crystal report viewer Toolbar
I am developing reports on Crystal Reports XI R2, VS.NET 2005 , SQL Server 2000, C#.
When i run the report it generates the report fine but after a minute when I click on the toolbar either for print or export or drilldown or search or zoom or group tree or others i get a error
Database Logon Failed
Error in Crystal report viewer14
Object reference not set to an instance of an object
Any kind of help it is appreciated.
