private void checkBox1_Checked(object sender, RoutedEventArgs e)
{
    if (checkBox1.IsChecked == false)
    {
        grid1.Visibility = System.Windows.Visibility.Hidden;
    }

    if (checkBox1.IsChecked == true)
    {
        grid1.Visibility = Visibility;
    }

}

为什么 grid1.Visibility = System.Windows.Visibility.Hidden;不工作，网格没有隐藏

您正在处理该Checked事件，该事件仅在 CheckBox 被选中时发生，而不是在未选中时发生。要解决此问题，请同时处理Unchecked事件：

private void checkBox1_Checked(object sender, RoutedEventArgs e) 
{ 
    grid1.Visibility = System.Windows.Visibility.Visible; 
} 

private void checkBox1_Unchecked(object sender, RoutedEventArgs e) 
{ 
    grid1.Visibility = System.Windows.Visibility.Hidden; 
}

当复选框不再被选中时，使用Unchecked事件得到通知。

试试这个，你必须使用折叠

private void checkBox1_Checked(object sender, RoutedEventArgs e)
{
        grid1.Visibility = System.Windows.Visibility.Visible;
}

private void checkBox1_UnChecked(object sender, RoutedEventArgs e)
{

        grid1.Visibility = System.Windows.Visibility.Collapsed;
}

试试这个代码

protected void checkBox1_Unchecked(object sender, RoutedEventArgs e)
 {
     grid1.Visibility = System.Windows.Visibility.Hidden;
 }

protected void checkBox1_Checked(object sender, RoutedEventArgs e)
  {
     grid1.Visibility = System.Windows.Visibility.Visible; 
  }

 private void checkBox1_CheckStateChanged(object sender, RoutedEventArgs e)
    {
        if (checkBox1.Checked)
        {
            grid1.Visibility = System.Windows.Visibility.Hidden;
        }else
        {
            grid1.Visibility = System.Windows.Visibility.Visible;
        }

    }

没有这样的属性 IsChecked。
