How do you close a view from another view in .net maui?

January 24, 2023

I am trying to implement a loading/is busy logic in my app. When the item is selected from a collection view it shows a popup of a activity indicator which works fine. But, I am unable to close the popup once the other view loads. I have tried calling Close() but that doesnt do anything. So pretty much just trying to figure out the best way to show a activity indicator then close it once the process is done.

async void ItemSelected(object sender, SelectionChangedEventArgs e)
    {
        var popup = new LoadingPopup();
        this.ShowPopup(popup);
        var item = e.CurrentSelection.FirstOrDefault();
        if (item != null)
        {
            await Navigation.PushAsync(new YearPage(item) {BindingContext = item });
            
            //await Application.Current.MainPage.Navigation.PushAsync(new YearPage
            //{
            //    BindingContext = item
            //});
        }
    }

Calling close on the popup from a different view page(as the method doing the work is on a different page and I want to close the popup once it is done) doesnt work.

>Solution :

you need to pass a reference to the popup to the 2nd page

var popup = new LoadingPopup();
this.ShowPopup(popup);
var item = e.CurrentSelection.FirstOrDefault();
if (item != null)
{
  await Navigation.PushAsync(new YearPage(item, popup) {BindingContext = item });

then you would have to modify the YearPage constructor to accept that 2nd parameter

then you would have a public method on LoadingPopup to dismiss via the Close() method
