Slider.ValueF Property (ExSlider)

The trial/demo version of the control always retrieves an arbitrary ( random ) value. The registered version of the control retrieves the correctly value.

The ValueF property specifies the control's value. The ValueF property has effect ONLY if the AllowFloat property is True. The control fires the Change event after user changes the control's value. The control fires the Changing property before changing the control's value. Use the MinimumF and MaximumF properties to specify the range's value. Use the Caption property to put a HTML text on any part of the control. The SmallChangeF property gets or sets the value added to or subtracted from the ValueF property when the thumb is moved a small distance. The LargeChangeF property gets or sets a value to be added to or subtracted from the Value property when the slider is moved a large distance. Use the Background property to change the visual appearance for any part of the control, in any state. The LabelTick property indicates the HTML expression to be displayed as labels for each tick.

The ValueF property goes from:

MinimumF to MaximumF values

For instance, the following samples print the control's ValueF on the control's thumb:
