由 [亡魂溺海] 提交于 2020-01-03 16:53:15
问题 Ok, here is my scrollbar style. <Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}"> <Setter Property="Background" Value="#D5E0FF" /> </Style> If I apply this, all scrollbars in my application will get affected, undoubtedly. Now I have 2 listview(s) in my application, I need to apply this style to only a particular listview, while another one remain default scrollbar, any idea? This is driving me crazy. Thanks. 回答1: Add the style as a resource to the ListView itself. <ListView>
