I have ListView here and I can't get the items to center vertically:
<ListView x:Name="TasksList" ItemSelected="TasksList_ItemSelected">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Text="{Binding name}" Padding="20, 0, 0, 0"></Label>
<Label Grid.Row="0" Grid.Column="1" Text="{Binding status}" HorizontalTextAlignment="End" Padding="0,0,20,0" TextColor="{Binding statusColor}"></Label>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I have tried adding a StackLayout around my labels and played with VericalOptions and VerticalTextOptions, but nothing seems to work
Just add the following code for your Grid in your ListView:
VerticalOptions="Center"
Please refer to the following code:
<ListView x:Name="lstView" RowHeight="60">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid VerticalOptions="Center">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Text="{Binding name}" Padding="20, 0, 0, 0"></Label>
<Label Grid.Row="0" Grid.Column="1" Text="{Binding status}" HorizontalTextAlignment="End" Padding="0,0,20,0" ></Label>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I created a demo according to your code, the result is:

What can I do to show the shadow all around the frame? Please help and thanks.
EDIT
This is what I have with Margin=2 on Frame
Margin=50
Padding=50
Just to show how it behaves
At first, you can create a new frame in your project to check if the cause is the renderer or not. Such as:
<Frame Margin="20" CornerRadius="10" HasShadow="True">
<Label Text="TestShaw" HorizontalOptions="Center"/>
</Frame>
If the shadow shows correctly, the cause maybe the layout or the margin of your frame. So you can change the values of it.
If the shadow shows incorrectly too, you may need to use a custom renderer for the frame. Such as:
[assembly: ExportRenderer(typeof(Myframe), typeof(MyFrameRenderer))]
namespace App36.Droid
{
public class MyFrameRenderer : Xamarin.Forms.Platform.Android.FastRenderers.FrameRenderer
{
public MyFrameRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<Frame> e)
{
base.OnElementChanged(e);
CardElevation = 50;
SetOutlineSpotShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
SetOutlineAmbientShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
}
}
}
But in my project, both of them shows correctly. So if you need more information, you can check the link following.
Link: Xamarin forms Shadow on Frame in Android
And here is the frame in my project:
If the platform is ios for your project, please check this case:Forms frame isn't the same on iOS
Currently I use MasterDetailPage but I want to change my project model to Shell.
How can I generate FlyoutItems dynamically like my old version of MasterDetail?
<StackLayout>
<ListView x:Name="MenuItemsListView"
SeparatorVisibility="None"
HasUnevenRows="true"
ItemsSource="{Binding MenuItems}">
<ListView.Header>
<Grid BackgroundColor="#8f0000">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="10"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="80"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Label
Grid.Column="1"
Grid.Row="2"
Text="{Binding Title}"
Style="{DynamicResource SubtitleStyle}"
TextColor="#d7d9b4"
FontSize="24"/>
</Grid>
</ListView.Header>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Padding="15,10" HorizontalOptions="FillAndExpand">
<Label VerticalOptions="FillAndExpand"
VerticalTextAlignment="Center"
Text="{Binding MenuTitle}"
d:Text="{Binding .}"
FontSize="20"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
Do you have example with dynamic FlyoutItems?
You can use FlyoutContentTemplate, by using it you are telling Shell to overwrite/replace whatever the Flyout content that was auto-generate based on your AppShell.xaml hierarchy by what you provide instead.
I guess by MenuItems you meant a list of flyout items.
<Shell Title="Shell Title" ...>
<Shell.FlyoutContentTemplate>
<DataTemplate>
<StackLayout>
<ListView x:Name="MenuItemsListView"
SeparatorVisibility="None"
HasUnevenRows="true"
ItemsSource="{Binding FlyoutItems}">
<ListView.Header>
<Grid BackgroundColor="#8f0000">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="10"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="80"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Label Grid.Row="2" Grid.Column="1"
TextColor="#d7d9b4"
Text="{Binding Title}"
FontSize="24"/>
</Grid>
</ListView.Header>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Padding="15,10"
HorizontalOptions="FillAndExpand">
<Label VerticalOptions="FillAndExpand"
VerticalTextAlignment="Center"
Text="{Binding MenuTitle}"
TextColor="Black"
FontSize="20"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</DataTemplate>
</Shell.FlyoutContentTemplate>
Sample code
public ObservableCollection<dynamic> FlyoutItems { get; set; }
public AppShell()
{
FlyoutItems = new ObservableCollection<dynamic>()
{
new { MenuTitle="MenuTitle1" },
new { MenuTitle="MenuTitle2" },
new { MenuTitle="MenuTitle3" },
new { MenuTitle="MenuTitle4" }
};
InitializeComponent();
BindingContext = this;
}
It is only a sample to show the idea, not sure about your data design, but maybe it is better to use FlyoutContentTemplate with an ObservableCollection of your Items and MenuItemTemplate to a separate list of Menus item.
I have a WebView filled with an HTML code that came from database.

When the WebView go off the screen, the values disappears.
How can I avoid this behavior?
Why the WebView is cleared?
Thank you!
EDIT:
I have find that the problem is the ListView.
When an Item of the ListView is outside of the screen, this problem is triggered, but I can't solve :(
I am using MasterDetailPage in Xamarin.Forms. I have set BackgroundImage property in OnAppearing() method. It works fine in android. But, In IOS image doesn't display.

Image is available in Resource Folder.
I have also face same issue and solved.
Try this Hope it will Help..
You could use a Relative layout to achieve the results
<RelativeLayout>
<Image Source="masterpagebg.png" Opacity="1"
RelativeLayout.WidthConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Width}"
RelativeLayout.HeightConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Height}"/>
<ListView RelativeLayout.WidthConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Width}"
RelativeLayout.HeightConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Height}" x:Name="MenuItemsListView" WidthRequest="200"
HasUnevenRows="true"
ItemsSource="{Binding MenuItems}"
SeparatorColor="White">
<ListView.Header>

<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="10"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="80"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Image Source="logo.png" Grid.Row="1" Grid.Column="1"></Image>

You should check if the image is set to the iOS project as BundleResource, if not you should set it as so. I myself had some troubles with this.
here Im getting list of data to which Im assigning it to a listview... In that i need to display user ratings to every Item.. So when the user rating is $.. I need to display 4stars in greeen color and another 1 star in gray color.. Im unable to do this.. Can anyone please tell me

There are plenty of samples and controls out there. You don't really need to do it yourself. Syncfusion offers some nice controls for Xamarin. There is a free Community License too.
I think that's what you want -> https://www.syncfusion.com/products/xamarin
