How to stop the RadialMenu from opening?
1 min read
When you click the navigation button, the SfRadialMenu opens automatically. This can be manually stopped by forcing the RadialMenu to remain closed. To achieve this,
- Retrieve the navigation button in the SfRadailMenu, and hook its MouseLeftButtonUp event.
- Handle the event by setting e.Handled=true.
This restricts the SfRadialMenu from opening.
The following code example demonstrates the same.
Xaml
<navigation:SfRadialMenu x:Name="radialMenu" Loaded="radialMenu_Loaded"> <navigation:SfRadialMenuItem Header="Cut"/> <navigation:SfRadialMenuItem Header="Copy"/> <navigation:SfRadialMenuItem Header="Paste"/> </navigation:SfRadialMenu>
C#
public partial class MainWindow : Window
{
bool CanOpen = false;
public MainWindow()
{
InitializeComponent();
}
private void radialMenu_Loaded(object sender, RoutedEventArgs e)
{
radialMenu.Loaded -= radialMenu_Loaded;
Button navigationButton = radialMenu.Template.FindName("PART_NavigationButton", radialMenu) as Button;
if(navigationButton!=null)
{
navigationButton.PreviewMouseLeftButtonDown += navigationButton_PreviewMouseLeftButtonDown;
}
}
void navigationButton_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (!CanOpen)
{
e.Handled = true;
}
}
}
