                Margin="10"
                Name="BGrid">
            </Grid>

            <Grid

            </Grid>

            <Grid
                Background="White" 
                Margin="10"
                Name="WGrid">
            </Grid>

            <Grid 
                Background="Yellow"
                Margin="10"
                Name="YGrid">
            </Grid>

            <Grid 
                Background="Pink" 
                Margin="10"
                Name="PGrid">
            </Grid
        </Grid>
   </Grid>
</Window>

这是我的C＃代码。

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 SampleWpf
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Button RButton, GButton, BButton, WButton, YButton, PButton;
            Grid RGrid,GGrid, BGrid, WGrid, YGrid, PGrid;
        }
        public void RedClick(object sender, RoutedEventArgs e)
        {

            RGrid.Visibility = Visibility.Visible;
        }
        public void GreenClick(object sender, RoutedEventArgs e)
        {

        }
        public void BlueClick(object sender, RoutedEventArgs e)
        {

        }
        public void WhiteClick(object sender, RoutedEventArgs e)
        {

        }
        public void YellowClick(object sender, RoutedEventArgs e)
        {

        }
        public void PinkClick(object sender, RoutedEventArgs e)
        {

        }
    }
}

当我点击按钮时，我想打开一个红色的网格。

Answer 1

从您的代码中删除Grid和Button对象（C＃），因为您已经在XAML中拥有它们。

MainWindow类是一个部分类，它分布在您的C＃代码和XAML的编译输出中。因此，您仍然可以从C＃代码中引用RGrid等，就好像您已在同一文件中声明它一样。

它应该适合你。

网格可从多个网格中看到
