Hi debashish,
Drag and drop crystal report viewer to ur designer page and in the page load event set the following information:
CrystalReportViewer1.ReportSource = "Path Of the Report"
CrystalReportViewer1.LogOnInfo.Item
(0).ConnectionInfo.ServerName = "ServerName"
CrystalReportViewer1.LogOnInfo.Item
(0).ConnectionInfo.DataBaseName= "DataBaseName"
CrystalReportViewer1.LogOnInfo.Item
(0).ConnectionInfo.UerID = "UserID"
CrystalReportViewer1.LogOnInfo.Item
(0).ConnectionInfo.password = "password"
CrystalReportViewer1.DataBind()
U can view the report now.
