SftBox/OCX 5.0 - Combo Box Control

Scrolling

Horizontal Scroll Bar

SftBox/OCX fully supports horizontal scrolling. With SftBox/OCX, adding a horizontal scroll bar is very easy, even if multiple columns are used. The Scrollbars property must be suitably defined. After all items have been added and all attributes have been defined, Items.RecalcHorizontalExtent must be used so SftBox/OCX can evaluate the optimal horizontal scrolling extent and add a horizontal scroll bar to the drop down portion of the control.

If Items.RecalcHorizontalExtent (or the Items.HorizontalExtent property) is not used, horizontal scrolling is not available.

Vertical Scroll Bar

The Scrollbars property must be suitably defined to enable vertical scrolling.
