Hi guys, I am currently generating a rdlc report in Visual Studio 2010 and embedding it into an asp page using a reportviewer control. My dataset is based on entity framework. The report runs fine and returns plenty of data in the format I want. Whenever I add a parameter to the report the reportviewer control on my page is just blank. I'm setting the parameter "available values" from a field in the same dataset used to generate the report but even if I add an empty parameter with no available values the reportviewer control is still blank. Any ideas where I'm going wrong? Thanks in advance. EDIT: I forgot to add this is the same in both Internet Explorer 8 and Firefox 5.

SOLVED I had forgotten to add a default value for the parameter I was adding. The report works as desired now.
