How can I display a ContentView in a ContentPage-CodePudding

I created a sftabView, every SfTabItem have a ContentView so I created an other View to display it in this ContentView. so the question is how to make this happened? This is the ContentView which I wanted to display in the ContentPage

<?xml version="1.0" encoding="utf-8" ?>
<ContentView    
    xmlns="http://xamarin.com/schemas/2014/forms"
    x:Class="App5.Views.Self_Trainig"

    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
  
    NavigationPage.HasNavigationBar="False">

    <ContentView.Resources>
        <ResourceDictionary>
    ............
        </ResourceDictionary>
    </ContentView.Resources>

    <ContentView.Content>
        <AbsoluteLayout>
...............
        </AbsoluteLayout>

    </ContentView.Content>
</ContentView>

and this is my ContentPage:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:tabView="clr-namespace:Syncfusion.XForms.TabView;assembly=Syncfusion.SfTabView.XForms"
             x:Class="App5.Views.Accueil">
    <ContentPage.Content>
        <tabView:SfTabView OverflowMode="DropDown" VisibleHeaderCount="3" BackgroundColor="White">
            <tabView:SfTabItem Title="Self Training">
                <tabView:SfTabItem.Content>
""the code to display it here""
                </tabView:SfTabItem.Content>
            </tabView:SfTabItem>

            <tabView:SfTabItem Title="Contacts">
                <tabView:SfTabItem.Content>
                    <Grid BackgroundColor="White" x:Name="ContactsGrid" />
                </tabView:SfTabItem.Content>
            </tabView:SfTabItem>

        </tabView:SfTabView>
    </ContentPage.Content>
</ContentPage>

CodePudding user response：

<ContentPage
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:mynamespace=clr-namespace:App5.Views" 
    ...>
...
    <tabView:SfTabItem.Content>
        <mynamespace:Self_Trainig ... />
    </tabView:SfTabItem.Content>

Explanation:

Add an xmlns:... definition for the namespace your ContentView is in.
Add an element with that namespace and the class name of your ContentView.
...: After the class name, you can add any needed attributes. Just like any other ContentView.
