I have to pass 4 parameters to ssrs report, this is how my url looks
Response.Redirect("http://ups117850/rpt/Pages/Rept.aspx?ItemPath=%2feMaaS%2feMaaS&rs:Command=render&studentId=" + studentID + "&startdate=" + StartDate + "&enddate=" + EndDate + "&type=" + type);
studentid=1031
startdate=4/1/2011
enddate=4/30/2011
type=student
ssrs throws error 'parameters validation failed"
