用户控制的可见性

问题描述

在我的应用程序中有一个侧边栏，它包含这两个组件:

In my application got one sidebar, which is holding this two component :

        <Grid x:Name="AF" Visibility="Visibility">
            <betata:AForm Height="508" VerticalAlignment="Top"/>
        </Grid>
        <Grid x:Name="AN" Visibility="Collapsed">
            <betata:ANav Height="508" VerticalAlignment="Top"/>
        </Grid>

在 AForm 中使用此方法获得超链接按钮:

in the AForm got hyperlink button with this method :

    private void HyperlinkButton_Click(object sender, RoutedEventArgs e)
    {
        Visibility = Visibility.Collapsed;
        Sidebar sb = new Sidebar();
        sb.AN.Visibility = Visibility.Visible;
    }

但我不确定为什么 aForm 会折叠但 AN 无法显示.或者有没有其他解决方案可以实现::

but i not sure why the aForm will collapsed but AN could not become visible. or is there any other solution to implement ::

主页中的这一行调用UC_A ::

this line in main page to call up UC_A ::

<DWDS_LULCS_Views_Sidebar:Sidebar HorizontalAlignment="Left" Width="264"/>

• 主页控股
• 用户控件 A(边栏)控股
• 用户控制 B(管理员登录表单)和
• 用户控制 C(管理导航菜单)

UC_B默认可见，点击UC_B中的按钮调用UC_A的UC_C将可见性改为可见?

UC_B default is visible, and click the button in UC_B to call UC_A's UC_C change the visibility to visible ?

推荐答案

终于解决了这个问题...我就是这样的，在全局变量中做一些东西来验证是否要使其可见和折叠，然后给出一个侧边栏的事件处理程序(layout_updated).当我修改 UC_B 的可见性时，UC_A 将受到影响并且触发器将被调用.最后，UC_A 的 layout_updated 事件将改变 UC_C 的可见性变为可见.

Finally this problem is being solve... i do in this way, make something in global variable for verification whether which to make visible and collapse, then give one event handler to sidebar (layout_updated). when i modify the visibility of UC_B, UC_A will being affected and the trigger will be call. lastly, the UC_A's layout_updated event will change the visibility of UC_C become visible.
