Property Value

Type	Default	Description
DefaultBoolean	Default	A DefaultBoolean enumeration value that specifies whether it is allowed to scroll pictures using the mouse wheel.

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.
Default	The default behavior determined by the control’s logic.

Remarks

Scrolling using the mouse wheel can be performed in the following cases:

• the AllowScrollOnMouseWheel property is set to Default and the RepositoryItemPictureEdit.ShowScrollBars is set to true;
• the AllowScrollOnMouseWheel property is set to True.

The mouse wheel can also be used to zoom pictures (see RepositoryItemPictureEdit.AllowZoomOnMouseWheel). By default, zooming is performed if the CTRL modifier key is pressed (see RepositoryItemPictureEdit.ZoomingOperationMode), scrolling is performed if no modifier key is pressed. If no modifier key is required to zoom pictures, scrolling using the mouse wheel cannot be performed.
