UI元素对x:Name不可见，它们只对Name可见.如何修复

我无法从使用x:Name的代码访问UI元素。它们只有在我使用简单的Name时才可用。我需要通过x:Name恢复访问，因为必须使用FindName方法。这个项目是在我开始工作之前创建的，这就是为什么我不知道之前可能会出错的原因。

在窗口的顶部有如下的命名空间:

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

同样，我认为代码隐藏是自动生成的，因为它有以下消息:

此代码和信息由自动代码生成器生成

我需要访问图钉。我添加了x:Name="push1"。但是在代码后面是不可见的。

<maps:Map ZoomLevel="18" Height="575" Center="{Binding CurrentTopIssuesSchema.Coords, TargetNullValue=null}" Name="map1" Width="415" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,-10,0">
    <toolkit1:MapExtensions.Children>
        <toolkit1:Pushpin x:Name="push1" Background="{Binding CurrentTopIssuesSchema.StatusColor}" GeoCoordinate="{Binding CurrentTopIssuesSchema.Coords, TargetNullValue=null}" Content="{Binding CurrentTopIssuesSchema.Name}" ContentTemplate="{StaticResource Template_Content}">
        </toolkit1:Pushpin>
    </toolkit1:MapExtensions.Children> 
</maps:Map>

以下是来自XAML的名称空间:
