我在 asp.net(C#) 4.0、SAP Crystal Report 13 中成功创建了 Crystal Report 文档,但问题是单击导出按钮后,它既不导出也不打印,为什么?
代码:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Dataset_load();
}
}
protected void Dataset_load()
{
SqlConnection sqlcon = new SqlConnection(conStr);
SqlCommand sqlCom = new SqlCommand("select * from Login", sqlcon);
SqlDataAdapter sqlDA = new SqlDataAdapter(sqlCom);
// DataSet ds = new DataSet("CRDataSet");
try
{
sqlcon.Open();
//sqlCom.ExecuteNonQuery();
//sqlDA.Fill(ds,"Login");
DataSet1 ds = new DataSet1();
DataTable dt = new DataTable("DT_CR");
sqlDA.Fill(dt);
ds.Tables[0].Merge(dt);
ReportDocument rd = new ReportDocument();
rd.Load(Server.MapPath("CrystalReport.rpt"));
rd.SetDataSource(ds);
CrystalReportViewer1.ReportSource = rd;
}
catch (Exception exc)
{
Response.Write(exc.Message);
}
finally
{
sqlcon.Close();
}
