I have a collectionview and command.The problem is that when I read the object to the command it is for some reason zero, sorry and please help where the error
XAML

CODE BEHIND
public PlacesList()
{
InitializeComponent();
BindingContext = this;
CallPlace = new Command<CustomPin>((key) =>
{
var currentPlace = key as CustomPin;
MapPage.PlacesHandler(currentPlace);
});
}
Pass data into the Command using the CommandParameter property
<TapGestureRecognizer CommandParameter={Binding .} Command="{Binding BindingContext.CallPlace, Source={x:Reference ListPlaces}}" />
Assuming CustomPin is the type of list object that you are binding to this CollectionView.
Also, use the XAML styler Vs extension it's free and it makes your XAML really presentable

I decided to add the logo to the specified location, but I do not know how this can be done
This can be achieved by adding a stacklayout to the outside of the frame.
Below is the code snippet for your reference:

There is a Row height property inside ListView:
C#:
RowHeightDemoListView.RowHeight = 100;
Xaml:
<ListView x:Name="RowHeightDemoListView" RowHeight="100" />
I have a CollectionView that is bound to a ObserableCollection called UserPermissions.
In that FrontUserPermissionsModel class I have another ObservableCollection called MyPermissions.
I am trying to do something like this:
<CollectionView x:Name="CollectionViewEmployees" Margin="0,10,0,0" ItemsSource="{Binding UserPermissions}" SelectionMode="Single" Grid.Row="0"
SelectionChangedCommand ="{Binding SelectedUSerPermissionsDetailsCommand}" SelectedItem="{Binding SelectedUSerPermission}">
<CollectionView.ItemTemplate>
<DataTemplate>
<StackLayout Padding="5,3,5,9">
.
.
.
.
<StackLayout x:Name="SettingItemsLayout" Grid.Row="7" BackgroundColor="red" Grid.Column="0" HeightRequest="300" Grid.ColumnSpan="2"
BindableLayout.ItemsSource="{Binding MyPermissions}" HorizontalOptions="FillAndExpand">
<BindableLayout.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="52*" />
<ColumnDefinition Width="48*" />
</Grid.ColumnDefinitions>
<Label FontSize="18" Grid.Column="0" BackgroundColor="Green" FontAttributes="Bold" HorizontalTextAlignment="Start" Text="{Binding Title}" TextColor="white" />
<Label FontSize="18" Grid.Column="1" FontAttributes="Bold" HorizontalTextAlignment="Start" Text="{Binding AccessLevel}" TextColor="white" />
</Grid>
</DataTemplate>
</BindableLayout.ItemTemplate>
</StackLayout>
</StackLayout>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
The UserPermission binding is working. But my syntax on how to bind the MyPermissions is incorrect and I am not sure how to fix it. Thanks.
Do you mean you want to let your StackLayout binding an other ObserableCollection in the viewmodel ?
You could use Binding Path :
Maybe something like：
<StackLayout x:Name="SettingItemsLayout" Grid.Row="7" BackgroundColor="red" Grid.Column="0" HeightRequest="300" Grid.ColumnSpan="2"
BindableLayout.ItemsSource="{Binding Source={x:Reference SettingItemsLayout},
Path=BindingContext.MyPermissions}" HorizontalOptions="FillAndExpand">
<BindableLayout.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="52*" />
<ColumnDefinition Width="48*" />
</Grid.ColumnDefinitions>
<Label FontSize="18" Grid.Column="0" BackgroundColor="Green" FontAttributes="Bold" HorizontalTextAlignment="Start" Text="{Binding Title}" TextColor="white" />
<Label FontSize="18" Grid.Column="1" FontAttributes="Bold" HorizontalTextAlignment="Start" Text="{Binding AccessLevel}" TextColor="white" />
</Grid>
</DataTemplate>
</BindableLayout.ItemTemplate>
</StackLayout>

The problem is the button is not clicking inside the Data template.
Can you guys please help me what should i do now?
Thank you..
Hard to say what is wrong. Could you show full xaml code, view code behind and your viewmodel
Is DeleteClicked is in code behind or in VM?

Can you please tell me how to stop the keyboard to hide the text box that is <Entry x:Name="txtentry" in above XAML.
It's quite a typical problem on iOS and there's a ready nuget plugin which you just need to import to your app and initialize. It will check whether the keyboard is not hiding the edited textbox and move the whole page up if it's needed.
