Property (As Integer )
aScrollbar.LineStep = newIntegerValue
IntegerValue = aScrollbar.LineStep

Supported for all project types and targets.

The amount the value changes when a scroll arrow is clicked. The default is 1.


MacOS does not show scrollbar arrows so there is no way to cause a "LineStep".

Sample Code

This example is in the Open event of the Scrollbar. It sets the Minimum, Maximum, and LineStep properties.

Me.Minimum = 0
Me.Maximum = 200
Me.LineStep = 10
