Currently hiding certain ticks requires custom empty tick template or custom ticktemplate selector. When resizing such slider labels get overlapped because tick panel reserves space for the ticks - to preserve the proportions between tick values.
So user needs to use Canvas in the datatemplate of the tick.
The idea of this feature request is to somehow allow such feature out of the box with eventually additional property / behavior / built-in selector etc.
Currently, the containers for the ticks are generated and added in the visual tree even when the TickPlacement is set to None. Think of an improvement so that in this case the ticks are not added in the visual tree.
Expose an easier approach for styling the buttons that are placed over the slider's track. For example Style properties. Those RepeatButtons have their x:Names set to "LargeIncreaseHandler" and "LargeDecreaseHandler". Currently, in order to modify their appearance (like Background for example) you will need to override the entire ControlTemplate of RadSlider.
Add the ability to align the RadSlider ticks when they are used in custom TickTemplate. The ticks are currenlly always top/left aligned depending on the slider orientation.
Add possibility to input value like in the sliders from MS Expresion Blend 's ColorPicker
