Question

I have this code in MainPage.xaml:

<controls:PivotItem Header="first">
    <ListBox x:Name="MyListBox" Margin="0,0,-12,0" ItemsSource="{Binding ListBoxItem}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal" Height="132">
                    <TextBlock Text="{Binding text}" />
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</controls:PivotItem>

And I need to create N PivotItem’s in runtime with such model. How can I do it?

Let your PivotItem delaration be a Static Resource.

<UserControl.Resources>

<DataTemplate x:Key="MyPivotItemTemplate">
   <controls:PivotItem Header="first" >
                <ListBox x:Name="MyListBox" Margin="0,0,-12,0" ItemsSource="{Binding ListBoxItem}">
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal" Height="132">
                                <TextBlock Text="{Binding text}" />
                            </StackPanel>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>
            </controls:PivotItem>
</DataTemplate>

</UserControl.Resources>

Then in your Pivot declaration use it as a template for your items.

<Pivot .... ItemsTemplate="{StaticResource MyPivotItemTemplate}" Items="{Binding MyCollectionInDataContext}"

This way, each time you add something to a MyCollectionInDataContext, a PivotItem is created according to your defined template.
