Rave Reports Visual Designer

CalcText component (TRaveCalcText) - Report Tab

The "CalcText" component is data aware. It is very similar to the dbEdit component in Delphi. This means you can use it to display a field from a dataset just about anywhere on the page layout. The main difference between "DataText" and "CalcText" is that "CalcText" is specially designed to do some form of calculation and placing the results of that calculation somewhere on the page layout.

The CalcType property determines the type of calculation being performed and includes Average, Count, Maximum, Minimum, and Sum. For example, this could be used to print the Totals of an invoice at the top of each page of an invoice.

If your field might contain blanks, then be sure to set the CountBlanks property to get the behavior you desire. The CountBlanks property determines whether blank field values are included in the Average and Count calculation methods.

If RunningTotal is true then the calculation will not be reset to 0 each time it is printed.
