I am not sure if this is doable in SSRS 2005 but I have below mentioned scenario and need your help.
I have three parameters "p1", "p2" and "p3" and three of them have a default null value.
Now.. If I uncheck null from @p1 parameter, I want the p2 and p3 parameter to have the default NULL value checked and if @p1 parameter is set to null meaning if the NULL checkbox for p1 is checked, I want the p2 and p3 parameters to uncheck.
I tried to set the default value via the expression (iif..) and I also create a separate dataset to set the default values but I received an error stating that "forward dependencies are not valid"
I am using VS2005. Please help. Thanks in advance :)
