WinForm中的水晶报表:
1:在窗体上加一个crystalReportViewer;
2:添加一个新的CrystalReport并且设计(可以先加一个数据集,然后在向导中添加到报表中)
3:在Form的Load()事件中:
            DataTable dt = new DataTable();           
            sring source = "server=(local);integrated security=sspi;database=northwind";
            string select = "select * from products";
            SqlConnection conn = new SqlConnection(source);           
            conn.Open();
            SqlCommand cmd = new SqlCommand(select, conn);
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            sda.Fill(dt);
            //********************
            CrystalReport1 gxyCR = new CrystalReport1();
            gxyCR.SetDataSource(dt);
            crystalReportViewer1.ReportSource = gxyCR
4:运行OK!
Web中的水晶报表:
在Web上就不能用上面的方法了!!!!
1:在窗上加入CrystalReportViewer控件,并加上CrystalReportSource控件
2:添加一个新的CrystalReport并且设计(可以先加一个数据集,然后在向导中添加到报表中)
3:在Page_load()中添加代码如下:
        DataTable dt = new DataTable();
        string conn = "server=(local);integrated security=sspi;database=northwind";
        SqlConnection SqlConn = new SqlConnection(conn);
        SqlConn.Open();
        SqlCommand cmd = new SqlCommand("select * from products", SqlConn);
        SqlDataAdapter SDA = new SqlDataAdapter(cmd);
        SDA.Fill(dt);

        CrystalReportSource1.ReportDocument.Load(Server.MapPath("CrystalReport.rpt"));
        CrystalReportSource1.ReportDocument.SetDataSource(dt);
        CrystalReportViewer1.ReportSource=CrystalReportSource1.ReportDocument;
        CrystalReportSource1.DataBind();
       //动态改变标题
       TextObject to = (TextObject)CrystalReportSource1.ReportDocument.ReportDefinition.ReportObjects["title1"];
        to.Text = "gggggggggg";
4:运行页面OK!
