我正在写一个
Windows Phone 8.1应用程序(WinRT).
我的用户控件：
XAML：
<UserControl x:Name="LoadingProgressBarPage"
x:Class="Project1.Custom.General.UserControls.LoadingOverlayFullScreen"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Merakyahoga.com.Custom.General.UserControls"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
Foreground="{x:Null}"
d:DesignHeight="800" d:DesignWidth="480" >
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<StackPanel
Name="LayoutRoot_StackPanelMain"
Grid.Row="1"
Orientation="Vertical">
<ProgressBar Name="ProgressBar"
IsIndeterminate="True"
Foreground="{StaticResource DefaultTheme_DarkBlueColor}"
Height="50"
Width="480"
VerticalAlignment="Center"/>
<StackPanel Name="LayoutRoot_SubStackPanel"
Orientation="Horizontal"
HorizontalAlignment="Center"
VerticalAlignment="Center">
<Image Name="ImageHolder_Main"
Width="54">
</Image>
<TextBlock Name="ProgressBarText"
Text="Please Wait.."
Margin="10,0"
FontWeight="Normal"
HorizontalAlignment="Center"
FontSize="18"
Foreground="{StaticResource DefaultTheme_DarkBlueColor}" VerticalAlignment="Center"/>
</StackPanel>
</StackPanel>
</Grid>
CS：
namespace Project1.Custom.General.UserControls
{
public partial class LoadingOverlayFullScreen : UserControl
{
public LoadingOverlayFullScreen()
{
InitializeComponent()
//WINRT:
this.LayoutRoot.Height = Window.Current.Bounds.Height;
this.LayoutRoot.Width = Window.Current.Bounds.Width;
}
}
}
在我的mainpage.cs中：
LoadingOverlayFullScreen LoadingOverlayFullScreenObject = new LoadingOverlayFullScreen();
//test:
LoadingOverlayFullScreenObject.ProgressBarText = "Hello"; //ERROR Here >> **element inaccessible due to its protection level**
解决方法
通过命名TextBlock元素,可以使XAML编译器生成具有该名称的类成员,即ProgressBarText.但该成员的可访问性不是公开的,而是内部的.
如果您确实希望该字段是公共的,则可以添加x：FieldModifier属性：
<TextBlock Name="ProgressBarText"
x:FieldModifier="public"
Text="Please Wait.."
Margin="10,0"
FontWeight="Normal"
HorizontalAlignment="Center"
FontSize="18"
Foreground="{StaticResource DefaultTheme_DarkBlueColor}"
VerticalAlignment="Center"/>
也就是说,最好将TextBlock对象的Text属性公开为代码隐藏中的字符串属性.或者甚至更好,使用数据绑定来控制TextBlock的Text值(但是你的代码示例不够完整,我不能说你将如何做到这一点).
