In Depth Information
Because the page header area and Quick Launch bar never change, you may think you are on the
same page and that you have changed only the view of the data.
But look in the address bar as you switch views on a list. You’ll see that you are going to a different
page for each view. It’s just that SharePoint has the header and Quick Launch bar as a common
design theme for all content pages, which can be misleading. What is different between the pages
is the view of the contents. That’s why they’re called content pages .
This becomes particularly important if you are adding web parts to a particular view of a list. When
you change the view, the web parts disappear because they were on the other view’s content page.
As for the categories, you might have noticed that there is a blank category (in which there is
one item). To see what list item might be grouped by that category, click the plus sign next to the
category heading to expand it.
In my example, the Get Started with Microsoft SharePoint Foundation! Announcement was
generated as soon as the site was built before the Category field was added. Because of this, that
list item has no category assigned (see Figure 6.29). This example is a good one if you ever need
to search through a list of items to see whether there is any data missing in a field. Group by
that field (sorting ascending), and the blanks will come out on top. Then you can edit them,
adding the necessary data, until there are no more blanks.
The expanded
empty Category
Another useful feature of this view, as you can see in Figure 6.29, is that a calculation is listed
for each grouping as well. In my example, only the latest expiration dates for each category
appear, but this can be useful for doing total profit or averages; in this case, we can scroll to the
Emergency announcements, expand that group, and see the most recent expiration dates and
the announcements that are still active.
