  Hi Wijmo team,
  
  How can I retain the selected items of the wj-list-box items on navigating to a different route ( selecting the items and generating the report )? when I close the report view the multi-select view should have all the previous selections.
  
  I have created a shareable service and stored the selected items in an object by calling the (checkedItemsChange)="CheckItemIds($event,businessSegs,bsListBox).
  
  When I come back from the report view I do get the selected item data from the service as below

  t._rs.GetWijmoListBoxData$.subscribe((data: object) => {
              t.wijmoListBoxData = data;
          });
  

  inside the ```
  
  public CheckItemIds(e: any, controlName, listBox: WjListBox) { }

  and then patching the value to a FormGroup. 
  
  Please help

  Hi,
  
  You should place Control for the main component instead of Routed component (Where router-outlet directive is placed). Or you can store selected values and assign back on view change.
