Hi All,

as per our requirement we will be performing some operations in both widget A and widget B.

after that when we click on clear button in widget B then widget A needs to close and get destroy so that performed operations on widget A needs to get cleared. 

 

Kindly do the needful

 

Thanks.

@naveenbesri You can close a widget using this line of code.

this.props.dispatch(appActions.closeWidget("the ID of the widget you want to close"));

Not sure about how to destroy a widget or why you would want to verses just close the widget. In widget widget A you can add some code to componentDidUpdate to do any clean up of things you did in widget A, like outlined in this thread. https://community.esri.com/t5/arcgis-experience-builder-questions/widget-close-event/m-p/1040201#M16...

@naveenbesri  So for the onScreen widget placeholder to not be visible but be loaded and listening for another widget that is pretty simple. In the aps main config.json just search for the widgets name and make the widgets position left attribute a large negative number.

"position": {
  "left": -550,

@naveenbesri Here is some code I use to open an off screen widget.

define([
...
'jimu/WidgetManager',
    'jimu/PanelManager',
    'dojo/_base/array',
  ],
function (
...
WidgetManager, PanelManager, array
  ) {
...

postCreate: function () {
...
this.wManager = WidgetManager.getInstance();
        this.pManager = PanelManager.getInstance();
      },

_openAboutWidget: function () {
        if (this.wManager) {
          var widgetCfg = this._getWidgetConfig('About');
          if (widgetCfg) {
            var aboutWidget = this.wManager.getWidgetByLabel(widgetCfg.label);
            if (aboutWidget) {
              this.wManager.openWidget(aboutWidget);
              this.pManager.showPanel(aboutWidget);
            } else {
              this.wManager.loadWidget(widgetCfg).then(lang.hitch(this, function (widget) {
                if (widget) {
                  this.wManager.openWidget(widget);
                  this.pManager.showPanel(widgetCfg).then(lang.hitch(this, function (panel) {
//Move the widgets position back to on screen
                    panel.setPosition({
                      top: 45,
                      left: 55
                    });
                    this.pManager.normalizePanel(panel);
                  }))
                }
              }));
            }
          }
        }
      },

      _getWidgetConfig: function(widgetName) {
        var widgetCnfg = null;
        array.some(this.wManager.appConfig.widgetPool.widgets, function(aWidget) {

            return true;
          }
          return false;
        });
        if(!widgetCnfg) {
          /*Check OnScreen widgets if not found in widgetPool*/
          array.some(this.wManager.appConfig.widgetOnScreen.widgets, function(aWidget) {
            if(aWidget.name == widgetName) {
              widgetCnfg = aWidget;
              return true;
            }
            return false;
          });
        }

@naveenbesri Sorry I forgot to check which forum I was in. Is widget B an onScreenWidget or is it part of the HeaderControllers' widgets? The answer to that will make all the difference in the code that I will share.

Hi Robert, widget B is an onScreen widget and widget B icon shouldn't  be visible in application but it has to open while sending data to widget b from widget A.
