密码错误时的登录错误
密码错误时的登录错误
提问于 2017-02-03 09:38:09
我在进入商店页面之前制作了应用程序，然后需要先登录。所以先检查一下。当它登录时，它可以直接导航到Store页面。但如果未登录，则用户必须登录，单击登录按钮后，将导航到"Store“页面。同样，如果您想导航到"Koleksi“页面。
我有一个问题，尽管有错误的密码，仍然可以登录和标题商店页面或"Koleksi“页面。当我添加导航到Store页面或"Koleksi“页面的功能时，就会发生这种情况。在添加该功能之前，如果密码错误，则无法登录。XAML：

因为您已经有了导航标志，所以当登录失败时，您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。
