将鼠标悬停在WPF中的列表框中选择项目 [英] Mouseover to select item in listbox in WPF

问题描述

我对WPF比较陌生，但是我想知道如何启用列表框以基于鼠标悬停事件而不是单击按钮来选择项目.我希望将鼠标悬停在所选项目上时选择该项目，而无需先按一下.

I am relatively new to WPF, but I would like to know how can I enable a listbox to select an item based on a mouseover event instead of the button click. I would like the item to be selected when the mouse is over the selected item, without having to press click first.

谢谢

推荐答案

您可以在设置IsSelected属性的IsMouseOver属性上编写带有触发器的简单ListBoxItem样式:

You may write a simple ListBoxItem Style with a Trigger on the IsMouseOver property that sets the IsSelected property:

<ListBox>
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="IsSelected" Value="True"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>
