  • You want to access the Entry value in the code, that’s it?

To access the value of your Entry, you can do the following:

<Entry 
    x:Name="txtValue"
    Keyboard="Numeric"/>

Note that I used the property x:Name to set a name for your Entry. By doing this, you can now access the element in your code.

namespace App4
{
    public partial class MainPage : ContentPage
    { 
        public MainPage()
        {
            InitializeComponent();
        }

        private async void Handle_Clicked (object sender,  System.EventArgs e)
        {
           // Valor do Entry
           var value = txtValue.Text;

           await Navigation.PushAsync(new Page1());
        }
    }
}

To convert the value to double, you can do it:

double newValue = Double.Parse(value);

To convert the value to decimal, you can do it:

decimal newValue = Decimal.Parse(value);
