Interestingly, even though SQL Server Reporting Services is much superior to Active Reports in many respects, it is lacking in a "checkbox" object. This seems to me to be a significant oversight, but it not completely insurmountable.
Although there is no "checkbox" object in Reporting Services, you can emulate one using a TextBox, if you are willing to have an "X" instead of an actual check mark in the box. Just do the following.
Create a new text box, put an "X" in it, and change the following properties to the listed values:
- BorderStyle: Solid
- Color: = IIf (Fields!MyField.Value, "Black", "White")
- Size: .175in, .175in (this fits a 10pt font; make it larger for a bigger font)
