WPF 中 通过点击ListBox中的元素自动选中一整项
由于WPF中,经常有个问题点击Listbox中的里面的元素经常不会选中某项,选中的项也不会变颜色,这个其实可以通过修改样式去实现。
<Style TargetType="{x:Type ListBoxItem}"> <Setter Property="SnapsToDevicePixels" Value="True" /> <Setter Property="FocusVisualStyle" Value="{x:Null}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <Border Name="Border" Padding="1 1 1 1" Background="Transparent" SnapsToDevicePixels="True" CornerRadius="20"> <ContentPresenter /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="Border" Property="Background" Value="#D84E20" /> <Setter Property="Foreground" Value="White" /> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Foreground" Value="White" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsKeyboardFocusWithin" Value="true"> <Setter Property="IsSelected" Value="true" /> </Trigger> <EventTrigger RoutedEvent="PreviewGotKeyboardFocus"> <BeginStoryboard> <Storyboard> <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="(ListBoxItem.IsSelected)"> <DiscreteBooleanKeyFrame KeyTime="0" Value="True" /> </BooleanAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </Style.Triggers> </Style>
