title: How to set a text in TextBlock.
body: <p>How to set a text in textblock defined xaml using c#. I am redirecting to a phone page where I have a stackpanel and couple of textblocks inside.

Basically the textblock in not recognised... How to make it visible in c# code...</p>
  
  <p>XAML:</p>
  
  <pre><code>&lt;Grid x:Name="ContentPanel" Grid.Row="1" Margin="16,0,12,0"&gt;
      &lt;StackPanel x:Name="activationPanel" Margin="0,10"&gt;
          &lt;TextBlock TextWrapping="Wrap" Text="Almost there !" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070"/&gt;
          &lt;TextBlock TextWrapping="Wrap" Text="An activation mail has been sent" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070" Margin="0,18,0,0"/&gt;
          &lt;TextBlock Name="useremail" TextWrapping="Wrap" FontFamily="Segoe UI" FontWeight="SemiBold" FontSize="24" Foreground="#FF486070" Margin="0,10,0,0" LostFocus="useremail_LostFocus"/&gt;
          &lt;TextBlock TextWrapping="Wrap" Text="please click on the link to activate your account" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070" Margin="0,50,78,0"/&gt;
          &lt;Button x:Name="btnAcA" Content="ACCOUNT ACTIVATED" Width="335" HorizontalAlignment="Left" Height="42" Padding="12,0,10,0" Background="#FF55D782" BorderBrush="{x:Null}" BorderThickness="0" FontSize="16" FontFamily="Segoe UI" Style="{StaticResource LoginButtonStyle}" Margin="0,90,0,25" Click="btnAcA_Click"/&gt;

      &lt;/StackPanel&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>C#:</p>
  
  <pre><code>protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
  {
      base.OnNavigatedTo(e);
      string email=null;
      if (this.NavigationContext.QueryString.ContainsKey("email"))
      {
          email = this.NavigationContext.QueryString["email"];
      }
  
      Debug.WriteLine(email);
      setTextBoxValue(email);
  }
  
  private void setTextBoxValue(string email)
  {
      //TextBlock useremail = new TextBlock();
      useremail.Text = email;
  }
  </code></pre>
