I need to get SSRS report through a Form POST Method. Everything work as expected (when defining input names and values) with one exception - I can't figure out how to set null as value. I tried set "Null", "IsNull=True", ":IsNull=True", "-1" and "".
Everything cause Report to show only error msg:
"The value provided for the report parameter 'ParamName' is not valid for its type. (rsReportParameterTypeMismatch)"
When I get report through URL GET method, i put ":IsNull=True" there in case of null is desired. So it looks like example.com/ReportServer/Pages/ReportViewer.aspx?%2fOB%20test/report7&rs:Command=Render&ParamName:IsNull=True
What should I set for value in input for report through a POST Method?
Thanks!
Note: Reason for usage of POST Method for me is URL length limit...
