Error: Some parameters or credentials have not been specified


  • Hi,

    I am using report viewer control on my web page.  I have drill down report that I open using report viewer control with ProcessingMode="Remote".

    Sometimes I get "Some parameters or credentials have not been specified" error, while I toggle the drill down report. I am only using Page_Load event on my report, where I just check the postback property, if the postback is false then I set all the parameters otherwise, do nothing, the report viewer automatically syncs with report server to get the data for drill down report.

    Once I get the above error, I tried to REFRESH the report, but still get the same error.

    I am not even able to catch this exception in my page load event, it seems the report viewer control understands and consumes this exception and returns the above said error message.

    Please help me out.

    Thanks in advance,
