TypeDescription
String A String expression that specifies the parameters to specify options to scroll the control's content while the user moves a node by drag and drop outside of the control's client area. The string indicates the following parameters, separated by comma: the step ( the number of pixels to scroll at once ), 16 pixels, by default ), the number of speeds to scroll ( 5 speeds, by default ), the distance to increase or decrease the speed to scroll the control's content  ( 16 pixels, by default ), the number of mili-seconds to wait until next scroll is performed ( 64 ms, by default ).
By default, the DragOutsideDef property is "16,5,16,64". The DragOutsideDef property has effect while the AllowMoveNode property is not zero ( exDisallow ). Use the DragOutsideDef property to customize the speed to scroll the control's content while the user moves a node by drag and drop outside of the control's chart area. The user can scroll the control's content during drag and drop ( moving a node ), while the cursor hovers outside area of the control. While the cursor is outside of the control and close to the control's margin the speed to scroll is slow. As far as the cursor moves outside far away of control margins the speed is faster.
