Question

我试图获得一个按钮（点击时）以显示隐藏的单选按钮rbChoice2.Visibility = Visibility.Visible。单选按钮位于另一个窗口上，需要另一个按钮save_Click来显示窗口并向单选按钮内容发送一个值。所以我需要第一个按钮，在单击save_Click之前已经使单选按钮可见。

我对WPF很新，虽然我已经尝试将可见性代码和内容代码放在第一个按钮中，但它不起作用。这是我尝试过的代码。

public partial class Create : Window
{

    public Create()
    {
        InitializeComponent();
    }

    private void addChoice1_Click(object sender, RoutedEventArgs e)
    {
        choice2.Visibility = Visibility.Visible;
        addChoice2.Visibility = Visibility.Visible;
        addChoice1.Visibility = Visibility.Hidden;
        Save obj = new Save();
        obj.rbChoice2.Visibility = Visibility.Visible;
        obj.rbChoice2.Content = choice2.Text;


    }

    private void save_Click(object sender, RoutedEventArgs e)
    {

        Save objS = new Save();
        objS.lbTest.Content = question.Text;
        objS.rbChoice1.Content = choice1.Text;
        objS.rbChoice2.Content = choice2.Text;
        objS.ShowDialog();

    }

}

这是一张照片：As the Add Choice button is clicked, another textbox is made visible under the first one and so at the same time another radio button should be made visible in the Save window but it doesn't work.

我在编码时学习xaml，所以我希望我能正确地提出这个问题。真的希望有人可以帮忙解决这个问题。非常感谢

你有2个窗口副本 - ＆＃34; obj＆＃34;和＆＃34; objS＆＃34;根本没有关系。

试试这个：

public partial class Create : Window
{

public Create()
{
    InitializeComponent();
}

Save obj = new Save();

private void addChoice1_Click(object sender, RoutedEventArgs e)
{
    choice2.Visibility = Visibility.Visible;
    addChoice2.Visibility = Visibility.Visible;
    addChoice1.Visibility = Visibility.Hidden;

    obj.rbChoice2.Visibility = Visibility.Visible;
    obj.rbChoice2.Content = choice2.Text;
}

private void save_Click(object sender, RoutedEventArgs e)
{
    obj.lbTest.Content = question.Text;
    obj.rbChoice1.Content = choice1.Text;
    obj.rbChoice2.Content = choice2.Text;
    obj.ShowDialog();
}

}

在窗口显示xaml之前执行操作的按钮
