Error: 'RSClientController' is undefined
Error: 'document.getElementByID(...).ClientController' is null or not an object
Report viewer form is then empty. I have searched all the web, found some potential answers, tried all of them, to no avail. This is a critical error and my client is not pleased with the amount of time it is taking to resolve this issue. Microsoft has been no help, and I am stuck after trying all found suggestions.
Report works fine in Business Intelligence Development Studio, as well as from the Report Server itself, just not in the .NET code on the web server.
If you respond, I can tick-off all the potential solutions I have already tried. Thank you. This is a crtitical issue.
