Well.. For using crystal report we need to have typed dataset on the page. First create a new connexion (say con) , dataadapter(say daEx) and typed dataset ( say dsEx1).

Then Design a Crystal Report and add it to your project. This can be done using the Add New Item in the Project Menu. In the resulting dialog select the CrystalReport Option ( The Crystal Report comes with Visual Studio .Net U dont need to install anything). A wizard will be poped up to ghuide you thru the process of creating the report. Say teh Name of the Crystal Report is CrystalReport1.rpt.

Then place a CrystalReportViewer Control ( found in the toolbox --> WebControls Tab say CrystalReportViewer1) on to your form. Donot make any changes to the properties of the CrystalReportViewer Control.

Then place a reportDocument Control (found in the Components tab of the toolbox say reportDocument 1) on the form.

Whenever u want to show the report letus say in button1 click event write

reportDocument1.Load(MapPath("CrystalReport1.rpt"))
reportDocument1.SetDataSource(dsEx1)
CrystalReportViewer1.ReportSource = reportDocument1

That it u r done with showing crystal report.



Note: If you r using .Net 2002 U might get a NullReference Exception. The only thiing I know to get rid of this exception is to upgrade to .Net 2003
