Can the left part of the chart support horizontal scroll bar?
Yes. The ColumnAutoResize property specifies whether the left part of the control displays a horizontal scroll bar if required, or resizes the visible columns so all of them are displayed on the left part of the control. So, the horizontal scroll bar in the left part of the control is not shown while the ColumnAutoResize property is True. So, in order to display a scrollbar in the left side of the control, you need to set the ColumnAutoResize property on False. If the scroll bar is not shown, you can use the ScrollBars property on exDisableBoth and so the scroll bar is always visible. In conclusion, the horizontal scroll bar in the left part of the control is shown only if: • ColumnAutoResize property is False • ScrollBars property contains exDisableBoth or exDisableNoHorizontal, or if not, the scroll bar is shown only if requires. For instance if the width of the visible columns is less than the control’s client area the scroll bar is not shown, else it is shown.
