ContainerProperties.HeadingStyle Property (Visio)
Determines the appearance and position of the heading of the container. Read/write.
expression An expression that returns a ContainerProperties object.
The value of the HeadingStyle property corresponds to the numerical identifier of the heading style that is selected in the Heading Styles gallery in the Container Styles group on the Container Tools Format tab.
The value of the HeadingStyle should always be greater than or equal to zero (0). A value of zero means that the container does not display a heading.
If no value is assigned to the HeadingStyle property or it is set to a null value, a runtime error ensues. A runtime error also ensues if you assign the property a value less than 0 or greater than the maximum ID number in the Heading Styles gallery.
