UWP按钮无法正确重绘

时间：2018-10-06 12:16:48

标签： c# xaml button uwp

因此，我在测试UWP应用程序时，发现按钮和条件格式有些奇怪。

该应用会查看当天的内容，并根据当天确定要显示的按钮。

如果不是所讨论的日期，则显示以下内容： https://firebase.google.com/docs/firestore/manage-data/transactions?authuser=1#batched-writes

但是如果我回去并将日期更改为符合条件的适当日期，则会显示以下内容：

如果我在进入有问题的页面之前已经选择了正确的条件日，那么我将获得正确的格式： enter image description here

有什么想法吗？

XAML代码段：

我知道了。我自己做的我最初在页面中间设置了这两个按钮，所以我修改了它们的边距，但是我使用了不同的数字。 

        public void MechanicalPenthouseButtons()
        {
            if(App.Day == "Tue")
            {
                SignInButtonStatus();
                AHU1A2B7AButton.Visibility = Visibility.Visible; //Button 1
                AHU2B3C4D9C10DButton.Visibility = Visibility.Visible; //Button 2
                AHU4D5E6RButton.Visibility = Visibility.Visible; //Button 3
                MainPenthouseButton.Visibility = Visibility.Visible; //Button 4
                CHWPButton.Visibility = Visibility.Visible; //Button 5
                AHU13A14B15CButton.Visibility = Visibility.Visible; // Button 6
                AHU15C16D17E21C22DButton.Visibility = Visibility.Visible; // Button 7
                AHU17E18R24RButton.Visibility = Visibility.Visible; // Button 8
                AHURoom3020Button.Visibility = Visibility.Visible; // Button 9
                AHU22D23E24RButton.Visibility = Visibility.Visible; // Button 10

                AHU7A8B9CButton.Visibility = Visibility.Visible; //Button 13
            }
            else
            {
                SignInButtonStatus();
                CHWPButton.Visibility = Visibility.Visible; //Button 5
                CHWPButton.Margin = new Thickness(50, 10, 45, 10); // Was (50,10,0,0)
