How could I achieve the following , it is a list of many items. on it
Design Goal
and this is my code :
<Label Text = "Today Appointments :" TextColor = "#2196f3" WidthRequest = "200"
HeightRequest="50" FontSize = "Small" Margin = "13" FontAttributes = "Bold" ></Label >
<ListView HasUnevenRows="True" ItemsSource="{Binding Appoitments}" RowHeight="5" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid RowDefinitions="Auto,Auto,Auto">
<Frame
BorderColor="Gray"
CornerRadius="5"
Padding="8"
HasShadow="True"
>
<StackLayout Orientation="Vertical" Padding="5">
<Label Grid.Row="0" Text="{Binding AppointmentPatientName}" TextColor="Black" FontSize="Small" FontAttributes="Bold" Margin="20" />
<Label Grid.Row="0" Grid.Column="1" Text="{Binding AppointmentDate}" TextColor="Black" FontSize="Small" FontAttributes="Bold" Margin="20" />
</StackLayout>
</Frame>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
A CollectionView offers the option to group your items in the list and create a Header for your group.
Enable IsGrouped property :
<CollectionView IsGrouped="true" />
then add
<CollectionView.GroupHeaderTemplate>
<DataTemplate>
//Your Group Header here...
<Label Text="{Binding AppoitmentsId}"
BackgroundColor="LightGray"
FontSize="Large"
FontAttributes="Bold" />
</DataTemplate>
</CollectionView.GroupHeaderTemplate>

I have got the following xaml code:
<StackLayout Padding="10" x:DataType="model:Light">
<StackLayout HorizontalOptions="FillAndExpand" Grid.Column="0" Grid.Row="1">
<Label Text="{Binding Name}" LineBreakMode="NoWrap" Style="{DynamicResource ListItemTextStyle}" FontSize="24" HorizontalOptions="StartAndExpand" VerticalOptions="StartAndExpand"/>
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" Grid.Column="1" Grid.Row="1" >
<Button Text="{Binding Enabled}" Command="{Binding ToggleLight}" CommandParameter="{Binding .}" HorizontalOptions="CenterAndExpand"></Button>
</StackLayout>
</StackLayout>
How do I exclude Command="{Binding ToggleLight}" on my Button form the x:DataType="model:Light" defined on my StackLayout?
Use binding-path.
Define "x:Name" outside the StackLayout (StackLayout, Grid, ListView and etc.)
Add "x:Reference" for your Command binding inside the StackLayout
The command is excluded.
Like:
<Grid x:Name="WhateverParent">
<StackLayout x:DataType="model:Light">
<Button ... Command="{Binding Path=BindingContext.ToggleLight, Source={x:Reference WhateverParent}}" />
</StackLayout>
</Grid>
How to keep the built-in Header of a ListView frozen to the top when scrolling vertically down through the ListView items?
Before flagging as duplicate: I tried to apply answers in Keep ListView.HeaderTemplate visible/static/sticky in UWP for Xamarin.Forms targeting Android without success.
Short code sample:
<ListView ItemsSource="{Binding MyList}"
HasUnevenRows="True"
SeparatorVisibility="Default"
CachingStrategy="RecycleElement">
<ListView.Header>
<Label HorizontalTextAlignment="Center"
FontAttributes="Bold"
Text="Header Title"/>
</ListView.Header>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Label Text="{Binding Name}"/>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Here is an alternative approach to this if the list isn't long
<StackLayout>
<Label HorizontalTextAlignment="Center"
FontAttributes="Bold"
Text="Header Title"/>
<StackLayout BindableLayout.ItemsSource="{Binding MyList}">
<BindableLayout.ItemTemplate>
<DataTemplate>
<StackLayout>
<Label Text="{Binding Name}"/>
<!-- boxview as separator -->
<BoxView HeightRequest="1" Color="Aqua" HorizontalOptions="FillAndExpand"/>
</StackLayout>
</DataTemplate>
</BindableLayout.ItemTemplate>
</StackLayout>
</StackLayout>
Im making an Android application and Im trying to center right checkbox on all rows in the listview, but I cant do it.
I want do something like this. Thanks

<StackLayout Orientation="Vertical">
<RelativeLayout>
<ListView ItemsSource="{Binding Funcionarios}"
HasUnevenRows="True"
Margin="20"
ItemTapped="ListView_ItemTapped">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Horizontal">
<image:CircleImage Source="{Binding Imagem}" Aspect="AspectFill" WidthRequest="60"
HeightRequest="60" BorderColor="Black" BorderThickness="2">
</image:CircleImage>
<StackLayout Orientation="Vertical">
<Label Text="{Binding Nome}" FontSize="Large"/>
<Label Text="{Binding Zona}"/>
<CheckBox IsChecked="False" />
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</RelativeLayout>
</StackLayout>
Try
<ViewCell>
<StackLayout Orientation="Horizontal">
<image:CircleImage Source="{Binding Imagem}" Aspect="AspectFill" WidthRequest="60" HeightRequest="60" BorderColor="Black" BorderThickness="2"> </image:CircleImage>
<StackLayout Orientation="Vertical">
<Label Text="{Binding Nome}" FontSize="Large"/>
<Label Text="{Binding Zona}"/>
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="End">
<CheckBox IsChecked="False" VerticalOptions="Center"/>
</StackLayout>
</StackLayout>
</ViewCell>
I have implemented a listview and in each item I want to have two labels, in each end horizontally. But in reality it just put the two labels next to eachother left aligned.
I read that maybe this is not possible with a stacklayout, as it doesn't take up more space than needed. (Even tried fill and fillandExpand which didn't help.)
Instead I should use a grid. But I have options on my listview, as grouping, refresh, caching, tapped, which I guess I don't have on a grid?
I would like to succeed with a listview if that is possible. Anyone have some insights to this layout issue?
Here is my xaml code:
<?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="MyApp.Page.ItemsTest">
<ListView x:Name="ItemView"
ItemsSource="{Binding ItemGroup}"
CachingStrategy="RecycleElement"
IsGroupingEnabled="true"
HasUnevenRows="True"
ItemTapped="Handle_ItemTapped">
<ListView.GroupHeaderTemplate>
<DataTemplate>
<ViewCell>
<StackLayout BackgroundColor="#FFA500" Orientation="Vertical" Padding="10">
<StackLayout Orientation="Horizontal">
<Label Text="{Binding Heading}" TextColor="White" FontAttributes="Bold" />
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.GroupHeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Horizontal" Padding="10" HorizontalOptions="FillAndExpand">
<Label Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage>
Central part is this:
<StackLayout Orientation="Horizontal" Padding="10" HorizontalOptions="FillAndExpand">
<Label Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</StackLayout>
Update:
As requested I have a colored the background of the two labels and the stacklayout. It's the same output if I use HorizontalOptions="End" and HorizontalTextAlignment="End" at the same time or each one alone. Also if I remove the HorizontalOptions="FillAndExpand" on the stacklayout, it's still the exact same graphical output. (The orange color was already present)
Maybe you could use a Grid instead of the StackLayout and place each Label in a different Column:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Text="{Binding Name}" FontAttributes="Bold" HorizontalTextAlignment="Start"/>
<Label Grid.Column="1" Text="{Binding Start, StringFormat='{0:HH:mm}'}" FontAttributes="Bold" HorizontalTextAlignment="End"/>
</Grid>
You could also use nested StackLayout
<StackLayout>
<Label />
<Label Text="Gender:" FontAttributes="Bold"/>
<StackLayout Orientation="Horizontal">
<Label HorizontalOptions="Start" Text="First Name: " FontAttributes="Bold"/>
<Entry HorizontalOptions="EndAndExpand" Placeholder="First Name" MaxLength="256" Text="{Binding FirstName}"></Entry>
</StackLayout>
</StackLayout>
I am with a problem. I have a imagecell inside of a Listview, inside of a Frame and i put all inside a stacklayout.
My problem is that the height of the frame with the imagecell are too expensive. Now, i just have 2 items inside but the height is like the size of the page.
The XAML code:
<AbsoluteLayout HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<StackLayout AbsoluteLayout.LayoutFlags="All" AbsoluteLayout.LayoutBounds="0,0,1,1">
<ScrollView>
<StackLayout Padding="10,20,10,10">
<Frame x:Name="frameOpcoes" OutlineColor="Gray" HasShadow="True" VerticalOptions="Fill" HorizontalOptions="FillAndExpand" BackgroundColor="White">
<StackLayout Padding="0,10,0,0" Orientation="Vertical">
<StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand">
<StackLayout Orientation="Vertical" HorizontalOptions="Start">
<Label x:Name="lblOpcoes" Text="Placa: " TextColor="Gray" FontAttributes="Bold"/>
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand">
<Entry x:Name="entryPlacaLetra" TextChanged="entryLetra_TextoAlterado" Keyboard="Text" TextColor="Black" BackgroundColor="#D3D3D3" />
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="Fill">
<Label x:Name="lblTraco" Text="-" TextColor="Gray" FontAttributes="Bold"/>
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand">
<Entry x:Name="entryPlacaNum" TextChanged="entryNum_textoAlterado" Keyboard="Numeric" TextColor="Black" BackgroundColor="#D3D3D3"/>
</StackLayout>
</StackLayout>
<StackLayout VerticalOptions="FillAndExpand">
<ListView x:Name="listView" HorizontalOptions="FillAndExpand" VerticalOptions="Start" HasUnevenRows="True" SeparatorVisibility="None">
<ListView.ItemTemplate>
<DataTemplate >
<ImageCell Text="{Binding Title}" Detail="{Binding Detail}" DetailColor="Gray" TextColor="Black" ImageSource="{Binding IconSource}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</StackLayout>
</Frame>
<StackLayout Padding="0,30,0,0" x:Name="stckCalculo" VerticalOptions="EndAndExpand">
<Button x:Name="btnCalcular" BorderColor="Silver" BackgroundColor="Red" TextColor="White" Text="Prosseguir" />
</StackLayout>
</StackLayout>
</ScrollView>
</StackLayout>
<StackLayout IsVisible="{Binding IsBusy}" Padding="12"
AbsoluteLayout.LayoutFlags="PositionProportional"
AbsoluteLayout.LayoutBounds="0.5,0.5,-1,-1">
<Frame Padding="50" OutlineColor="Black" HasShadow="true" AbsoluteLayout.LayoutFlags="PositionProportional" Opacity="0.8" BackgroundColor="Black" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand">
<ActivityIndicator IsRunning="{Binding IsBusy}" Color ="White"/>
<Label Text="Aguarde..." HorizontalOptions="Center" TextColor="White"/>
</Frame>
</StackLayout>
</AbsoluteLayout>
You can create a custom cell like this
<ListView x:Name="listView">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Horizontal">
<Image Source="{Binding image}" />
<Label Text="{Binding title}"
TextColor="#f35e20" />
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
