When exported to PDF, margins set in "Report Layout" are being ingored by ASPOSE.
In the attached rdl file, I have the set the top margin as 0.5in Both of these values were ignored by the ASPOSE.
In order to set the margin, I opened report properties window Report -> Report Properties. Then I clicked on "Layout tab" and specified the margins there.
I am attaching the rdl file and the generated PDF. Also attaching a image with description of the problem.
