Examples

If you want to replicate the behavior of Microsoft Edge with the TabView, you can use the following setup:

<controls:TabView TabWidthBehavior="Equal"
                  CanCloseTabs="True"
                  IsCloseButtonOverlay="True"
                  CanDragItems="True"
                  CanReorderItems="True"
                  AllowDrop="True">
  <controls:TabView.Resources>
    <x:Double x:Key="TabViewItemHeaderMinHeight">32</x:Double>
    <x:Double x:Key="TabViewItemHeaderMinWidth">90</x:Double>
    <x:Double x:Key="TabViewItemHeaderMaxWidth">200</x:Double>
  </controls:TabView.Resources>
  ...
</controls:TabView>

The TabView supports data binding as well. The following example shows binding the TabView to a collection of 'DataItems' which have both 'Value' and 'MyText' properties:

<controls:TabView x:Name="TabItems"
                  ItemsSource="{Binding TabItemCollection}">
  <controls:TabView.ItemHeaderTemplate>
    <DataTemplate>
      <TextBlock>
        <Run Text="{Binding Value}"/>
        <Run Text=": "/>
        <Run Text="{Binding MyText}"/>
      </TextBlock>
    </DataTemplate>
  </controls:TabView.ItemHeaderTemplate>
  <controls:TabView.ItemTemplate>
    <DataTemplate>
      <StackPanel>
        <TextBlock Margin="8">
          <Run Text="Tab Value: "/>
          <Run Text="{Binding Value}" />
        </TextBlock>
        <TextBlock Margin="8,0,0,0" Text="Some other shared content..." />
      </StackPanel>
    </DataTemplate>
  </controls:TabView.ItemTemplate>
</controls:TabView>

Note

It's recommended to use an ObservableCollection when working with the TabView.
