后台代码

dsJob dsjob = new dsJob();

SqlConnection scn = new SqlConnection("server=.;uid=sa;pwd=111111;database=pubs;");
scn.Open();

SqlDataAdapter sda = new SqlDataAdapter("select * from jobs", scn);
DataSet ds = new DataSet();
sda.Fill(ds);

if (ds != null && ds.Tables[0].Rows.Count > 0)
{
foreach (DataRow dr in ds.Tables[0].Rows)
{
DataRow drjob = dsjob.Tables[0].NewRow();

drjob["job_id"] = dr["job_id"];
drjob["job_desc"] = dr["job_desc"];

dsjob.Tables[0].Rows.Add(drjob);
}
}

CrystalReportSource crysource = new CrystalReportSource();
crysource.ReportDocument.Load(Server.MapPath("CryPort.rpt"));

//给水晶报表上的文本控件赋值

TextObject textobj = (TextObject)crysource.ReportDocument.ReportDefinition.ReportObjects["Text3"];
textobj.Text = "chen ping";

crysource.ReportDocument.SetDataSource(dsjob);
crysource.DataBind();

cryview.ReportSource = crysource;
cryview.DataBind();

//给报表上的 text 控件赋值

TextObject txtname = (TextObject)crysource.ReportDocument.ReportDefinition.ReportObjects["控件Name"];
txtname.Text = "";
