Rave Reports Visual Designer

Example Parameters .

Sample event that GET's a parameter named "LineCount", "increments" it, and then SET's (saves) it. This could be used if you wanted to have row counts with a Master-Detail-Detail relationship with 2 or more details groups.

Remember that parameters must be a string value.

{ Event for DataTextCount1.OnGetText }

function DataTextCount1_OnGetText(Self: TRaveDataText; var Value: string);

var

  iCount: Integer;

  sCount: String;

begin

  iCount := StrToInt(RaveProject.GetParam('LineCount'));

  sCount := IntToStr(iCount + 1);

  Value := sCount;

  RaveProject.SetParam('LineCount', sCount);

end OnGetText;
