nativescript data has to be displayed grid view with 4*4 - nativescript

For displaying the grid view (4*4) in nativescript with Angular, I have integrated the npm "nativescript-grid-view" as per the example in npm site. But, It fails for me. I got the error whenever I enter that page in the application.
Error :
System.err: Error: Expecting a valid View instance.
System.err: File: "file:///data/data/com.domain.project/files/app/tns_modules/tns-core-modules/ui/core/view-base/view-base.js, line: 337, column: 12

Or you could use nativescript-ui-listview and its ListViewGridLayout with spanCount property. The official documentation for this functionality is here. Basically, you could do the following:
<RadListView [items]="dataItems">
<ng-template tkListItemTemplate let-item="item">
<!-- item template here -->
</ng-template>
<ListViewGridLayout tkListViewLayout spanCount="4" scrollDirection="Vertical" ios:itemHeight="200" ></ListViewGridLayout>
</RadListView>

NativeScript 4X4 GridLayout
I have written some code in the nativescript playground link.
**
https://play.nativescript.org/?template=play-ng&id=a8UEDd

<GridLayout rows="*,*,*,*" columns="*,*,*,*">
<Label text="1" row="0" col="0" borderColor="black" borderWidth="1"></Label>
<Label text="2" row="0" col="1" borderColor="black" borderWidth="1"></Label>
<Label text="3" row="0" col="2" borderColor="black" borderWidth="1"></Label>
<Label text="4" row="0" col="3" borderColor="black" borderWidth="1"></Label>
<Label text="5" row="1" col="0" borderColor="black" borderWidth="1"></Label>
<Label text="6" row="1" col="1" borderColor="black" borderWidth="1"></Label>
<Label text="7" row="1" col="2" borderColor="black" borderWidth="1"></Label>
<Label text="8" row="1" col="3" borderColor="black" borderWidth="1"></Label>
<Label text="9" row="2" col="0" borderColor="black" borderWidth="1"></Label>
<Label text="10" row="2" col="1" borderColor="black" borderWidth="1"></Label>
<Label text="11" row="2" col="2" borderColor="black" borderWidth="1"></Label>
<Label text="12" row="2" col="3" borderColor="black" borderWidth="1"></Label>
<Label text="13" row="3" col="0" borderColor="black" borderWidth="1"></Label>
<Label text="14" row="3" col="1" borderColor="black" borderWidth="1"></Label>
<Label text="15" row="3" col="2" borderColor="black" borderWidth="1"></Label>
<Label text="16" row="3" col="3" borderColor="black" borderWidth="1"></Label>
</GridLayout>
Preview of the 4x4 GridLayout will be like this

Below code does work without using nativeoscript-grid-view. I think that nativescript version is the problem.
<ScrollView class="plansScroll" #plansScroll orientation="vertical" horizontalAlignment="center" width="100%">
<WrapLayout orientation="horizontal" [id]="myIndex" (tap)="onPlanSectionTap($event)" class="plansScrollGrid m-5" #plansScrollGrid>
<StackLayout *ngFor='let item of order; let myIndex = index' width="25%">
<!-- <Image [src]="item.imagePath" width="80"></Image> -->
<Image width="80" [src]="'~/assets/img/bratShop-overlay.jpg'"></Image>
<Label [text]='item.productName' textWrap="true" horizontalAlignment="center" verticalAlignment="center" #plansScrollGridType></Label>
<Label [text]='item.orderNumber' textWrap="true" horizontalAlignment="center" verticalAlignment="center" #plansScrollGridType></Label>
<Label [text]='item.orderStatus' textWrap="true" horizontalAlignment="center" verticalAlignment="center" #plansScrollGridType></Label>
<Label [text]='item.orderDate' textWrap="true" horizontalAlignment="center" verticalAlignment="center" #plansScrollGridType></Label>
</StackLayout>
</WrapLayout>

Nativescript - data not binding onTap

At certain point on my xml file i have this:
<GridLayout row="2" rowSpan="2" col="2" rows="*" columns="40,*,40" verticalAlignment="center" horizontalAlignment="right" marginRight="10">
<Label row="0" col="0" text="+" tap="onTapPlus" verticalAlignment="center" horizontalAlignment="center" style="color:black;font-family: 'Allerta Stencil', sans-serif;font-size:20px;"></Label>
<Label id="" row="0" col="1" text="{{nrItemsTakeAway}}" verticalAlignment="center" horizontalAlignment="center" style="color:black;font-family: 'Allerta Stencil', sans-serif;font-size:20px;text-align:center; width:50px;"></Label>
<Label row="0" col="2" text="-" tap="onTapMinus" verticalAlignment="center" horizontalAlignment="center" style="color:black;font-family: 'Allerta Stencil', sans-serif;font-size:20px;"></Label>
</GridLayout>
So when the user taps on the + button, the onTapPlus function is called and the nrItemsTakeAway is suppose to increment...so just for testing, i did this on my onTapPlus function:
function onTapPlus(args) {
const button = args.object;
const page = button.page;
vm.set("nrItemsTakeAway", "4");
page.bindingContext = vm;
but it doesn´t work...it is not binding, what am i missing here?

Nativescript inner StackLayout

Hello everyone I'm trying to make inner StackLayouts but the second one comes to top of first one so that I can't see the second StackLayout should I handle with css if it is how or is there an other way
Here is my code
<StackLayout orientation="horizontal">
<StackLayout width="500">
<GridLayout columns="50, *" rows="*" width="500" height="50"
verticalAlignment="top">
<Label text="Name" row="0" col="0" backgroundColor="red">
</Label>
<Label text="Fol" row="0" col="1" class="alignRight"
backgroundColor="blue"></Label>
</GridLayout>
</StackLayout>
<StackLayout orientation="horizontal" width="500" height="180">
<Image src="http://lorempixel.com/400/200" width="500" left="10"
top="30">
</Image>
</StackLayout>
</StackLayout>
Thank you
At first I would delete the widths to see how the page is displayed. 500 is a very big value. Only large tablets can support that.
As an example at first I would try this :
<GridLayout columns="auto, auto">
<GridLayout col="0" columns="50, *" rows="*" verticalAlignment="top">
<Label text="Name" row="0" col="0" backgroundColor="red">
</Label>
<Label text="Fol" row="0" col="1" class="alignRight"
backgroundColor="blue"></Label>
</GridLayout>
<Image col="1" src="http://lorempixel.com/400/200" left="10" op="30">
</Image>
</GridLayout>
After you see the two parts align horizontally you can start tweaking the widths

How can I make a StackLayout with ngFor loop into scrollable list?

<StackLayout width="100%" *ngFor="let item of (videos$ | async)">
<CardView class="studentCard" margin="2" elevation="10" radius="1">
<GridLayout rows="auto, auto, auto" columns="auto, auto, *">
<Image [src]="item.snippet.thumbnails.high.url" stretch="aspectFill" colSpan="3" row="0"></Image>
<Label [text]="item.snippet.channelTitle" textWrap="true" row="2" colSpan="1" ></Label>
<Label [text]="item.snippet.title" textWrap="true" row="2" col="1" colSpan="2" >></Label>
</GridLayout>
</CardView>
</StackLayout>
I tried to wrap it in ScrollView, didn't work.
I couldn't make (items$ | async) work with ListView either, seems ngFor can't work with ListView, we need ng-template for ListView.
I tried the following but only the first item is rendering
<ScrollView>
<ListView [items]="videos$ | async" class="list-group">
<ng-template let-item="item">
<GridLayout class="list-group-item">
<Image [src]="item.snippet.thumbnails.high.url"></Image>
<Label [text]="item.snippet.channelTitle" ></Label>
<Label [text]="item.snippet.title">></Label>
</GridLayout>
</ng-template>
</ListView>
</ScrollView>
Wraping the entire code first with StackLayout then with ScrollView worked
<ScrollView>
<StackLayout>
<StackLayout width="100%" *ngFor="let item of (videos$ | async)">
<CardView class="studentCard" margin="2" elevation="10" radius="1">
<GridLayout rows="auto, auto, auto" columns="auto, auto, *">
<Image [src]="item.snippet.thumbnails.high.url" stretch="aspectFill" colSpan="3" row="0"></Image>
<Label [text]="item.snippet.channelTitle" textWrap="true" row="2" colSpan="1" ></Label>
<Label [text]="item.snippet.title" textWrap="true" row="2" col="1" colSpan="2" >></Label>
</GridLayout>
</CardView>
</StackLayout>
</StackLayout>
</ScrollView>

Very strange behaviour when trying to replicate a table using a Listview and GridLayout

I am trying to replicate a table using a ListView. Displaying the table's cell content works fine but when I add another GridLayout wrapped in a StackLayout above the Listview the Listview doesn't get displayed at all... Any idea why this might be happening? I tried as well to add the table headers to the ListView using nsTemplateKey but still get the same issue where the headers show but no table body content. When I remove the top GridLayout containing the headers the Listview's content displays perfectly as it should for some reason...
my code:
//headers
<StackLayout class="m-b-10">
<GridLayout rows="*" columns="*, *, *" *ngIf="stockTakeDetailList.length > 0 && !product">
<Label row="0" col="0" text="Name"></Label>
<Label row="0" col="1" text="Qty"></Label>
<Label row="0" col="2" text="Action"></Label>
</GridLayout>
</StackLayout>
//listview containing the table body
<StackLayout *ngIf="stockTakeDetailList.length > 0 && !product">
<ListView [items]="stockTakeDetailList">
<template let-captureItem="item" let-i="index">
<GridLayout rows="*" columns="*, *, *">
<Label row="0" col="0" class="list-group-item" textWrap="true" [text]="captureItem.ProductDetail_Name"></Label>
<Label row="0" col="1" class="list-group-item" [text]="captureItem.Qty"></Label>
<Label row="0" col="2" class="list-group-item font-awesome" text="" (tap)="removeCaptureItem(i)"></Label>
</GridLayout>
</template>
</ListView>
</StackLayout>
Try encapsulating all of the code within a StackLayout:
<StackLayout>
<StackLayout class="m-b-10">
<GridLayout rows="*" columns="*, *, *" *ngIf="stockTakeDetailList.length > 0 && !product">
<Label row="0" col="0" text="Name"></Label>
<Label row="0" col="1" text="Qty"></Label>
<Label row="0" col="2" text="Action"></Label>
</GridLayout>
</StackLayout>
<StackLayout *ngIf="stockTakeDetailList.length > 0 && !product">
<ListView [items]="stockTakeDetailList">
<template let-captureItem="item" let-i="index">
<GridLayout rows="*" columns="*, *, *">
<Label row="0" col="0" class="list-group-item" textWrap="true" [text]="captureItem.ProductDetail_Name"></Label>
<Label row="0" col="1" class="list-group-item" [text]="captureItem.Qty"></Label>
<Label row="0" col="2" class="list-group-item font-awesome" text="" (tap)="removeCaptureItem(i)"></Label>
</GridLayout>
</template>
</ListView>
</StackLayout>
</StackLayout>
Maybe try without the extra stack layouts:
<StackLayout>
<StackLayout class="m-b-10">
<GridLayout rows="*" columns="*, *, *" *ngIf="stockTakeDetailList.length > 0 && !product">
<Label row="0" col="0" text="Name"></Label>
<Label row="0" col="1" text="Qty"></Label>
<Label row="0" col="2" text="Action"></Label>
</GridLayout>
</StackLayout>
<ListView [items]="stockTakeDetailList" *ngIf="stockTakeDetailList.length > 0 && !product">
<template let-captureItem="item" let-i="index">
<GridLayout rows="*" columns="*, *, *">
<Label row="0" col="0" class="list-group-item" textWrap="true" [text]="captureItem.ProductDetail_Name"></Label>
<Label row="0" col="1" class="list-group-item" [text]="captureItem.Qty"></Label>
<Label row="0" col="2" class="list-group-item font-awesome" text="" (tap)="removeCaptureItem(i)"></Label>
</GridLayout>
</template>
</ListView>
</StackLayout>
