EditMask, MultiLineEdit controls
When automatic vertical scrolling is enabled, text in the control scrolls up or down automatically when the user enters or modifies data. When automatic vertical scrolling is not enabled, text does not scroll up or down automatically as the user changes data, and data that exceeds the height of the space provided is ignored.
To enable automatic vertical scrolling:
Select the AutoVScroll check box on the General page of the object’s Properties view.
The AutoVScroll property takes a boolean value. The following example enables automatic vertical scrolling:
mle_1.AutoVscroll = TRUE
This property cannot be set at runtime for EditMask controls.
