Could you please post more details. I got the same issue.

My report source is a dataset generated through query(SQL 2005).

I have used ReportDocument's SetDataSource method to assign the data source for the report and I am passing a datatable in to it. The name of the table in the dataset and the table I pass are same.

Here is my code

reportDoc.Load(Server.MapPath(@"Reports\Invoice.rpt"));

reportDoc.SetDataSource(mydatatable);
reportDoc.SetDatabaseLogon(@"domain\uname", "password");

CrystalReportViewer1.ReportSource = reportDoc;
CrystalReportViewer1.DataBind();

I can see the 1st page of the report. but when I try to move to the next page, I get the following error.

Logon failed. Details: crdb_adoplus : Object reference not set to an instance of an object. Error in File C:\Users\LINSEM~1.KEL\AppData\Local\Temp\Invoice {87EFEAE9-9E35-43B9-BB1F-6CF5185D943F}.rpt: Unable to connect: incorrect log on



Could anyone please help.

Hey Linsemon,

I know this waaay too late. But for someone else having the same issue; just do the same thing you do to load data in the first time, in subsequent navigation events. You can tap in to that event by adding a method to "OnNavigate=" attribute of the CrystalReportViewer element, in your aspx page.

Thanks! Yes the object I was binding to was not in sync with what the report was expecting. The error message is a bit misleading and must be been used generically

@deelin

Hi, this error came to me because data set used is not match with the current data schema in the database. may be some columns and data types are different than the original. So i recreate the data set and it worked. Hope this will help you.
