[FlowListView] Trying to use it coming from ListView

Hi,

My problem is that I was using ListView but it didn’t accomplish my goals and I seen that the most useful thing would be to use FlowListView. I addapted my code and the GUI don’t show me any kind of data in the implied page. Before that change ListView was showing all data in “factors” and now I can’t see anything.

What I had was:

C# HomeViewModel.cs

using System;
using System.ComponentModel;
using System.Collections.ObjectModel;
using HotelSaver.Models;

namespace HotelSaver.ViewModel
{
    public static class HomeViewModel
    {
        public static ObservableCollection<Factor> factors {
            get;
            set;
        }
        static HomeViewModel()
        {
            HomeViewModel.factors = DataSource.getFactors();
        }
    }
}

XAML HomePage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="HotelSaver.HomePage"
             Title="Inici"
             xmlns:local="clr-namespace:HotelSaver.ViewModel;assembly=HotelSaver">
    <ContentPage.Content>
            <ListView x:Name="FactorsListView" SeparatorVisibility="None" ItemsSource="{x:Static local:HomeViewModel.factors}" ItemSelected="listSelection">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell>
                            <StackLayout Orientation="Horizontal">
                                <Label Text="{Binding name}" HorizontalOptions="CenterAndExpand" FontSize="18" />
                                <Label Text="100%" TextColor="Green" HorizontalOptions="End" />
                            </StackLayout>
                        </ViewCell>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
    </ContentPage.Content>
</ContentPage>

And know I changed the XAML to:

XAML HomePage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="HotelSaver.HomePage"
             Title="Inici"
             xmlns:local="clr-namespace:HotelSaver.ViewModel;assembly=HotelSaver"
             xmlns:flv="clr-namespace:DLToolkit.Forms.Controls;assembly=DLToolkit.Forms.Controls.FlowListView">
    <ContentPage.Content>
            <flv:FlowListView x:Name="FactorsView" FlowColumnCount="3" SeparatorVisibility="None" HasUnevenRows="False" FlowItemsSource="{x:Static local:HomeViewModel.factors}" FlowItemTappedCommand="listSelection">
                <flv:FlowListView.FlowColumnTemplate>
                    <DataTemplate>
                        <Label Text="{Binding name}" HorizontalOptions="CenterAndExpand" XAlign="Center" YAlign="Center" FontSize="18" />
                        <Label Text="100%" TextColor="Green" XAlign="Center" YAlign="Center" HorizontalOptions="CenterAndExpand" />
                    </DataTemplate>
                </flv:FlowListView.FlowColumnTemplate>
    </ContentPage.Content>
</ContentPage>

I don’t know what I’m doing bad. I inserted FlowListView.Init(); in App.xaml.cs and everything needed…

Thank you for your time.

Yes, in HomePage.xaml.cs right before InitializeComponent();

The ViewModel which doesn’t implement INotifyPropertyChanged, static fields, the View without bindings… it’s very unusual schema. I think problem in that

@guiu23 but does it work with <flv:FlowListView.ItemTemplate> ?

loadingcommand not work…
