Gets or sets whether a tooltip that contains the current value of the RadSlider displays when the Thumb is pressed. If a tooltip is displayed, this property also specifies the placement of the tooltip.

Declaration
public AutoToolTipPlacement AutoToolTipPlacement { get; set; }
Property Value
AutoToolTipPlacement

DecreaseHandleStyle

Gets or sets the style for the Decrease Repeat button used internally by the slider.

Declaration
public Style DecreaseHandleStyle { get; set; }
Property Value
System.Windows.Style

Delay

Gets or sets the Delay property of the Increase and Decrease handles.

Declaration
public int Delay { get; set; }
Property Value
System.Int32

Remarks

Each click on any of the handles increases/decreases the value by the amount that is set to the System.Windows.Controls.Primitives.RangeBase.SmallChange property.

EnableSideTicks

Gets or sets a value indicating whether side ticks are enabled.

Declaration
public bool EnableSideTicks { get; set; }
Property Value
System.Boolean

True if side ticks are enabled; otherwise, false.

HandlesVisibility

Gets or sets the Visibility property of the Increase and Decrease handles.

Declaration
public Visibility HandlesVisibility { get; set; }
Property Value
System.Windows.Visibility

Remarks

Each click on any of the handles increases/decreases the value by the amount that is set to the System.Windows.Controls.Primitives.RangeBase.SmallChange property.

IncreaseHandleStyle

Gets or sets the style for the Increase Repeat button used internally by the slider.

Declaration
public Style IncreaseHandleStyle { get; set; }
Property Value
System.Windows.Style

IsDeferredDraggingEnabled

Gets or sets a value that indicates whether the content is stationary when the user drags the Thumb of RadSlider. This is dependency property.

Declaration
public bool IsDeferredDraggingEnabled { get; set; }
Property Value
System.Boolean

IsDirectionReversed

Gets or sets the direction of increasing value. This is a dependency property.

Declaration
public bool IsDirectionReversed { get; set; }
Property Value
System.Boolean

Remarks

The value of this property determines the direction of increasing value of a RadRadSlider.

For example, when you move the thumb control up on a vertical RadSlider when the IsDirectionReversed property is set to false, the Value of the RadSlider increases. If the value of the IsDirectionReversed property is changed to true, the System.Windows.Controls.Primitives.RangeBase.Value of the RadSlider decreases as the thumb moves up.

IsMouseWheelEnabled

Gets or sets whether the wheel of the mouse can be used for sliding the thumb. This is dependency property.

Declaration
public bool IsMouseWheelEnabled { get; set; }

Declaration
public bool IsMoveToPointEnabled { get; set; }
Property Value
System.Boolean

Remarks

When this property is set to false and a mouse click occurs along the RadSlider away from the thumb, the thumb moves in the direction of the mouse click. Instead of moving immediately to the mouse click location, the thumb moves a distance that is defined by the RepeatInterval property for each mouse click. The effect of multiple mouse clicks can be emulated by pressing and holding the left mouse button until the thumb is repositioned to the desired location.
