I use #if in Svlte Native but it doesn't work - nativescript

I try out Svelte Native and I try to hide "tags" with booleans. I try this, which works in the normal Svelte framework like:
{#if po.id !== null || po.id !== undefined}
<flexboxLayout flexWrap="wrap" class="v-a-c t-a-c" >
<label text="first" width="70%" backgroundColor="#63c3d0" class="m6"></label>
<label text="second" width="70%" backgroundColor="#63c3d0" class="m6"></label>
<label text="third" width="70%" backgroundColor="#63c3d0" class="m6"></label>
</flexboxLayout>
{:else }
<stackLayout flexWrap="wrap" class="v-a-c t-a-c">
<textField bind:text="{personName}" class="m6 new-person" ></textField>
<button text="add new value" on:tap="{createNewPlayer}" />
</stackLayout>
{/if}
So why it doesn't work? What am I doing wrong?

Nativescript Vue: Why does position of code matter in a Dock Layout matter?

Why does this following code produce this result: https://imgur.com/a/lQhLs8o ?
However, if I move the BottomNavigatorBar component to top position before CountryListComponent, it produces the desired result that looks like this: https://imgur.com/a/23z7bb2 ?
<template>
<Page actionBarHidden="true">
<DockLayout height="100%">
// first
<CountryListComponent dock="top">
// second
<BottomNavigationBar dock="bottom" activeColor="pink"
inactiveColor="yellow"
backgroundColor="black"
verticalAlignment="bottom"
#tabSelected="this.changeTab"
row="1">
<BottomNavigationTab title="Fiaarst" icon="icon-29.png" />
<BottomNavigationTab title="Second" icon="icon-29.png" />
<BottomNavigationTab title="Third" icon="icon-29.png" />
</BottomNavigationBar>
</DockLayout>
</Page>
</template>
CountryListComponent
<template>
<StackLayout backgroundColor="blue">
</StackLayout>
</template>
Refer the DockLayout documentation, by default stretchLastChild will be true which means BottomNavigationBar will take entire space if it's last child and vice versa.

how can i create multiline editable textview in nativescript?

i try beloved code but dos't work in android can't get new line
<TextView style="margin-top: 15px" borderColor="#DEDEDE" borderWidth="1"
height="100px" hint="Enter Note" returnKeyType="send" class="input input-border"></TextView>
<Button text="ADD" (tap)="insertNote()"></Button>
Use height attribute without 'px' unit like this :
<TextView style="margin-top: 15px" borderColor="#DEDEDE" borderWidth="1" height="100" hint="Enter Note" returnKeyType="send" class="input input-border"/>
Or give greater value for height in pixel : 200px

How to use telerik ui plug in for side drawer in NativeScript app

I'm using Telerik UI plugin in my NativeScript app for implementing drawer functionality.I'm following this tutorial for this - https://www.nativescript.org/blog/details/using-cross-platform-native-sidedrawer-component-in-nativescript
Here is my Code-
import {Component} from "#angular/core";
import listViewModule = require("nativescript-telerik-ui/listview");
import drawerModule = require("nativescript-telerik-ui/sidedrawer");
#Component({
selector: "my-app",
template: `
<drawer:SideDrawer id="drawer1">
<drawer:SideDrawer.mainContent>
<!-- Place your page content here -->
<StackLayout>
<Label text="Tap the button" class="title"></Label>
<Button text="TAP" (tap)="onTap()"></Button>
<Label [text]="message" class="message" textWrap="true"></Label>
</StackLayout>
<StackLayout>
<Button tap="openDrawer" text="ToggleDrawer"/>
</StackLayout>
</drawer:SideDrawer.mainContent>
<drawer:SideDrawer.drawerContent>
<StackLayout cssClass="drawerContent">
<StackLayout cssClass="headerContent">
<Label text="Drawer Header"/>
</StackLayout>
<StackLayout cssClass="drawerMenuContent">
<Label text="Item 1"/>
<Label text="Item 2"/>
<Label text="Item 3"/>
<Label text="Item 4"/>
</StackLayout>
</StackLayout>
</drawer:SideDrawer.drawerContent>
</drawer:SideDrawer>
`,
})
export class AppComponent {
public counter: number = 16;
public get message(): string {
if (this.counter > 0) {
return this.counter + " taps left";
} else {
return "Hoorraaay! \nYou are ready to start building!";
}
}
public onTap() {
this.counter--;
}
}
When I'm running this in my Emulator I'm getting a blank page. I'm using AngularJS2 with typescript & totally new to both these tools. So, can't able to understand what's I'm doing wrong.
Need some Guide.
nativescript-telerik-ui\listview and sidedrawer was before 2.0.0-rc.1 so they are currently working on it you can check this link - https://github.com/telerik/nativescript-ui-samples-angular/issues/1#issuecomment-225791969
if you are using beta version of angular then check this link to repository - https://github.com/telerik/nativescript-ui-samples-angular/tree/release/sdkAngular/app/sidedrawer

titanium alloy onClick parameters

first of all: I am practicing with titanium, this are just my first "Hello World" apps to get confident with the framework, so any suggestion would be strongly appreciated.
I have this simple view:
<ScrollView id="grid" dataCollection="pictures">
<View class="single-item" title="{title}" author="{author}" desc="{desc}" onClick="showPic">
<ImageView class="thumb" image="/images/thumb-stock-1.jpg" />
<Label class="title" text="{title} by {author}" />
<Label class="desc" text="{desc}" />
</View>
</ScrollView>
Clicking on each item I call the function showPic() defined in my controller, and that's ok. But I would like to pass some parameters to that function, that are {title}, {author} and {desc}, so that I can handle them and "print" them on a new detail view for each specific item. With TableView it was easy (I just put: event.source -> title, event.source -> author ... inside my controller and I could read that table row data), but with my view that seems not work.
so my questions are:
1) how can I pass that parameters from VIEW: to CONTROLLER showPic()
2) generally speaking, if there is a better view to list some objects and opening each one with a click, just tell me how so that I can learn something more :D (PS: I cannot use tableView because my layout does not fit with this kind view)
---- EDIT: here follows my full code
index.xml:
<Alloy>
<Collection src="pictures"/>
<NavigationWindow id="navGroupWin">
<Window class="container" title="La mia galleria">
<View class="arrow arrow-up"><Label text="UP" /></View>
<ScrollView id="grid" dataCollection="pictures">
<View class="single-item" title="{title}" author="{author}" desc="{desc}" onClick="showPic">
<ImageView class="thumb" image="/images/thumb-stock-1.jpg" />
<Label class="title" text="{title} by {author}" />
<Label class="desc" text="{desc}" />
</View>
</ScrollView>
<View class="arrow arrow-down"><Label text="DOWN" /></View>
</Window>
</NavigationWindow>
</Alloy>
showPic from index.js:
function showPic(event) {
var pic = event.source;
var args = {
title: pic.title,
desc: pic.desc,
author: pic.author
};
var picView = Alloy.createController("detail", args).getView();
if (OS_IOS) {$.navGroupWin.openWindow(picView);}
if (OS_ANDROID) {picView.open();}
}
detail.xml:
<Alloy>
<Window class="container">
<View layout='vertical'>
<Label id="titleLabel"></Label>
<Label id="descLabel"></Label>
<Label id="authorLabel"></Label>
</View>
</Window>
</Alloy>
detail.js
var args = arguments[0] || {};
$.titleLabel.text = args.title || 'Default Title';
$.descLabel.text = args.desc || 'Default desc';
$.authorLabel.text = args.author || 'Default author';
when I click on each item of the index, my source.title, source.author and source.desc seems to be empty, and on the detail window I got back only 'Default' values
I am not sure if you can do this on the view file level.
What I would try is to assign ids to every view element (this is a general technique) and fully deploy all my click listeners inside the controller file, removing all onClick commands from view.
So:
Set id="myview" along with class="single-item" in your View
In your controller try
$.myview.addEventListener('click', function(e){
showPic(e.title, e.author, e.desc)
});
Not sure if it goes wrong somewhere else, but stripped down like this it works:
index.html
<Alloy>
<Window id="test">
<ScrollView id="grid" layout="vertical">
<View class="single-item" width="250" height="250" backgroundColor="blue" title="title" author="author" desc="desc" onClick="showPic">
</View>
<View class="single-item" width="250" height="250" backgroundColor="red" title="red" author="red" desc="red" onClick="showPic">
</View>
<View class="single-item" width="250" height="250" backgroundColor="yellow" title="yellow" author="yellow" desc="yellow" onClick="showPic">
</View>
<View class="single-item" width="250" height="250" backgroundColor="green" title="green" author="green" desc="green" onClick="showPic">
</View>
</ScrollView>
</Window>
</Alloy>
index.js
function showPic(event) {
Ti.API.info(JSON.stringify(event.source));
}
$.test.open();
