我目前有两个用户控件,分别是UC1和UC2。我有一个主窗口。在应用程序启动时,用户可以看到UC1。当用户单击UC1中的按钮时,UC1应该消失并且UC2应该显示在同一窗口中。我尝试了以下方法:
MainWindow.xaml
<Window x:Class="Test.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d" xmlns:my="clr-namespace:Test" WindowState="Maximized">
<Grid>
<my:UC1 />
<my:UC2 Visibility="Collapsed"/>
</Grid>
最初,两个UC都在同一时间可见,因此我使UC2折叠了。现在,我想在单击UC1中的按钮时再次使其可见。我无法从UC1访问UC2的可见性。
UC1.xaml.cs
private void button2_click(object sender, MouseButtonEventArgs e)
{
this.Visibility = System.Windows.Visibility.Collapsed;
// What to write here?
}

对于2个控制器UC1和UC2,使用Tag属性可以正常工作。现在,我添加了另一个控制器UC3,该控制器仅在单击其他按钮后可见。
所以,最后我有了UC1,UC2和UC3,其中只有UC1可见。 UC1有两个按钮,一个单击第一个按钮,只有UC2应该可见,而单击第二个按钮,只有UC3应该可见。
我无法绑定多个标签。有多个标签转换器吗?
最佳答案

发布整个代码以使答案更加清晰。而且我也没有任何例外。
