Expand Button

Expand buttons enable end-users to expand or collapse parent rows (rows that have child rows). The paint style of buttons is dependent on the control's paint scheme (e.g., skin).

The table below lists the main properties that affect element appearance:

Visibility

The BaseOptionsView.ShowButtons property.

Paint style

The paint style is automatically chosen depending on the control's paint scheme.

Appearance

The VGridAppearanceCollection.ExpandButton property.

Note: the appearance settings that specify the background and border colors are ignored if a vertical grid is painted in the WindowsXP, Office2003 or Skin style.

Custom Draw Event

The VGridControlBase.CustomDrawTreeButton event.
