How to Disable Keyboard Navigation in WPF MenuAdv

This example demonstrates how to disable keyboard navigation in the WPF MenuAdv control, part of the Syncfusion WPF suite. By default, MenuAdv allows navigation through menu items using keys such as Arrow, Tab, and Enter. In some scenarios, you may want to restrict this behavior so that navigation occurs only through mouse interaction or custom logic.

Why Disable Keyboard Navigation?

Disabling keyboard navigation can be useful when:

• Keyboard shortcuts are reserved for other operations.
• You want to maintain a specific user experience without keyboard-based menu navigation.

Implementation Overview

You can disable keyboard navigation in MenuAdv by handling the PreviewKeyDown event and marking specific keys as handled.

Code Example

XAML

<syncfusion:MenuAdv Height="30" Width="150" PreviewKeyDown="MenuAdv_PreviewKeyDown">
    <syncfusion:MenuItemAdv Header="File">
        <syncfusion:MenuItemAdv Header="New" />
        <syncfusion:MenuItemAdv Header="Open" />
    </syncfusion:MenuItemAdv>
    <syncfusion:MenuItemAdv Header="View">
        <syncfusion:MenuItemAdv Header="Zoom In" />
        <syncfusion:MenuItemAdv Header="Zoom Out" />
        <syncfusion:MenuItemAdv Header="Normal View" />
    </syncfusion:MenuItemAdv>
</syncfusion:MenuAdv>

C#

private void MenuAdv_PreviewKeyDown(object sender, KeyEventArgs e)
{
    switch (e.Key)
    {
        case Key.Left:
        case Key.Right:
            e.Handled = true; // Disable left/right navigation
            break;
        default:
            break;
    }
}
