我正在开发Windows Phone 8.1 Silverlight应用程序。
我需要创建一个ListPicker并在全屏模式下将其打开，但始终会出错，因为不要在listpicker元素上检测到ExpansionMode。

我的构造函数页面函数：
public event_detail()
{
InitializeComponent();
String[] listProjects = {
"1º Projecto Drive",
"2º Projecto Drive 2º Projecto Drive",
"3º Projecto Drive",
"4º Projecto Drive",
"5º Projecto Drive",
"6º Projecto Drive",
"7º Projecto Drive",
"8º Projecto Drive",
"9º Projecto Drive",
"10º Projecto Drive",
"11º Projecto Drive",
};
foreach (var item in listProjects)
{
this.lpActivityType.Items.Add(item);
}
}
这些是错误：
错误1类型'ListPicker'中找不到属性'ExpansionMode'。 E：... \ event_detail.xaml 123 69 FlyGolf_V1
错误2成员“ ExpansionMode”无法识别或无法访问。 E：... \ event_detail.xaml 123 69 FlyGolf_V1
最佳答案
您需要添加toolkit:ListPicker
ItemTemplate="{StaticResource ListPickerItemTemplate}"
和
FullModeItemTemplate="{StaticResource ListPickerFullModeItemTemplate}"
如下
<toolkit:ListPicker x:Name="lpActivityType" ExpansionMode="FullScreenOnly" Foreground="#676a6c"
BorderBrush="#676a6c" Grid.Column="1" HorizontalAlignment="Center"
VerticalAlignment="Center" Width="320" Height="Auto"
ItemTemplate="{StaticResource ListPickerItemTemplate}"
FullModeItemTemplate="{StaticResource ListPickerFullModeItemTemplate}">
</toolkit:ListPicker>
还有这个如下
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Name="ListPickerItemTemplate">
<StackPanel Orientation="Horizontal" Background="White">
<TextBlock Text="{Binding}" Margin="0,0,0,0"
FontWeight="Normal" Foreground="Black" FontSize="18" />
</StackPanel>
</DataTemplate>
<DataTemplate x:Name="ListPickerFullModeItemTemplate">
<StackPanel Orientation="Horizontal">
<Grid Margin="0,0,0,0">
<TextBlock Margin="0,2,0,0" Text="{Binding}"
FontSize="22" TextWrapping="Wrap" Height="Auto" />
</Grid>
</StackPanel>
</DataTemplate>
</phone:PhoneApplicationPage.Resources
在
shell:SystemTray.IsVisible="True" Loaded="PhoneApplicationPage_Loaded">之后和<Grid>之前并添加.cs文件
lpActivityType.ItemsSource = listProjects.ToList();
关于c# - WP8 Listpicker不要进入完整模式，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/33349210/
