MAUI Blazor App - Run Code On Any Page Load?

Question

Is it possible to run a piece of code on every time a page is loaded whether its being navigated to or any other scenario it may be?

Something like overriding OnNavigate method?

Answer 1

I thing that you can use also "Loaded" event:

1. Add the line Loaded="Page_Loaded" to your ContentPage XAML, like this:

   <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
        xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
        ...
        Loaded="Page_Loaded" 
   >
   

2. Add "Page_Loaded" event code to your page code-behind (.cs) file:

   private async void Page_Loaded(object sender, EventArgs e)
   {
    <Your code here>            
   }
   

I hope this helps.

You can override OnAppearing method in the .xaml.cs code of the page, and add a piece of code specified to OnAppearing. OnAppearing means that when the page appears, it will be called.

public partial class Page : ContentPage
{
    public Page()
    {
        InitializeComponent();
    }

   protected override void OnAppearing()
    {
        base.OnAppearing();
        //a piece of code specified
    }

}
