Sets or gets the total number of pages shown in a pagination bar.
Setting the totalPages property updates the number of pages shown in
the pagination bar.
Setting totalPages to a value less than currentPage
causes currentPage to be reset to the new totalPages value. For
example, if currentPage is 8 and totalPages is set to 5, currentPage
is reset automatically to 5.
If the pagination bar is connected to a dataset, it is recommended that
you allow the dateset to control the pagination bar's totalPages value.
Getting the totalPages property returns the total number of pages available
for selection in the pagination bar. If the pagination bar is
connected to a dataset, the initial totalPages value is calculated based
on the total number of items in the dataset and the dataset's page size.
