Question 9: How to open the drill- through report in a new browser window?
Answer:
Generally, if you use the "Jump to URL" option for a textbox, it will redirect to the specific URL in the same browser whn the user clicks on the textbox.
To open the link in a new window, you can use syntax similar to this:
="javascript:void window.open ('http://servername/reportserver?/freportfolder/ReportName&Parameter1="& Fields!Field1.Value & "&Field2="& Fields!Field2.Value & "&rs:Command=Render','_blank','resizeable=1,toolbar=0,status=0,menu=0,top=20,left=20,width=740,height=730')"
