Need to remove Empty pages when subreport is returning no data (IReport)

I have a subreport inside a main report on a new page due to the layout. When the subreport generates no data(sql table is empty), there is a blank page generated in the mainpage. How can i omit this empty page? please开发者_开发技巧 help me here..

You can try to work around by using the <printWhenExpression> construct or try it with isRemoveLineWhenBlank
