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:


The BaseOptionsView.ShowButtons property.

Paint style

The VGridControlBase.TreeButtonStyle property.


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.
