使用参数将文本框的值传递给水晶报表

问题描述

我尝试将文本框值传递给asp.net中的水晶报表。

但它不会在我的代码中输入fount参数。它将显示弹出参数对话框窗口以获取水晶报告的值。

以下是我参数传递的源代码：

I am Try to pass text box values to crystal report in asp.net.
but it will not fount parameter in my code. it will show popup parameter dialog box window to get value for crystal report.
Below is my Source code for parameter Passing :

ReportDocument reportDocument = new ReportDocument();
ParameterFields paramFields = new ParameterFields();

ParameterField paramField = new ParameterField();
ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
paramField.Name = "@Name";
paramDiscreteValue.Value = TextBox1.Text.ToString();
paramField.CurrentValues.Add(paramDiscreteValue);
paramFields.Add(paramField);
CrystalReportViewer1.ParameterFieldInfo = paramFields;
reportDocument.Load(Server.MapPath("CrystalReport1.rpt"));

if (conn.State == ConnectionState.Open)
{
   conn.Close();
}

conn.Open();
string sql = "select * from CustomerDetails";
OdbcCommand cmd = new OdbcCommand(sql, conn);
OdbcDataAdapter dscmd = new OdbcDataAdapter(cmd);
DataTable datatable = new DataTable();
dscmd.Fill(datatable);
conn.Close();
reportDocument.SetDataSource(datatable);
CrystalReportViewer1.ReportSource = reportDocument;

推荐答案

reportDocument.SetDataSource(datatable);
reportDocument.SetParameterValue("Name", TextBox1.Text);
CrystalReportViewer1.ReportSource = reportDocument;
