I want to hide and display a tab based on a IsVisible property on a QTab that will be bound in the RadTab's ItemSource.

Here are the classes I am using
public class QTabs
    public ObservableCollection<QTab> Tabs { get; set; }
    public QTabs()
        Tabs = new ObservableCollection<QTab>
                new QTab[] {
                    new QTab { Header="Header 1",Value="Value 1"},
                    new QTab { Header="Header 2",Value="Value 2"},
                    new QTab { Header="Header 3",Value="Value 3", IsVisible= Visibility.Collapsed},
                    new QTab { Header="Header 4",Value="Value 4"},
                    new QTab { Header="Header 5",Value="Value 5"}
public class QTab
    public string Header { get; set; }
    public string Value { get; set; }
    public Visibility IsVisible { get; set; }
    public QTab()
        IsVisible = Visibility.Visible;

public MainPage()
    AllTabs = new QTabs();
    DataContext = this;
xaml snippets
<my3:RadTabControl x:Name="tabscon" Grid.Row="1" DataContext="{Binding AllTabs}" ItemsSource="{Binding Tabs}">
        <Style TargetType="my3:RadTabItem">
            <Setter Property="HeaderTemplate">
                        <TextBlock Text="{Binding Header}"/>

The above works so the binding is fine but when I add
<Setter Property="Visibility" Value="{Binding IsVisible}"/>
To the style I get an error that says I cannot set a readonly property.  Is there any way I can bind the the TabItems Visibility so I can dynamically had the tab.

Hi anester,

In this case you can use ContainerBindings. Could you please examine the attached sample project and if you have further questions do not hesitate to ask?
