Category Expand Button

Category expand buttons enable end-users to expand or collapse category rows (if they have child rows). The paint style of the button depends on the control's paint scheme (e.g., skin).

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

Visibility The VGridOptionsView.ShowButtons property.
Paint style The VGridControlBase.TreeButtonStyle property.
Appearance The VGridAppearanceCollection.CategoryExpandButton property.

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

Custom Draw Event The VGridControlBase.CustomDrawTreeButton event.
