I added ContentView xaml file in xamarin.forms project, but it showing annoying warning
The property 'Content' is set more than once.
Below my ContentView.xaml file
<ContentView
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="XamarinTestList.View.AddContect">>

Maybe because your ContentView has two '>' at the end?

I'm creating an app using MAUI and I'm trying to make it so an ImageButton and SearchBar nested in a VerticalStackLayout move positioning based on the dynamically created CollectionView.
This is the code for the UI:
<Grid>
<FlexLayout VerticalOptions="Center" HorizontalOptions="Center">
<StackLayout>
<CollectionView x:Name="taskList">
<CollectionView.ItemTemplate>
<DataTemplate x:DataType="models:Task">
<VerticalStackLayout Margin="15">
<Entry Text="{Binding name}" IsReadOnly="True" />
<Entry Text="{Binding departmentsString}" IsReadOnly="True"/>
<HorizontalStackLayout>
<Entry Text="{Binding status}" IsReadOnly="True"/>
<Entry Text="{Binding deadline}" IsReadOnly="True" />
<Entry Text="{Binding author.fullName}" IsReadOnly="True"/>
</HorizontalStackLayout>
<Entry Text="{Binding description}" IsReadOnly="True" />
</VerticalStackLayout>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</StackLayout>
<VerticalStackLayout Margin="15">
<Entry Placeholder="Name" x:Name="nameTxt"/>
<Entry Placeholder="Department" x:Name="departTxt"/>
<HorizontalStackLayout>
<inputs:SfComboBox x:Name="statusTxt" Placeholder="Status" BackgroundColor="Black" TextColor="Green" DropDownIconColor="Green"/>
<Entry Placeholder="deadline" x:Name="deadlineTxt"/>
<Entry Placeholder="Author" x:Name="authorTxt"/>
</HorizontalStackLayout>
<Entry Placeholder="Description" x:Name="descTxt"/>
</VerticalStackLayout>
</FlexLayout>
<VerticalStackLayout VerticalOptions="Center" >
<SearchBar Placeholder="Search" x:Name="searchBar" TextChanged="searchBar_TextChanged" MaxLength="30" MaximumWidthRequest="200"/>
<ImageButton Aspect="AspectFill" x:Name="addBtn" Source="plus.png" BackgroundColor="Black" Clicked="addBtn_Clicked" HeightRequest="64" WidthRequest="64"/>
</VerticalStackLayout>
</Grid>
I have tried every different type of Layout but nothing works.
What should I do?
Needed same design of the form. My coding is this Xamarin form, Xamarin iOS, Android
<Frame Grid.Row="0" Grid.Column="0">
<Image
HeightRequest="50"
Source="Dash01.png"
WidthRequest="50" />
<Label Text="Cow Milk"/>
</Frame>
<BoxView
HeightRequest="3"
HorizontalOptions="Fill"
VerticalOptions="Start"
Color="DimGray" Grid.Row="1" Grid.Column="0" />
Try this Code
<StackLayout
Padding="0,10"
BackgroundColor="#e8f5e4"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand">
<CollectionView
x:Name="foodList"
Grid.Row="1"
Margin="12,0"
HorizontalOptions="FillAndExpand"
ItemSizingStrategy="MeasureAllItems"
SelectionMode="Single"
VerticalOptions="FillAndExpand">
<CollectionView.ItemsLayout>
<GridItemsLayout
HorizontalItemSpacing="5"
Orientation="Vertical"
Span="2"
VerticalItemSpacing="5" />
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
<DataTemplate>
<Frame
Margin="5"
Padding="0"
BackgroundColor="Pink"
CornerRadius="10"
HorizontalOptions="FillAndExpand"
VerticalOptions="Fill">
<StackLayout
Margin="0,0,0,10"
Padding="10"
BackgroundColor="White"
HorizontalOptions="FillAndExpand"
VerticalOptions="Fill">
<Image
Aspect="AspectFit"
HeightRequest="50"
HorizontalOptions="Center"
Source="star.png" />
<Label
FontSize="18"
HorizontalOptions="Center"
HorizontalTextAlignment="Center"
Text="{Binding}" />
</StackLayout>
</Frame>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</StackLayout>
I'm building a CrossPlatform App in Xamarin!
I'm getting data from Web Api and it's working fine, the problem is that the data is showing in ListView like columns but I wanted to display that data in Cells View so I can add functionalities like left and right swipeand I don't know how to do this.
My current XAML UI:
<?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="LastTry.Attendance">
<ListView x:Name="selectOrd" RowHeight="50" SeparatorColor="White"
HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell >
<StackLayout Orientation="Horizontal" >
<StackLayout Orientation="Horizontal" VerticalOptions="Center">
<Label Text="{Binding id}" Font="9" TextColor="Black" />
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" x:Name="employee_name" VerticalOptions="Center" >
<Label Text="{Binding employee_name}" Font="9" TextColor="Black" FontAttributes="Bold" HorizontalTextAlignment="Center"/>
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" x:Name="employee_salary" VerticalOptions="Center" >
<Label Text="{Binding employee_salary}" Font="9" TextColor="Black" FontAttributes="Bold" HorizontalTextAlignment="Center"/>
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" x:Name="employee_age" VerticalOptions="Center" >
<Label Text="{Binding employee_age}" Font="9" TextColor="Black" FontAttributes="Bold" HorizontalTextAlignment="Center"/>
</StackLayout>
<StackLayout HorizontalOptions="FillAndExpand" x:Name="profile_image" VerticalOptions="Center" >
<Label Text="{Binding profile_image}" Font="9" TextColor="Black" FontAttributes="Bold" HorizontalTextAlignment="Center"/>
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage>
Here is an example how I want it:
Here is the code for the listview same as above:
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="MSPL.Views.HomePage">
<AbsoluteLayout>
<ListView x:Name="Demolist" BackgroundColor="White" ItemSelected="Demolist_ItemSelected">
<ListView.ItemTemplate>
<DataTemplate>
<ImageCell Height="30"
Text="{Binding employee_name }"
Detail="{Binding employee_age}"
ImageSource="falto.png">
<ImageCell.ContextActions>
<MenuItem x:Name="OnMore" Clicked="OnMore_Clicked" CommandParameter="{Binding .}" Text="More" />
<MenuItem x:Name="OnDelete" Clicked="OnDelete_Clicked" CommandParameter="{Binding .}" Text="Delete" IsDestructive="True" />
</ImageCell.ContextActions>
</ImageCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ImageButton Source="images.png"
BackgroundColor="Transparent"
AbsoluteLayout.LayoutFlags="PositionProportional"
AbsoluteLayout.LayoutBounds=".95,.95,55,55"
Clicked="ImageButton_Clicked"
/>
</AbsoluteLayout>
So I got this code that I need to re-use on more or less all my pages, but I'm getting kinda tired of changing one page and having to do the same thing in 10 or more places, are there any better way to do this?
Using Xamarin.Forms. Maybe it is possible to do this with a custom controller or some other way with markup extension to inside a stacklayout do a x:static reference to it?

You can create a CustomView and then include that in your Pages.
In order to Achieve that, you create a a YourCustomView.xaml,
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="YourProject.YourCustomView">
</ContentView>
And, in your Page.xaml you include it
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:views="clr-namespace:YourProject;assembly=YourProject"
x:Class="YourProject.YourPage">
<views:YourCustomView/>
</ContentPage>
The next step is about Binding the properties that you need, for that, you need to create BindableProperties in your CustomView. You can reuse this in all pages that you want.
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>
