Report viewer does not load, showing blank space - running local RDLC files

Question

I got a problem with reporting services, running local rdlc files on the 2005 version.

I have in the HTML a report viewer set to run locally as follows :

Answer 1

In my case, ReportViewer control does not provide error messages (EventViewer nor ReportViewer control body), just blank page. I think this make hard find and fix the issue. Yoel Halb's answer was my key!

A property called IsReadyForRendering was False. In the BOL refers to parameters topic.

I could inspect every value of the whole parameters with the code (you can execute it from immediate window)

   var parameters = ReportViewer1.LocalReport.GetParameters()

You will find the problematic parameter when you look the property State with the value "MissingValidValue"

Hope this helps !
