Type	Default	Description
DefaultBoolean	Default	A DefaultBoolean value that specifies whether smooth pixel-based vertical scrolling is enabled for nodes.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.

Remarks

If the AllowPixelScrolling property is set to Default, the pixel scrolling feature is controlled by the static WindowsFormsSettings.AllowPixelScrolling property.

If the AllowPixelScrolling property is set to True, smooth pixel-based vertical scrolling is enabled for nodes. When pixel scrolling is enabled, you can scroll through nodes in code via the TreeList.TopVisibleNodePixel property.
