我是WPF的新手，正在尝试使用Ribbon控件。
我在应用程序中只有一个选项卡，希望隐藏标题但仍然显示选项卡本身。
我尝试了各种属性和样式，但只能隐藏整个选项卡。
我尝试过：ribbontab可见性，ribbontab.header可见性，在TabHeaderItemCollection中设置hidden，将xaml样式应用于ribbontab中的ribbontabheader元素，尝试tabheadertemplate属性，并且通常在API中搜索任何可能相关的内容。
谷歌只提供如何隐藏整个选项卡的方法。
还有其他想法吗？
我成功地通过将控件向上移动47像素来隐藏选项卡标题和应用程序菜单...
<r:Ribbon Margin="0,-47,0,0" DockPanel.Dock="Top" x:Name="ribbon">
<r:Ribbon DockPanel.Dock="Top" x:Name="ribbon">
<r:Ribbon.ApplicationMenu>
<r:RibbonApplicationMenu Visibility="Collapsed" />
</r:Ribbon.ApplicationMenu>
class RibbonNoTab : Ribbon
{
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
var ctrl = this.GetDescendants<Grid>().FirstOrDefault();
if (ctrl != null)
{
ctrl.RowDefinitions[1].Height = new GridLength(0, System.Windows.GridUnitType.Pixel);
}
}
}
public class RibbonBehavior
{
public static bool GetHideRibbonTabs(DependencyObject obj)
{
return (bool)obj.GetValue(HideRibbonTabsProperty);
}
public static void SetHideRibbonTabs(DependencyObject obj, bool value)
{
obj.SetValue(HideRibbonTabsProperty, value);
}
// Using a DependencyProperty as the backing store for HideRibbonTabs. This enables animation, styling, binding, etc...
public static readonly DependencyProperty HideRibbonTabsProperty =
DependencyProperty.RegisterAttached("HideRibbonTabs", typeof(bool), typeof(RibbonBehavior), new UIPropertyMetadata(false,OnHideRibbonTabsChanged));
public static void OnHideRibbonTabsChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
if (d == null || d.GetType() != typeof(Ribbon)) return;
(d as Ribbon).Loaded += ctrl_Loaded;
}
static void ctrl_Loaded(object sender, RoutedEventArgs e)
{
if (sender == null || sender.GetType() != typeof(Ribbon)) return;
Ribbon _ribbon = (Ribbon)sender;
var tabGrid = _ribbon.GetDescendants<Grid>().FirstOrDefault();
tabGrid.RowDefinitions[1].Height = new GridLength(0, System.Windows.GridUnitType.Pixel);
foreach (Line line in _ribbon.GetDescendants<Line>())
line.Visibility = Visibility.Collapsed;
}
}
然后在您的XAML中：
<Ribbon SelectedIndex="0" a:RibbonBehavior.HideRibbonTabs="true">
这将为您提供一个漂亮的正方形丝带盒，没有标签：
省略折叠行代码会在标签原位置留下一个小凸起，这让我感到不舒服。
如果您没有使用MVVM，也可以直接将该装入代码放入代码后面，或者使用EventToCommand。 这种方法不太可重用，但它具有相同的结果。
编辑：这是GetDescendant方法的代码：

将白色填充替换为您背景的颜色。还要注意，缎带是网格行1，而后放置的线是网格行0。
