The ListViewItem style cant trigger Unselected but can trigger Selected.
I want to see someThing showed when the listView item be selected and hid when unselected.
But I can see that it was shown, but could not see it being hidden.
I copy the style from https://msdn.microsoft.com/en-us/library/windows/apps/mt299136.aspx
And I sure I set the SelectionMode is Single.
The code that I copy from is
<Style x:Key="ListViewItemStyle" TargetType="ListViewItem">
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
<Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
<Setter Property="Background" Value="{ThemeResource ListViewItemBackground}"/>
<Setter Property="Foreground" Value="{ThemeResource ListViewItemForeground}"/>
<Setter Property="TabNavigation" Value="Local"/>
<Setter Property="IsHoldingEnabled" Value="True"/>
<Setter Property="Padding" Value="12,0,12,0"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="MinWidth" Value="{ThemeResource ListViewItemMinWidth}"/>
<Setter Property="MinHeight" Value="{ThemeResource ListViewItemMinHeight}"/>
<Setter Property="AllowDrop" Value="False"/>
<Setter Property="UseSystemFocusVisuals" Value="True"/>
<Setter Property="FocusVisualMargin" Value="0"/>
<Setter Property="FocusVisualPrimaryBrush" Value="{ThemeResource ListViewItemFocusVisualPrimaryBrush}"/>
<Setter Property="FocusVisualPrimaryThickness" Value="2"/>
<Setter Property="FocusVisualSecondaryBrush" Value="{ThemeResource ListViewItemFocusVisualSecondaryBrush}"/>
<Setter Property="FocusVisualSecondaryThickness" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Grid>
<ContentPresenter ></ContentPresenter>
<Button x:Name="b" Opacity="0"></Button>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselecting">
<Storyboard BeginTime="0:0:0">
<DoubleAnimation Storyboard.TargetName="b"
Storyboard.TargetProperty="Opacity"
Duration="0:0:0.1"
To="0" />
</Storyboard>
</VisualState>
<VisualState x:Name="Unselected">
<Storyboard BeginTime="0:0:0">
<DoubleAnimation Storyboard.TargetName="b"
Storyboard.TargetProperty="Opacity"
Duration="0"
To="0" />
</Storyboard>
</VisualState>
<VisualState x:Name="Selected">
<Storyboard BeginTime="0:0:0">
<DoubleAnimation Storyboard.TargetName="b"
Storyboard.TargetProperty="Opacity"
Duration="0"
To="1" />
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I have seen this answer https://stackoverflow.com/a/36010296/6116637 that Archana offered a way that use CustomUnselected and change it when SelectionChanged.
It's a good way but I dont want to write the same code to lot of place for I have many ListView should do it.Are there any good way to do it only write xaml?
I have seen the answer that say binding to IsSelected but the TemplateBinding cant do it when I want to Visibility for the TemplateBinding cant use convert.
And when I use the Visibility="{Binding Path={TemplateBinding IsSelected},Converter={StaticResource BooleanVisibility},Mode=OneWay}"
or Visibility="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsSelected,Converter={StaticResource BooleanInverseVisibility},Mode=OneWay}"
, the result is not what I want.
