How to close the NavigationDrawer when user tapped back button, and don't close main page

[Ahmed Aglan]

Dear,

I've a main page with navigation drawer, every thing is going well, but when I tapped on back button on my mobile to close the navigation drawer, the main page also closed. 

Is there is any property to close the navigation drawer only and remain in current page ?

I'm using Syncfusion.Xamarin.SfNavigationDrawer(v19.3.0.55)

Hi  Suganya Sethuraman,

Thank you for your replay, it helps me to fix issue, 

next is more enhanced code:

    protected override bool OnBackButtonPressed()

    {
      // true or false to disable or enable the action
      if (navigationDrawer.IsOpen)
      {
        navigationDrawer.ToggleDrawer();
        return true;
      }
      return base.OnBackButtonPressed();
    }
