Question

I have a Pivot control which I am using as following within the XAML.
I have bound the Pivot Title to a method on my view model as its content will vary depending upon what is being displayed.

 <controls:Pivot x:Name="MainPivot" ItemsSource="{Binding PivotItemHeaders}" Title="{Binding ApplicationTitle}"  >
        <controls:Pivot.HeaderTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Description}"/>
            </DataTemplate>
        </controls:Pivot.HeaderTemplate>
        <controls:Pivot.ItemTemplate>
            <DataTemplate>
                <ListBox x:Name="EventsListbox"
                         ItemsSource="{Binding allEventItems}"
                         ItemTemplate="{StaticResource EventDisplay3}"
                         SelectionChanged="EventsListbox_SelectionChanged"/>
            </DataTemplate>
        </controls:Pivot.ItemTemplate>
    </controls:Pivot>

The collection of items is being refreshed and the binding is working fine for these objects – however the Pivot title is not refreshing with the new value.
It seems stuck at the value when the page/pivot control was first shown.

Any ideas how I can get the pivot control to refresh? – Thanks

I just did a quick test, binding works just fine:

<controls:Pivot Title="MY APPLICATION" ItemsSource="{Binding Items}">
    <controls:Pivot.HeaderTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding LineOne}" />
        </DataTemplate>
    </controls:Pivot.HeaderTemplate>
    <controls:Pivot.ItemTemplate>
        <DataTemplate>
            <Grid>      
                <Button Content="Update" Click="Button_Click" />
            </Grid>
        </DataTemplate>
    </controls:Pivot.ItemTemplate>
</controls:Pivot>

And in the C#

private void Button_Click(object sender, RoutedEventArgs e)
{
    App.ViewModel.Items.Clear();
    App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "foo" });
    App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "bar" });
    App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "baz" });
}

So clearly you’re doing something very wrong. Post your code and we’ll take a look.

Update

Title Binding also works

XAML

<controls:Pivot Title="{Binding Title}">
    <controls:PivotItem Header="first">
        <Grid>
            <Button Click="Button_Click" Content="OK!" />
        </Grid>
    </controls:PivotItem>
</controls:Pivot>

C#:

private void Button_Click(object sender, RoutedEventArgs e)
{
    Title = "foobar!";
    PropertyChanged(this, new PropertyChangedEventArgs("Title"));
}
