I'm trying to figure out how to display a message box in a ssrs 2008 r2 report. I have custome code that validates a couple of parameters, and I want to display an error message if a user enters an incorrect parameter. I included 'system.windows.forms'
as a reference in my report, and tried to use 'system.windows.forms.messagebox.show(errormsg) but I keep getting an error. I created a hidden parameter that references the custom code.
Any help would be greatly appreciated.
Thanks in advance.
