The object model for the C1Report component is largely based on the Microsoft Access model, except that Access has different types of controls (label control, textbox control, line control, and so on), while C1Report has a single Field object with properties that can make it look like a label, textbox, line, picture, subreport, and so on.
The following table lists all objects, along with their main properties and methods (note that C1Report uses twips for all measurements. One twip is 1/20 point, so 72 points = 1440 twips = 1 inch):
