I am currently working on a UI for an application and I want to align the following label Text automatically horizontally, so I wanted to test, how I can align text normally.
The Label Documentation of Maui state, that I have to do it with the HorizontalTextAlignment Element. I tried it several times and it worked, but here it won't:
<CollectionView Grid.Row="1" BackgroundColor="Black">
<CollectionView.ItemsSource>
<x:Array Type="{x:Type models:MessageModel}">
<models:MessageModel Message="Hallo" Created="01.01.2001 00:00:00"/>
<models:MessageModel Message="Hey na!" Created="01.01.2001 00:00:00"/>
</x:Array>
</CollectionView.ItemsSource>
<CollectionView.ItemTemplate>
<DataTemplate x:DataType="models:MessageModel">
<Label HorizontalTextAlignment="End" TextColor="White" Text="{Binding Created}"/>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
The Output is the following (And yeah I could use one Label, but I wanted to try both ways):
Edit: adding the following Element HorizontalOptions="FillAndExpand" at the label + a Background Color:

My app contains a Flexlayout inside a scrollview. This flexlayout is used as a bindablelayout and contains some items. When there are enough items to fill the screen the vertical itemspacing is nicely done:
However, if the list gets smaller, and less items are visible, the vertical spacing becomes weird (I suspect the items want to fill out the whole available space, but I'm not sure of that):
I want the items to always have the same space between rows. Is this possible?
Xaml:
<ScrollView Margin="10" Grid.Row="1" x:Name="UserActionScrollView">
<FlexLayout x:Name="UserActionFlexLayout" BindableLayout.ItemsSource="{Binding DisplayedUserActions}" JustifyContent="Start" Wrap="Wrap" Direction="Row">
<BindableLayout.ItemTemplate>
<DataTemplate>
-- Datatemplate --
</DataTemplate>
</BindableLayout.ItemTemplate>
</FlexLayout>
</ScrollView>
Based on your code, the main axis is horizontal direction with multiple lines. So you could set the alignment of cross axis(vertical direction) using AlignContent.
You could set like this:
<FlexLayout x:Name="UserActionFlexLayout" ... AlignContent="Start">
By the way, i think you could use CollectionView instead for this case. You could customize the layout you want. For example, you could use ItemsLayout property:
<CollectionView ItemsSource="{Binding DisplayedUserActions}">
<!--set 3 columns, and itemspacing for each direction-->
<CollectionView.ItemsLayout>
<GridItemsLayout Orientation="Vertical"
Span="3" VerticalItemSpacing="20" HorizontalItemSpacing="20"/>
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
<DataTemplate>
...
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
Also, you don't have to put it in a ScrollView as CollectionView can scroll itself.
For more info, you could refer to FlexLayout and Specify CollectionView layout
Hope it works for you.
I have been dipping my toes in the .NET Maui framework, but unfortunately so far it has been quite disappointing. There seem to be multiple errors related to Shell (title view not working properly) and controls themselves. I have the following main page xaml file:
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="MauiApp1.MainPage">
<StackLayout Background="#111111" >
<Frame HasShadow="True" Margin="10" CornerRadius="10" BackgroundColor="#222222">
<StackLayout Spacing="30">
<Grid ColumnDefinitions="30,*">
<Label Text="R" FontSize="Medium" TextColor="White" />
<Slider GridLayout.Column="1" MinimumTrackColor="Red" ThumbColor="Red" MaximumTrackColor="#AAAAAA" />
</Grid>
<Grid ColumnDefinitions="30,*">
<Label Text="G" FontSize="Medium" TextColor="White" />
<Slider GridLayout.Column="1" MinimumTrackColor="#7FFF00" ThumbColor="#7FFF00" MaximumTrackColor="#AAAAAA" />
</Grid>
</StackLayout>
</Frame>
</StackLayout>
</ContentPage>
which is just a stack layout with a single frame that houses two sliders with labels. However, the two sliders seem to have a predefined width, as they are not filling the remaining space:
As soon as I add anything to any of the controls in the xaml while the app is running, for example a green background to the first grid, both sliders resize to the correct size:
However, when I reload the application with this change, the sliders go back to the wrong size:
There are additional issues that I encountered as well, when placing this content page as a flyout item in the shell where android behaviour was as described here, but additionally the Sliders are not interactable in Windows version. In this example with a clean project they do work in Windows version.
Try with any third-party packages like syncfusion, etc. to meet your requirements.
I'm new to this community / Xamarin, and I've been stuck on this for a while so I need to reach out for help now.
I have a CarouselView of ContentViews and one of the view pages need to be validated so when the field is empty, I can revert back the correct carousel page using the Current Item binding BUT - although I am correctly retrieving the current item and the content view, the UI/binding isn't updating.
ContentViews is the ObservableCollection.
<Label Text="{Binding Source={x:Reference carouselView}, Path=CurrentItem,
StringFormat='Current item: {0}', FallbackValue='Current item:'}"/>
<Label Text="{Binding Source={x:Reference carouselView}, Path=Position,
StringFormat='Position: {0}'}"/>
<CarouselView
x:Name="carouselView"
IndicatorView="indicatorView"
ItemsSource="{Binding ContentViews}"
CurrentItem="{Binding CurrentItem}"
Position="{Binding Position}"
CurrentItemChanged="OnCurrentItemChanged"
PositionChanged="OnPositionChanged">
<CarouselView.ItemTemplate>
<DataTemplate>
<ContentView Content="{Binding .}" />
</DataTemplate>
</CarouselView.ItemTemplate>
</CarouselView>
Do you have INotifyPropertyChanged implemented in you Binding Source?
check this , also check that the CarouselView Binding source is your desired class.
I'm using the list View in XAML, and using below codw to draw a rectangular box, I want to place a 2 letter alphabets inside the box like windows phone contacts they palce alphabets inside the rectangle box. Is there any way to place a text inside rectangle box
<BoxView Color="Green" WidthRequest="50" HeightRequest="20" HorizontalOptions="Start">
You want to replicate what it looks like on WinPhone.
(Sorry no code, I don't have my computer with me)
Use a flattened Frame (HasShadows=false, CornerRadius=0)
Set the Padding=10, Margin=3 (breathing room),
BackgroundColor=Green
Put a Label inside the Frame
Set FontSize=25, TextColor=White, Center it (Horizontal and
Vertical Alignment), FontAttributes=Bold
Hope this helps.
You can use like this
<StackLayout Padding="1" BackgroundColor="Black" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<StackLayout BackgroundColor="White" HorizontalOptions="FillAndExpand" >
<Label Text="Sample" TextColor="Black" HorizontalTextAlignment="Start"/>
</StackLayout>
</StackLayout>
May this will solve the problem.
Hi I am working in shoping app and design like, I have already used tint image:
How I can do that, I I can create a circel like this image
I am not sure why you are not using icons from the resources or get the images from rest api.
This is only needed if you want to create dynamic icons.
If that is the case, use a Frame and put the image on it.
<Frame CornerRadius="15" AbsoluteLayout.LayoutBounds="120, 10, 30, 30" Padding="5" VerticalOptions = "FillAndExpand" HasShadow= "false" BackgroundColor="red" >
<StackLayout Orientation="Vertical" Spacing="0" HorizontalOptions="Center" VerticalOptions="Center">
<Label Text="1" VerticalTextAlignment="Center" HorizontalOptions="Center" />
</StackLayout>
</Frame>
the important thing to note is that , "cornerRadius" should be help the size of "AbsoluteLayout.LayoutBounds" width and size.
