Disable left/right keyboard navigation in menu

Question

Hi,I have an WPF app where I would like to allow the user to go back/forward in a particular control using the Left/Right arrow keys. However, I don't want the menu to get selected at the same time (this happens) - similar to be working in Excel, when the user moves around with the arrow keys, it should not affect the menu to be selected.Is there a way to disable keyboard navigation in the menuAdv menu?

Hi Bergsteinn,Thanks for using syncfusion products.You can achieve your requirement by making MenuAdv ExpandMode property as ExpandOnClick.




<syncfusion:MenuAdv  x:Name="MenuAdv" ExpandMode="ExpandOnClick" /> Here is a video and sample that works as expected.Video : https://www.syncfusion.com/downloads/support/forum/153619/ze/Menu-22714627.zip  Sample : https://www.syncfusion.com/downloads/support/forum/153619/ze/Menu1367634919.zip  Documentation: https://help.syncfusion.com/wpf/menu/orientation-support#expand-modes-supportQuery : Is there a way to disable keyboard navigation in the menuAdv menu?Yes, you can disable the keyboard navigation in menuadv control using MenuAdv.PreviewKeyDown event handler.Code Snippet




MenuAdv.PreviewKeyDown += MenuAdv_PreviewKeyDown;private void MenuAdv_PreviewKeyDown(object sender, KeyEventArgs e) 
{ 
    switch (e.Key) 
    { 
        case Key.Left: 
            e.Handled = true; 
            break; 
        case Key.Right: 
            e.Handled = true; 
            break; 
        default: 
            break; 
    } 
} Note: When you disable the keyboard navigation key you cann’t select the menu item using the left/right key.Regards,Durai
