如何在WPF Expander中隐藏标题？

I have a business requirement that when the user clicks a series of checkboxes in a WPF application that it will show panels depending upon what checkboxes they select. I would like to use the expander panel but I am not sure how to hide the header. The user should not be allowed to see it unless they check the checkbox. Does anyone know?

我有一个业务要求,当用户单击WPF应用程序中的一系列复选框时,它将显示面板,具体取决于他们选择的复选框。我想使用扩展器面板,但我不知道如何隐藏标头。除非他们选中复选框,否则不应允许用户查看它。有人知道吗?

You can do this via making a custom Style for your Expander.

您可以通过为扩展器创建自定义样式来完成此操作。

However, it might be easier to just place the controls in a different panel, and set it's visibility to Collapsed in response to the check box state. The main reason to use Expander is specifically to have the header and controls.

但是,将控件放在不同的面板中可能更容易,并将其可见性设置为Collapsed以响应复选框状态。使用Expander的主要原因是具有标题和控件。

While not the ideal approach you could go this route...

虽然不是理想的方法,你可以走这条路......

    <Expander>
        <Expander.Header>
            <TextBlock Visibility="{Binding IsExpanded, RelativeSource={RelativeSource AncestorType={x:Type Expander}, Mode=FindAncestor}, 
                 Converter={StaticResource BoolToVisibilityConverter}}">My Expander</TextBlock>
        </Expander.Header>
    </Expander>

...where BoolToVisibilityConverter is something like...

...... BoolToVisibilityConverter就像......

    public class BoolToVisibilityConverter : IValueConverter
    {
        #region IValueConverter Members

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if ((bool)value)
                return Visibility.Visible;
            return Visibility.Collapsed;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if ((Visibility)value == Visibility.Visible)
                return true;
            return false;
        }

        #endregion
    }

This answer has all that you need: WPF Expander Button Styled so it is inside Expander Header

这个答案有你需要的所有东西:WPF扩展器按钮样式,所以它在扩展器标题内

If you use the style he mentions and set no header content, the header disappears

如果你使用他提到的样式并且没有设置标题内容,则标题会消失
