work.

The eSearch widget has to be open at startup in order to receive URL parameters so what I recommended previously will not work.
