Crystal Report数据源和报告参数每件事情都顺利但是当我转到报告查看器页面时，它只显示空白页面。



这是代码

Hi!
I am New to Crystal Reports, and I have some issue. I am working with ASP.NET 4.5 Using VS2012. I have created the Crystal Report but that is not showing in the Crystal Report Viewer, It shows the blank page.
Crystal Report Data Source and Report Parameter every thing goes well but when i go to the report viewer page it shows nothing only the blank page.

Here is the Code

ReportDocument rpt = new ReportDocument();

rpt.Load(Server.MapPath("ReportEngine.rpt"));

CrystalReportViewer1.ReportSource = rpt;

rpt.SetDatabaseLogon("sa", "123");

ReportDataSet DS = new ReportDataSet();

using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["DbConnectionString"]))
{
con.Open();
string query = "SELECT ID As Column1,NameEn As Column2, NameAr As Column3, Email As Column4, Email As Column5";

SqlCommand cmd = new SqlCommand(query, con);
SqlDataAdapter adapter = new SqlDataAdapter(query, con);
adapter.Fill(DS, "ReportTable");
rpt.SetDataSource(DS);
}
string[] cols = { "ID", "NameEn", "NameAr", "Email", "Email" };

for (int i = 0; i < cols.Length; i++)
{
rpt.SetParameterValue(i, cols[i].ToString());
}
CrystalReportViewer1.ReportSource = rpt;

先谢谢

Thanks in Advance
