WPF-ListView项目在选定的更改上的字体大小 [英] WPF - ListView Item on Selected change Font size

问题描述

这是我的代码:

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <ListBox ItemsSource="{Binding Persons}">
        <ListBox.ItemContainerStyle>
            <Style TargetType="ListBoxItem">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                            <Border Background="White" BorderThickness="5" Name="Bd">
                                <Border.Style>
                                    <Style TargetType="Border">
                                        <Setter Property="BorderBrush" Value="White" />
                                    </Style>
                                </Border.Style>
                                <StackPanel Orientation="Horizontal" >
                                    <TextBlock Margin="10" Name="t1" Text="{Binding Name}"/>
                                    <TextBlock Margin="10" Text="{Binding Age}"/>
                                </StackPanel>
                            </Border>
                            <ControlTemplate.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter TargetName="Bd" Property="BorderBrush" Value="HotPink" />
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ListBox.ItemContainerStyle>

    </ListBox>
</Grid>

这是MouseOver的样子:

And this is how MouseOver looks like:

现在我想将鼠标悬停在上方以放大文本，该怎么办?

Now I want the Mouse over To enlarge the text, how can I do that ?

推荐答案

这样做吗?

<ControlTemplate.Triggers>
    <Trigger Property="IsMouseOver" Value="True">
        <Setter TargetName="Bd" Property="BorderBrush" Value="HotPink" />
        <Setter TargetName="t1" Property="FontSize" Value="72" />
    </Trigger>
</ControlTemplate.Triggers>

这将放大第一个文本块-您需要命名第二个文本块，并在TargetName属性中使用新名称创建另一个设置器，以同时放大这两个文本块.

This will enlarge the first textblock - you need to name the second one and make another setter with the new name in the TargetName property to enlarge both.
