Need to add Crystal Reports Viewer to Tool Bar
How do I add Crystal Reports Viewer to the Toolbar in Visual Studio 2005?
If both the suggestions would help you than it might be possible that Crystal Report is not get integrated with Visual studio.
If you are using any seperate product of Crystal report than first install VS and than CR.
and if you are using the CR which comes with VS2005 than you need to reinstall it again.
Hope this helps.
