Wpf slider label
WPF Label Header:
I'm looking for a way to place labels alongside Slider Ticks. I don't think there is a direct way to do this. Not sure why Microsoft didn't provide this basic functionality.
How can I achieve this in WPF, perhaps using a dependency property.
The example slider code below shows the time interval, 1, 3, 6, 12, 24. I want these numbers to appear above / below the ticks. if I put the label anchor on the slider element as shown in the code snippet, the values will appear at the end of the slider, they are all packed together as comma separated values.
Any other way to display labels along ticks. I want this in WPF, perhaps by overriding the dependency property, not in code.
<Slider Name="ServiceTime"
Minimum="1"
Maximum="24"
Value="{Binding TimeInterval}"
TickPlacement="BottomRight"
IsSnapToTickEnabled="True"
Ticks ="{Binding TimeIntervalList}"
MinWidth="450"/>
<Label Content="{Binding ElementName=ServiceTime, Path=Value}"
VerticalAlignment="Center" Width="100" />

Right click on the slider -> Modify Template -> Edit Copy and Customize Thumb (create another template for the very thumb and add an extra shortcut, for example).
EDIT: This, for example, shows the current value of the slider on the label below the slider itself. The regular thumb canvas is moved to the stack bar. The mark is placed under the original thumb tracks and snaps to the slider. The value of the "parent" template. Although it only shows the actual value of the slider (as double), it might give you direction to get your own solution ...
