I have a flexlayout when a display some items in a frame, but all the items that have labels with text on 2 lines the icon gets pushed up and the label text do not align with each other. Any suggestions of what I am doing wrong?
my code
<Grid>
<ScrollView>
<FlexLayout
Padding="8"
AlignContent="Start"
AlignItems="Start"
BindableLayout.ItemsSource="{Binding MyItems}"
Direction="Row"
JustifyContent="Start"
Wrap="Wrap">
<BindableLayout.ItemTemplate>
<DataTemplate>
<StackLayout HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"
Margin="4,4,4,4"
FlexLayout.AlignSelf="Start"
FlexLayout.Basis="{OnIdiom Phone='50%',
Tablet='33%'}">
<Frame
Margin="0"
Padding="0"
BorderColor="DarkGray"
CornerRadius="10"
HeightRequest="130"
HasShadow="True">
<StackLayout VerticalOptions="Center" HorizontalOptions="Center">
<Image Aspect="AspectFit" Source="PhotoIcon.png"
Margin="0,20,0,0" WidthRequest="50" HeightRequest="50"/>
<Label Text="{Binding Name}" Margin="0,10,0,10" />
</StackLayout>
</Frame>
</StackLayout>
</DataTemplate>
</BindableLayout.ItemTemplate>
</FlexLayout>
</ScrollView>
</Grid>
Improve your code
<Label Text="{Binding Name}" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" Margin="0,10,0,10" />
Update:
Because StackLayout will not fit the size of its child elements ,so I suggest you can use Grid instead of it.
<Grid VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
<Grid.RowDefinitions>
<RowDefinition Height="0.5*" />
<RowDefinition Height="0.5*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
</Grid.ColumnDefinitions>
<Image Grid.Row="0" Aspect="AspectFit" Source="PhotoIcon.png" Margin="0,20,0,0" WidthRequest="50" HeightRequest="50"/>
<Label Grid.Row="1" Text="{Binding Name}" Margin="0,10,0,10" HorizontalTextAlignment="Center" VerticalTextAlignment="Center"/>
</Grid>

I looked for open codes or nuget that could help me with this question, I would like to create a list of Cards like these in the images, where I could have several click events, but could get the id of the item that fills the card.
Eu tentei com CollectionView, porem não consigo pegar a id do item do card, nem com uma label e o x:Name atribuído a essa label.
Segue o cod xaml que criei

in your event handler
protected void ButtonClicked(object Sender, EventArgs args)
{
var btn = (Button)sender;
var item = (MyClassName)btn.BindingContext;
// now you can access an property on item that you need
}
I want to achieve a space between the different groupings in a listview like my picture.
How can I do this through xaml?
I have tried adding the some margin and padding to the GroupHeaderTemplate without any luck.
<ListView.GroupHeaderTemplate>
<DataTemplate>
<ViewCell>
<Frame Margin="0,20,0,0" Padding="0,0,0,0" BackgroundColor="#324458" >
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="40" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="7*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label HorizontalOptions="StartAndExpand" VerticalOptions="CenterAndExpand" HorizontalTextAlignment="Start" VerticalTextAlignment="Center" TextColor="white" Grid.Row="0" Grid.Column="1" Text="{Binding Name}"/>
<Label HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" Grid.Row="0" Grid.Column="0" BackgroundColor="#2D3334" Margin="0,3,0,3" TextColor="#C4ced8" Text="LPic" />
<Label HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" BackgroundColor="#2D3334" Grid.Row="0" Grid.Column="2" TextColor="#C4ced8" Margin="0,3,0,3" Text="30. SEP" />
</Grid>
</Frame>
</ViewCell>
</DataTemplate>
</ListView.GroupHeaderTemplate>
You can put the Frame in another Frame and set the Padding of it
<ViewCell>
<Frame Margin="0" Padding="0,20,0,0" BackgroundColor="#324458" >
<Frame >
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="40" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="7*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Label HorizontalOptions="StartAndExpand" VerticalOptions="CenterAndExpand" HorizontalTextAlignment="Start" VerticalTextAlignment="Center" TextColor="white" Grid.Row="0" Grid.Column="1" Text="{Binding Name}"/>
<Label HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" Grid.Row="0" Grid.Column="0" BackgroundColor="#2D3334" Margin="0,3,0,3" TextColor="#C4ced8" Text="LPic" />
<Label HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" BackgroundColor="#2D3334" Grid.Row="0" Grid.Column="2" TextColor="#C4ced8" Margin="0,3,0,3" Text="30. SEP" />
</Grid>
</Frame>
</Frame>
</ViewCell>
You could try adding padding to the top and bottom of the Frame e.g. Padding="0,20,0,20"? play with the values for top and bottom padding until you get your ideal result.
If that doesn't work try adding the padding to the ViewCell.
What you can do is add another RowDefinition to the grid and give it some height saw 20 and make this new RowDefinition as the first row and existing row as the second row.
i'm very new to xamarin forms so, sorry if i ask obvious question.
I need to build a frame with labels and pictures within. It should look like the following
By now i tried this:
<Frame OutlineColor="#2e5982"
BackgroundColor="#2e5982"
HorizontalOptions="Fill"
Grid.Column="0"
Margin="0">
<Frame.Content>
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<Label x:Name="LbSecsHead" Font="Arial" TextColor="White" Text="Status" HorizontalOptions="Center"/>
<Grid HorizontalOptions="Fill" VerticalOptions="Fill">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*"/>
<ColumnDefinition Width="50*"/>
</Grid.ColumnDefinitions>
<StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" Grid.Column="0">
<StackLayout Orientation="Horizontal" BackgroundColor="Accent">
<Image x:Name="SignalSec6" Source="{local:ImageResource Fusion.Pictures.GreenSignalMaterialOff.png}" Aspect="Fill" HorizontalOptions="Start" VerticalOptions="Start"/>
<Label Font="Arial" TextColor="White" Text="6" HorizontalOptions="Center"/>
</StackLayout>
</StackLayout>
<StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" Grid.Column="1">
<StackLayout Orientation="Horizontal">
<Image x:Name="SignalSec5" Source="{local:ImageResource Fusion.Pictures.GreenSignalMaterialOn.png}" Aspect="Fill" HorizontalOptions="Start" VerticalOptions="Start"/>
<Label Font="Arial" TextColor="White" Text="5" HorizontalOptions="Center"/>
</StackLayout>
</StackLayout>
</Grid>
</StackLayout>
</Frame.Content>
</Frame>
The frame is inside a grid column of an outer layout, and here i just limited to the first two icons since result is the same for multiple identical items stacked vertically. Regardless of many tryouts i've done with Horizontal and Vertical options i always obtain this:
The frame sizing with respect to outer layout is correct but not the elements inside. Strange think (at least to me) is that picture looks like being outside of the stacklayout as can be seen by the pink background of the layout. Basically i need the pictures to autofit the layout.
Any hint would be appreciated
Thanks
You'll need to use Span :
Spans – configure elements to span across multiple rows or columns.
<Label Text="SEC" FontSize="40" HorizontalOptions="CenterAndExpand"/>
<Grid HorizontalOptions="CenterAndExpand">
<Grid.RowDefinitions>
<RowDefinition Height="80" />
<RowDefinition Height="80" />
<RowDefinition Height="80" />
<RowDefinition Height="80" />

I have a ListView that contains a grid with some Labels, I want to put a separating line between two labales, but in doing so I have to indicate to the BoxView in what row of the grid it should go, and in doing so, the BoxView covers the entire size of the grid. line, is there any way that only a thin line is drawn and not the thick blue line?
