Xamarin MVVM passing data to other view

Question

I want to pass the data to another view page. So far I can get the data I need to pass. My problem is how do I pass the data in MVVM. I used Application.Current.MainPage.Navigat

Answer 1

If you want to send the int. First declare that in your DatabaseSyncPage Like below

public partial class DatabaseSyncPage : ContentPage
{
    public DatabaseSyncPage( int Id)
    {
    }
}

& when you are pushing your page in your code else block do like this

if (content.Equals("[]") || string.IsNullOrWhiteSpace(content) || string.IsNullOrEmpty(content))
{
    MessagingCenter.Send(this, "Http", Username);
}
else
{
    var result = JsonConvert.DeserializeObject<List<LoggedInUser>>(content);
    var contactId = result[0].ContactID;
    Application.Current.MainPage.Navigation.PushAsync(new DatabaseSyncPage(contactId), true);
}

Answer 2

I'm assuming that contactID is an int.

Create an additional constructor in your DatabaseSyncPage:

public DatabaseSyncPage (int contactID)
{
    // TODO: Do something with your id
}

But this passes the data to the page, not the page model. Are you using any kind of framework? It would probably be worth looking into that.

You can use xamrin.plugins.settings nuget package.
