Question

我在进入商店页面之前创建了应用程序，然后需要先登录。所以先检查一下。登录后，它可以直接导航到商店页面。但是如果没有登录，用户必须登录，点击登录按钮后，它将导航到“商店”页面。同样，如果您想导航到“Koleksi”页面。

我遇到了问题，即使密码错误，仍然可以登录商店页面或“Koleksi”页面。当我添加导航到商店页面或“Koleksi”页面的功能时会发生这种情况。在添加功能之前，如果密码错误，则无法登录。 XAML：

LocalBroadcastManager.getInstance(this).unregisterReceiver(br);

代码：

                <Image x:Name="bukukoleksi" HorizontalAlignment="Center" Width="150" Height="150" Margin="20,0,0,0" VerticalAlignment="Center" Tapped="koleksi_Tapped" Source="images/new icon/bse-icon300-w8-KOLEKSI.png"/>

由于您已经拥有导航标记，因此在登录失败时也可以将它们设置为false。在这种情况下，当登录失败时，它将无法导航。例如：

 //Your code
  catch (HttpRequestException ex)
  {
      //ConnectionException();
      loadingLogin.IsActive = false;
  }
  //Add following code
  if (loadingLogin.IsActive == false)
  {
      isstoreTapped = false;
      iskoleksiTapped = false;
  }

将此代码块添加到ProcessLogin()方法的最后一个。
