Always Expand groups on export/print of an rdlc report SSRS(even if user has explicitly collapsed the group)

Hi,

I am facing a problem in creation of an rdlc ssrs report.

Scenario  is as follows:

• The report has Expand all/Collapse all radiobutton option to toggle a group's visibility.
• Report should always be in expanded state if exported to pdf,word etc or printed(even if currently it is collapsed by the user).

This is implemented in rdl report by using a global inbuilt variable “RenderFormat”(below is the condition used over the grouped region which is to be expanded in case of exports/print from the toolbar )

----------  to show expanded data when report is rendered/or printed--------------

=iif(Parameters!ExpandAll.Value = 0,iif(Globals!RenderFormat.Name = "WORD" or Globals!RenderFormat.Name = "EXCEL" or

Globals!RenderFormat.Name = "PDF" or Globals!RenderFormat.Name = "MHTML" or Globals!RenderFormat.Name = "IMAGE",false,true),False)

-----------------------------------------------------------------------------------------------

However the said variable is unavailable to use in local reports.

How can I implement it for RDLC of the same report?
