如何修复 WPF 中的 Navigation/Frame 错误?错误#CS1061

How can I fix my Navigation/Frame Error in WPF? Error #CS1061

我正在尝试设置一个内部有框架的导航页面,但我遇到了这个错误,我似乎无法摆脱它。我的框架停止工作并显示我连接到它们的页面。

我已经尝试查找此错误 CS1061 并尝试查看错误所在。它似乎与 MainWindow.xaml 中的 Navigated="Frame_Navigated 冲突。也许任何人都可以指出我到底出了什么问题?以前用过。

MainWindow.xaml.cs代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace TataSteel_Gamification_01
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            //Display Items in Frame
            Loaded += Window_Loaded;

        }

        Boolean MenuToggle = true;

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //Open the Start Frame
            frame.NavigationService.Navigate(new Page1());
        }

        private void Btn_Page1_Click(object sender, RoutedEventArgs e)
        {
            //Open Page 1
            frame.NavigationService.Navigate(new Page1());
        }

MainWindow.xaml 代码(去掉不需要的部分):

<Window x:Name="ApplicationFrame" x:Class="TataSteel_Gamification_01.MainWindow"
        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"
        xmlns:local="clr-namespace:TataSteel_Gamification_01"
        mc:Ignorable="d"
        Title="MainWindow" Height="1200" Width="1920" Background="#FF1C2431">

<Grid x:Name="Grid_Display" ShowGridLines="False">

<Viewbox x:Name="Viewbox_Frame" Grid.Column="1" Grid.Row="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">

<Frame x:Name="frame" Content="Frame" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" NavigationUIVisibility="Hidden" Navigated="Frame_Navigated" Height="1170" Width="1435"/>

</Viewbox>

</Grid>

我希望之后的结果是导航再次工作,这样我就可以在框架内显示页面而不会出现任何错误。

Navigated="Frame_Navigated"

Frame_Navigated 是在您的框架实际导航时调用的函数。您似乎并没有在 MainWindow.xaml.cs

中实现它

这是您在 .cs 文件中缺少的内容:

private void Frame_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
 // your code to handle navigated frame
}
