Enable DragRange


The EnableDragRange property of RadSlider specifies the behavior of the slider, when the user clicks on its selected region element. The value of this property influences the behavior of the control only in case IsSelectionRangeEnabled property is set to true.

The possible values for EnableDragRange are:
  • false (default value) - When the user clicks on the selected region element, the dragHandle (thumb) that is closest to the point where he/she clicked, will move either with the value of LargeChange, or to the nearest to that point value, in case LargeChange is 0.
  • true - When the user clicks on the selected region element and holds the left mouse button down, he/she can drag the selected region element, thus changing both SelectionStart and SelectionEnd values.
