Error: Some parameters or credentials have not been specified RRS feed

  • Question

  • Hi,

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

    I am using Page_Load event on my report, where I check the postback property, if the postback is false then I set all the parameters except Report Path, 

    The Report Names are available in a drop down. Upon selection of a drop down value and a 'Run Report' button click, I set the Report Path property of the ReportViewer.Server Report

    I get the "Some parameters or credentials have not been supplied" error on the first time I click on the data to drill down. 

    Strangely, if I click on the 'Run Report' button again, the subsequent drill downs work fine.

    In the first case, the ReportViewer's On Error event  is firing, with Exception message as :  Some parameters or credentials have not been specified

    The Report drilldown is working absolutely fine when running via Report Manager.

    Any pointers on how to fix this issue.
