Empty Area
Empty areas appear when cells do not occupy the entire control’s area. This can occur when there are only a few nodes, total column widths are less than the Tree List’s width or as a result of vertical scrolling.
The table below lists the main properties that affect the element’s appearance:
Appearance | The TreeListAppearanceCollection.Empty property. |
Custom Draw Event | The TreeList.CustomDrawEmptyArea event. |
