问题描述

我使用的代码为：



将边界X：名称= QUOT;铬，QUOT; SnapsToDevicePixels = QUOT;真" Microsoft_Windows_Themes：ScrollChrome.ScrollGlyph =" {TemplateBinding Microsoft_Windows_Themes：ScrollChrome.ScrollGlyph}" Background =" {DynamicResource ScrollBarBrush}"余量= QUOT; 0，-3 QUOT;了borderThickness = QUOT 1 QUOT; />

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP ;&NBSP;&NBSP;&NBSP; < ControlTemplate.Triggers>

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; < Trigger Property =" IsMouseOver"值= QUOT;真">

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; < Setter Property =" Background"的TargetName = QUOT;铬，QUOT;值= QUOT; {DynamicResource
ScrollBarBrushHover}" />

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP ;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; < Setter Property =" BorderBrush"的TargetName = QUOT;铬，QUOT;值= QUOT; {DynamicResource
ScrollBarBrushSttokeHover}" />

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP ;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; < Setter Property =" Cursor"值= QUOT;手" />

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP ;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; < /触发>



我的列表框鼠标悬停但在这里，我也想加入<触发属性=" IsPressed"值= QUOT;真">&NBSP;哪个不起作用并且说："The member"IsPressed"无法识别或不能访问"

解决方案

我认为你在寻找什么为< EventTrigger RoutedEvent =" UIElement.MouseLeftButtonDown" />

I am using the code as:

<Border x:Name="Chrome" SnapsToDevicePixels="true" Microsoft_Windows_Themes:ScrollChrome.ScrollGlyph="{TemplateBinding Microsoft_Windows_Themes:ScrollChrome.ScrollGlyph}" Background="{DynamicResource ScrollBarBrush}" Margin="0,-3" BorderThickness="1" />
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="true">
                                <Setter Property="Background" TargetName="Chrome" Value="{DynamicResource ScrollBarBrushHover}"/>
                                <Setter Property="BorderBrush" TargetName="Chrome" Value="{DynamicResource ScrollBarBrushSttokeHover}"/>
                                <Setter Property="Cursor" Value="Hand"/>
                            </Trigger>

for my ListBox mouseover but here I also want to add <Trigger Property="IsPressed" Value="true">  which is not working and saying: "The member "IsPressed" is not recognized or is not accessible".

解决方案

I think what you're looking for is <EventTrigger RoutedEvent="UIElement.MouseLeftButtonDown"/>
