Xamarin Forms - Getting Rid of Back Button In Nav Bar

Question

Lets say the first page in the app is the login page and then it takes me to do the main menu screen, is there a way to get rid of the back button in the main menu navigatio

Answer 1

By using CustomRenderer, you call this function in ViewWillAppear in your customized view controller

public override void ViewWillAppear (bool animated)
{
    base.ViewWillAppear (animated);
    this.ParentViewController.NavigationItem.SetHidesBackButton (true, false); 
    //remember to use ParentViewController to reference to the NavigationViewController (if your contentPage is direct under a navigation controller. I don't know why but Xamarin must have a bug with SetHidesBackButton. If you call with this.NavigationItem.SetHidesBackButton(...), it should not work.
