如何訪問WPF派生UserControl中的成員控件

Question

我有一個基於Windows手機的控件，並且想從其中獲取其他Windows手機UserControl。

當我把衍生代碼，並試圖從派生類訪問其他控件，我得到一個錯誤：

The name 'LocationConsent_CheckBox' does not exist in the current context 
<path>\project\RML\RML\CtrlLocServ.xaml.cs 

基地UserControl XAML：

<UserControl x:Class="RML.CtrlBase" 
      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" 
      d:DesignHeight="300" d:DesignWidth="300"> 
    <Grid x:Name="LayoutRoot"> 
    </Grid> 
</UserControl> 

基地UserControl後面的代碼：

namespace RML 
{ 
    public partial class CtrlBase : UserControl 
    { 
     public CtrlBase() 
     { 
        InitializeComponent(); 
        LayoutRoot.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Transparent); 
     } 
    } 
} 

派生UserControl xaml： （注意我已經改變了電網的名稱LayoutRoot2而不是LayoutRoot）

<src:CtrlBase x:Class="CtrlLocServ" 
      xmlns:src="clr-namespace:RML" 
      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" 
      d:DesignHeight="300" d:DesignWidth="300"> 
    <Grid x:Name="LayoutRoot2"> 
     <StackPanel> 
      <CheckBox x:Name="LocationConsent_CheckBox" /> 
     </StackPanel> 
    </Grid> 
</src:CtrlBase> 

衍生UserControl，後面的代碼：

namespace RML 
{ 
    public partial class CtrlLocServ : CtrlBase 
    { 
     public CtrlLocServ() 
     { 
      InitializeComponent(); 
      LocationConsent_CheckBox.IsChecked = false; 
     } 
    } 
} 

這仍然給我上面的錯誤雖然。

下面是生成的文件：

#pragma checksum "..\..\CtrlLocationService.xaml" "{406ea660-64cf-4c82-b6f0-42d48172a799}" "D56B477B354FB03C45E5F49343F67196"

建議將不勝感激。

變化：

<UserControl x:Class="CtrlLocationService" 
xmlns:src="clr-namespace:RML.Controls" 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
mc:Ignorable="d" 
FontFamily="{StaticResource PhoneFontFamilyNormal}" 
FontSize="{StaticResource PhoneFontSizeNormal}" 
Foreground="{StaticResource PhoneForegroundBrush}" 
d:DesignHeight="300" d:DesignWidth="480"> 

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}"> 

    <StackPanel Grid.Row="0" Margin="10,0,10,0"> 
     <CheckBox 
      x:Name="LocationConsent_CheckBox" 
      Content"test" 
      Checked="Location_Checked" 
      Unchecked="Location_Unchecked" /> 

    </StackPanel> 

</Grid> 

</UserControl> 

到：

<src:CtrlBase x:Class="CtrlLocationService" 
xmlns:src="clr-namespace:RML.Controls" 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
mc:Ignorable="d" 
FontFamily="{StaticResource PhoneFontFamilyNormal}" 
FontSize="{StaticResource PhoneFontSizeNormal}" 
Foreground="{StaticResource PhoneForegroundBrush}" 
d:DesignHeight="300" d:DesignWidth="480"> 

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}"> 

    <StackPanel Grid.Row="0" Margin="10,0,10,0"> 
     <CheckBox 
      x:Name="LocationConsent_CheckBox" 
      Content"test" 
      Checked="Location_Checked" 
      Unchecked="Location_Unchecked" /> 

    </StackPanel> 

</Grid> 

</src:CtrlBase> 

如果你想有其他的基本用戶的控制，你必須同時在後面的代碼和XAML

改變基地仍然在工作，當我得到的工作代碼，我會更新

這是在我的工作簡單的文本示例。您可以嘗試訪問https://onedrive.live.com/?cid=b37cc7d5117b9a1b&id=B37CC7D5117B9A1B!27341並檢查項目和生成文件中的差異。
