How to Switch to a Different Tab in a NativeScript TabView

I'm struggling to figure out how to programmatically navigate to a different tab within a tabView from a partial View. Each tab is located in a child folder with its own html, ts, js, and css files. In this scenario, when a user clicks on an item in a list, I want it to switch to another tab while passing along the context (item data).

In the parent file, I can change the selected tab using the following code snippet:

export function nav()
{
    pageData.set("tabIndex", 2);
}

However, I'm unsure of how to achieve this from a child document or how to pass data to a different partial view.

I'm using partial views to create the tabs, with each partial view being stacklayouts. Therefore, my page with the tab-view is structured as follows:

<TabView selectedIndex="{{tabIndex}}" >
 <TabView.items>
  <TabViewItem title="Drop Sequence">
    <TabViewItem.view>
      <DropSequence:DropSequence />
    </TabViewItem.view>
  </TabViewItem>

  <TabViewItem title="Edit Order" >
    <TabViewItem.view>
      <EditOrder:EditOrder />
    </TabViewItem.view>
  </TabViewItem>

My typical approach involves using NativeScript-Angular, which I interpret as taking advantage of Angular functionality.

To begin, assign an id to the TabView element such as id="tabview1" and then proceed with the following code snippet:

let tabview1 = page.getViewById("tabview1");
tabview1.selectedIndex = 1;
