update tab header

[Jingmeng]

hi everyone,
i have a problem on changing tab header, what i did is bind header textblock with a property of a C# object, but once i modify the property, the textblock(tab header) did change
code is looks like :

    radTab.ItemContainerStyle = App.Current.Resources["TabItemStyle"] as Style;
    radTab.ItemsSource = TabCollection;

TabCollection.add(new TabItem(){Header = "aa", IconPath = "~/Images/Icon1.png", Content = object})

xaml looks like:

<Style x:Key="TabItemStyle" TargetType="telerikNavigation:RadTabItem">
    <Setter Property="HeaderTemplate" >
        <Setter.Value>
            <DataTemplate x:Key="TabHeader">
                <StackPanel Orientation="Horizontal"  >
                   <Image x:Name="HeaderIcon" Source="{Binding IconPath, Mode=TwoWay}" Margin="3, 0, 3, 0" Width="40" Height="20"/>
                   <TextBlock x:Name="HeaderText" Text="{Binding Header, Mode=TwoWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </StackPanel>
            </DataTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Height" Value="35" />
    <Setter Property="MaxWidth" Value="300" />
    <Setter Property="MinWidth" Value="120" />
    <Setter Property="ContentTemplate">
        <Setter.Value>
            <DataTemplate>
                <controlsToolkit:DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
                    <ContentPresenter Content="{Binding Content}"/>
                </controlsToolkit:DockPanel>
            </DataTemplate>
        </Setter.Value>
    </Setter>
</Style>

once i go change tabItemCollection, tab header remain the same, any suggest how can i update?

best regards

Hello Jingmeng,

Yout xaml code looks correct.

Can you confirm that the TabItem class implements INotifyPropertyChanged and that the PropertyChanged event is raised in the setter of the "Header" property?

If this is not the case then the binding will not update.

All the best,
