单击按钮可折叠列表框中的详细信息

问题描述

我正在尝试做这样的事情：当你点击按钮时，listboxitem会折叠并显示一些额外的信息：



[]



我已经做了类似的事情：细节是单击整个项目项时显示。任何想法如何修改这种风格，只有点击按钮（或它附近）才会发生折叠？

I'm trying do make something like this: when you click the button, the listboxitem collapses and shows some additional information:

I have already made something similar: details are showed when the whole item item is clicked. Any ideas how to modify this style so collapsing will take place only if the button (or near it) is clicked?

<Style x:Key="collapsingGridStyle" TargetType="{x:Type Grid}">
            <Style.Triggers>
                <DataTrigger
                   Binding="{Binding
                                Path=IsSelected,
                                RelativeSource=
                                {
                                    RelativeSource
                                    Mode=FindAncestor,
                                    AncestorType={x:Type ListBoxItem}
                                }
                        }"
                    Value="False">
                    <Setter Property="Grid.Visibility"
                    Value="Collapsed"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
