我有一个最小 0 和最大 100 的滑块。
当我将鼠标悬停在滑块上时,我有一个可见的弹出窗口。
目前,我将弹出窗口与滑块值绑定。
我想要的是:
当我将鼠标移到滑块上时,我想看到假设在那个位置的值。
例如:
我的 XAML:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
Title="MainWindow" WindowStyle="None" Width="1920" Height="1080" WindowState="Maximized" KeyboardNavigation.TabNavigation="None" Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="bla" MouseMove="Rectangle_MouseMove" MouseLeave="Rectangle_MouseLeave" IsMoveToPointEnabled="True" HorizontalAlignment="Left" Width="542" VerticalAlignment="Top" Margin="116,839,0,0" Value="0" Style="{DynamicResource SliderStyle1}" Height="66" AutoToolTipPrecision="0" AutoToolTipPlacement="TopLeft"/>
<Popup Name="floatingTip" AllowsTransparency="True" Placement="Relative" PlacementTarget="{Binding ElementName=bla}">
<Border BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Text="{Binding ElementName=bla, Path=Value}"></TextBlock>
</Border>
</Popup>
</Grid>
</Window>
