How to access a data Which I entered at a Entry tab on other page?

BalaVelan

I am a beginner . I want to to get a data from
page1.xaml

and access this data at other .xaml pages like page3.xaml and page 5.xaml.

Here the data I get in 'X:Name= "EntryText1"' will automatically shown in 'X:Name="EntryText3"' . please tell me, What can I do.

Page1.xaml:

    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="NSF_app.setting">

<StackLayout BackgroundColor="White" ">

    <Entry x:Name="EntryText1"/>

</StackLayout>

page1.xaml.cs:

public partial class page1: ContentPage
{
public page1()
 {
 InitializeComponent();
 }
}

page3.xaml:

     <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="NSF_app.setting">

<StackLayout BackgroundColor="White" ">

    <Entry x:Name="EntryText2"/>
    <Entry x:Name="EntryText3"/>
    <Entry x:Name="EntryText4"/>
</StackLayout>

page3.xaml.cs:

       public partial class page3: ContentPage
{
public page3()
 {
 InitializeComponent();
 }
}

You can create a public static value to store the entry's value, when entry's text changed event was executed, set the new value to the EntryValue.

  public static string EntryValue = "";
        private void EntryText1_TextChanged(object sender, TextChangedEventArgs e)
        {
            EntryValue = e.NewTextValue;
        }

In the page1's xaml. You should achieve the TextChanged event like following code.

<Entry x:Name="EntryText1" TextChanged="EntryText1_TextChanged" />

In the page3, you can get the value and set it by following code.

 public Page3()
        {
            InitializeComponent();

            EntryText2.Text = Page1.EntryValue;
        }
