Question

我正在尝试在新的WP7应用程序中实现TimePicker。但是当我运行应用程序时...... 始终存在错误：

'无效的属性值控件：属性TargetType'的LongListSelector

这是我的xaml代码

                    <TextBlock TextWrapping="Wrap" Text="Address" Foreground="{StaticResource PhoneSubtleBrush}" />
                    <TextBox TextWrapping="Wrap" Text="TextBox"/>
                </StackPanel>
            </StackPanel>
            <StackPanel HorizontalAlignment="Left" Height="100" VerticalAlignment="Bottom" Width="400" Margin="36,0,0,8" Orientation="Horizontal">

                <Button Content="Cancel" Width="200" Height="80"/>
            </StackPanel>
        </Grid>
    </Grid>
</phone:PhoneApplicationPage>

顺便说一下，我添加了“Microsoft.Phone.Controls.Toolkit.dll”

您发布了错误的XAML。我们需要用于控制的XAML。

无论如何，错误消息表示您试图在Value上设置LongListSelector属性。 <{1}}控件不公开这样的依赖属性，因此您无法设置它。
