列表元素WPF之间的选项卡

这可以在XAML中通过设置以下两个属性来完成。

    <Style TargetType="ListBox" >
        <Setter Property="KeyboardNavigation.TabNavigation" Value="Continue" />
    </Style>

    <Style TargetType="ListBoxItem">
        <Setter Property="IsTabStop" Value="False" />
    </Style>

评论之后,具体来说:

private void ListBox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Tab)
    {
        ListBox lb = sender as ListBox;

        if(lb == null) return;

        if(lb.SelectedIndex < lb.Items.Count - 1)
        {
            GiveItemFocus(lb, lb.SelectedIndex + 1, typeof(TextBox));
            e.Handled = true;
        }
    }
}

private void GiveItemFocus(ListBox lb, int index, Type descentdantType)
{
    if(lb.Items.Count >= index || index < 0)
    {
        throw new ArgumentException();
    }

    ListBoxItem lbi = (ListBoxItem) lb.ItemContainerGenerator.ContainerFromIndex(index);

    lb.UnselectAll();

    lbi.IsSelected = true;

    UIElement descendant = (UIElement) FindVisualDescendant(lbi, o => o.GetType() == descentdantType);

    descendant.Focus();
}

private static DependencyObject FindVisualDescendant(DependencyObject dependencyObject, Predicate<bool> condition)
{
    //implementation not provided, commonly used utility
}

设置 e.Handled 若为true,将确保只在按Tab键时处理处理处理程序,并且不会激活默认行为。
