Load PageContent into SfTabView

This article explains about how to load content of page into Xamarin.Forms SfTabView

Creating the project

Create a new BlankApp (Xamarin.Forms.Portable) application in Xamarin Studio or Visual Studio for Xamarin.Forms.

Adding SfTabView in Xamarin.Forms

Add the required assembly references to the PCL and renderer projects as discussed in the Assembly deployment section.

Import the control namespace as shown in the following code.

[XAML]

xmlns:tabView="clr-namespace:Syncfusion.XForms.TabView;assembly=Syncfusion.SfTabView.XForms"

[C#]

using Syncfusion.XForms.TabView;

Set the control to content in ContentPage.

[XAML]

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

[C#]

public MainPage()   
{   
    InitializeComponent();       
    tabView = new SfTabView();   
    this.Content = tabView;  
}  

Adding ListView in SfTabView

Create a view model class with the ContactsInfo collection property, which is initialized with required number of data objects.

[C#]

public class ContactInfo
{
	public string Name { get; set; }
	public long Number { get; set; }
}

public class ContactsViewModel : INotifyPropertyChanged
{
	private ObservableCollection<ContactInfo> contactList;
	public event PropertyChangedEventHandler PropertyChanged;

	public ObservableCollection<ContactInfo> ContactList
	{
		get { return contactList; }
		set { contactList = value; }
	}
	public ContactsViewModel()
	{
	ContactList = new ObservableCollection<ContactInfo>();
	ContactList.Add(new ContactInfo{Name = "Aaron",Number = 7363750});
	ContactList.Add(new ContactInfo { Name = "Adam", Number = 7323250 });
	ContactList.Add(new ContactInfo { Name = "Adrian", Number = 7239121 });
	ContactList.Add(new ContactInfo { Name = "Alwin", Number = 2329823 });
	ContactList.Add(new ContactInfo { Name = "Alex", Number = 8013481 });
	ContactList.Add(new ContactInfo { Name = "Alexander", Number = 7872329 });
	ContactList.Add(new ContactInfo { Name = "Barry", Number = 7317750 });
	}
}

Binding data to ListView

Bind the items source of the ListView, and set the required appearance in its ItemTemplate property in which the list view can be hosted within the content region of tab item.

[XAML]

   <ContentPage.Content>
        <tabView:SfTabView BackgroundColor="#f6f6f6" x:Name="tabView">
            <tabView:SfTabItem Title="{Binding Title1}">
                <tabView:SfTabItem.Content>
                    <Grid BackgroundColor="White" x:Name="AllContactsGrid" >
                        <ListView x:Name="ContactListView" 
                                  ItemsSource="{Binding ContactList}"
                                  RowHeight="75">
                            <ListView.BindingContext>
                                <local:ContactsViewModel />
                            </ListView.BindingContext>
                            <ListView.ItemTemplate>
                                <DataTemplate>
                                    <ViewCell>
                                        <StackLayout Orientation="Vertical" Margin="30,0,0,0">
                                            <Label 
                                                Text="{Binding Name}"
                                                FontSize="24"  />
                                            <Label 
                                                Text="{Binding Number}" 
                                                FontSize="20" 
                                                TextColor="LightSlateGray" />
                                        </StackLayout>
                                    </ViewCell>
                                </DataTemplate>
                            </ListView.ItemTemplate>
                        </ListView>
                    </Grid>
                </tabView:SfTabItem.Content>
            </tabView:SfTabItem>
            <tabView:SfTabItem Title="Favorites">
                <tabView:SfTabItem.Content>
                    <Grid BackgroundColor="Green" x:Name="FavouritesGrid" />
                </tabView:SfTabItem.Content>
            </tabView:SfTabItem>
            <tabView:SfTabItem Title="Contacts">
                <tabView:SfTabItem.Content>
                    <Grid BackgroundColor="Blue" x:Name="ContactsGrid" />
                </tabView:SfTabItem.Content>
            </tabView:SfTabItem>
