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
MENG
