Hi, 

I followed the tutorial here: http://www.telerik.com/help/silverlight/radtabcontrol-item-templates-and-selectors.html to bind the headers of my tabs to data like this:

<telerikNavigation:RadTabControl.ItemContainerStyle>
                    <Style TargetType="telerikNavigation:RadTabControl">
                        <Setter Property="HeaderTemplate">
                            <Setter.Value>
                                <DataTemplate>
                                    <StackPanel Orientation="Horizontal">
                                        <TextBlock x:Name="HeaderText" Text="{Binding Header}" />
                                    </StackPanel>
                                </DataTemplate>
                            </Setter.Value>
                        </Setter>
                </Style>

But I get an error at runtime saying "Invalid attribute value "HeaderTemplate"  for property Property on the:
     <Setter Property="HeaderTemplate"> line.

I've set a ContentTemplate up to bind to the class which is working for the content of the tabs, but I cant set the header.
Thanks

Hello stephen,

The TargetType of the Style defined as an ItemContainerStyle should be telerikNavigation:RadTabItem:
<telerikNavigation:RadTabControl.ItemContainerStyle>
    <Style TargetType="telerikNavigation:RadTabItem">
        <Setter Property="HeaderTemplate">
            <Setter.Value>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock x:Name="HeaderText" Text="{Binding Header}" />
                    </StackPanel>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</telerikNavigation:RadTabControl.ItemContainerStyle>

Give it a try and let me know if it works for you or if you need more info.
