Working with Items in a Report
A report in Reporting Services uses report items to display data and
graphical elements. In addition to the data regions table, matrix,
list, and chart, report items also include text box, image, line,
rectangle, and subreport.
Text Box
Text boxes display all text data in a report. A table or matrix cell
include a text boxes by default to display data. Text boxes can be
placed anywhere on a report and can contain labels, fields, or
calculated data. You use expressions to define data in text boxes.
Image
Images display binary image data in a report. An image report item
can use a URL to display an image stored on a Web server, display
embedded image data, or display an image from binary data in a
database. Reporting Services supports .bmp, .jpeg, .gif, and .png
files.
Line
Lines are graphical elements that you can place anywhere on a page.
A line is defined with a start and end point and can have a number of
styles (for example, weight and color) assigned to it. A line has no
data associated with it.
Rectangle
Rectangles can be used in two ways: as a graphical element and as a
container for other report items. When you place report items within a
rectangle, you can move them with the rectangle. This is useful for
keeping numerous text boxes and other items together in a report.
Subreport
A subreport is an item in a report that points to another report on
the report server. The report that the subreport refers to can be a
full report that can also run on its own, or it can be a report that
looks best when embedded within the main report. When you define a
subreport, you can also define parameters to filter data in the
subreport.
When deciding whether to use a subreport, you may want to consider
using a data region instead. Because the report server processes each
instance of a subreport as a separate report, performance can be an
issue. Data regions provide much of the same functionality and
flexibility as subreports, but with better performance.
Item Properties
All items in a report, including groups, table and matrix columns
and rows, the above items, and the report itself, have properties
associated with it. These properties govern the appearance and behavior
of the item. For information about the properties associated with an
item, see the documentation for that item.
