how do you hide Quick Access Toolbar in a WPF's Ribbon?
6 Answers
For Microsoft Ribbon for WPF, you can hide it by using the VisualTreeHelper
. On the Loaded
event handler, just resize the row containing the Quick Access Toolbar to 0 :
private void RibbonLoaded(object sender, RoutedEventArgs e)
{
Grid child = VisualTreeHelper.GetChild((DependencyObject)sender, 0) as Grid;
if (child != null)
{
child.RowDefinitions[0].Height = new GridLength(0);
}
}
The Quick Access Toolbar is automatically hidden when the Ribbon control is in a RibbonWindow. When it is not, it seems impossible to hide it. I have already worked hours on this issue and was unable to hide it properly. But there is one simple workaround: Place the Ribbon control inside of a Panel and give it a negative top margin so it will slide outside of the Panel. Set the Panel's ClipToBounds property to true and the QAT will be hidden. By the way - there are multiple Ribbon implementations for WPF, even by Microsoft themselves ("Fluent Ribbon" and "Microsoft Ribbon for WPF"), so next time you should mention which one you are talking about.
Or if you want it all in the XAML, this works
<ribbon:Ribbon>
<ribbon:Ribbon.Loaded>CollapseQuickAccessToolbar</ribbon:Ribbon.Loaded>
<x:Code>
private void CollapseQuickAccessToolbar(Object sender, RoutedEventArgs e) {
((Grid)VisualTreeHelper.GetChild((DependencyObject)sender, 0)).RowDefinitions[0].Height = new GridLength(0);
}
</x:Code>
</ribbon:Ribbon>
