Xamarin 表单 - 如何禁用 MasterDetailPage 菜单按钮

Question

I would to disable the top left button of the Main Menu when the busy indicator is shown.

I already found the point where I can make this edit, but I haven't find how to disable this button.

Anyone can help me please? :)

When you say "disable" I'm assuming you mean get rid of the Navigation bar, which contains the menu icon completely? If so, I use this code when I set the IsBusy property to true:

NavigationPage.SetHasNavigationBar(this, false);

Then when it's no longer busy just set it to true for it to reappear

NavigationPage.SetHasNavigationBar(this, true);
