How to block button double click when navigating to other page

Question

I am navigating to other page after button onClick(). I want to avoid situation with double click. Now when I click button more than once, for example twice, before the next page is shown with the result, there are multiple instances of the next page created.

private async void Button_Clicked(object sender, EventArgs e)
{
    var newPage = new NewPage();
    await Navigation.PushAsync(newPage);
}

What should i need to be added in my code?

disable button on click.. and enable it again after other page gets loded — V-rund Puro-hit, Jan 22 '19 at 11:11

You could judge istapped when button is tapped like following code.

var _istapped = false;

private async void Button_Clicked(object sender, EventArgs e)
{
    if(_istapped)
        return;

    _istapped = true;

    var newPage = new NewPage();
    await Navigation.PushAsync(newPage);

    _istapped = false;
}
