Sets whether to display the page or control.
Page fields and action controls
Group and part controls on pages
True on pages if you want the page or control to be visible; otherwise, false on pages. The default is true on pages.
Visible = false;
Because this property also applies to containers, such as pages and subpages, if the Visible property for the container is set to false, then controls on the container are also not displayed, even if the Visible property is set to true.
On pages, you use the Visible property to show or hide group, part, field, and action controls. You can show or hide the control either statically by setting the property to true or false, or dynamically by using a Boolean variable or a Boolean field on the page. The Boolean field on the page can be either a true/false Boolean or a Boolean expression, such as “Credit Limit > Sales YTD”.
The dynamic options are only possible for group and part controls.
