Remarks

Handle the LeftCoordChanged event to perform specific actions each time the control’s content is scrolled horizontally. Horizontal scrolling can be performed by end-users. To scroll the control in code, use the TreeList.LeftCoord property. You can use this property while handling the LeftCoordChanged event to determine the current scrolling offset.

Horizontal scrolling can be performed when the total width of columns exceeds the control’s client area. This can only be possible if the TreeListOptionsView.AutoWidth option is disabled.

Handle the TreeList.TopVisibleNodeIndexChanged event to perform specific actions each time vertical scrolling is performed.
