Displaying a Check Mark for a Row When a Related Record Exists
By pturley, 2010/03/11
Let's say that you have a column
named some_id in an outer-joined table that will return a value if a record exists
and will return null if a record doesn't exist...
Add an image item to a table cell.
Add two embedded images to the
report; a check mark and a blank white square the same size. Let's call the image
files Check.png and Blank.png (or JPG, GIF, BMP, TIF, etc.)
For the Value property of the
image report item, use an expression like:
=IIF(IsNothing(Fields!some_id.Value), "Blank", "Check")
In the table or group footer,
use a COUNT function with the same field: =COUNT(Fields!some_id.Value)
This will only count the existing values.
