Hello Naveen,

Try this for textbox:

<TextBox x:Name="txt1" Width="300" TextChanged="txt1_TextChanged_1"/>

  private void txt1_TextChanged_1(object sender, TextChangedEventArgs e)
        {
Debug.WriteLine("text changed");
        }

Try this for textblock, it fires 2 times, when your page is loaded & when your textvalue change :

<TextBlock x:Name="tbl1" Text="sample" Width="125" VerticalAlignment="Center" FontSize="15" SizeChanged="tbl1_SizeChanged_1" />

code:

  private void tbl1_SizeChanged_1(object sender, SizeChangedEventArgs e)
        {
Debug.WriteLine("text changed");
        }

protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            tbl1.Text = "test";
        }
