TBaseReport. PIVar property

 Top  Previous  Next
Declaration
function PIVar(PIVarName: String): String;

 

Category

 

Description
This method allows you to initialize the value of a PIVar (Post Initialize Variable). Any PIVars of the same name that were previously printed will show this value. PIVars will use the value that is set after it is printed. A common use for PIVars is to print a total in a header band that would be initialized later in the footer band. This works even across multiple pages. TRvSystem.SystemOptions.soUseFiler must be true if you are using PIVars in your report.
