将价值传递给水晶报告

Question

我很难弄清楚如何查看或查看从Visual Studio 2010 C＃到Crystal Report的值。这是我希望在Crystal Report中查看我的报告的方法。

As of ????(4:30PM): ????(December), ????(2011)
Juan Dela Cruz
Count:    10
Score:    5
Grade:    ????(50.00)

下面的代码是我的SEARCH按钮，用于查找该特定员工的摘要。

            try
            {
                econ = new SqlConnection();
                econ.ConnectionString = emp_con;
                econ.Open();
                float iGrade = 0;
                float Grade = 0.00F;
                string Log_User;
                float Count, Score;
                string date = DateTime.Now.ToShortTimeString();
                ecmd = new SqlCommand("SELECT Log_User, Count = COUNT(Det_Score), Score = SUM(Det_Score) FROM MEMBER M,DETAILS D WHERE D.Emp_Id = M.Emp_Id AND Log_User like" + "'" + Convert.ToString(comEmployee.Text) + "'AND Month(Sched_Start) =" + "'" + Convert.ToInt32(iMonth) + "'AND Year(Sched_Start) =" + "'" + Convert.ToInt32(txtYear.Text) + "'GROUP BY Log_User", econ);
                ecmd.CommandType = CommandType.Text;
                ecmd.Connection = econ;
                dr = ecmd.ExecuteReader();
                while (dr.Read())
                {
                    if (dr == null || !dr.HasRows)
                    {
                        MessageBox.Show("No record found.", "Error");
                    }
                    else
                    {
                        Log_User = (string)dr["Log_User"];
                        Count = (dr["Count"] as int?) ?? 0;
                        Score = (dr["Score"] as int?) ?? 0;
                        try
                        {
                            iGrade = Score / Count;
                            Grade = iGrade * 100;
                        }
                        catch (DivideByZeroException)
                        {
                            Console.WriteLine("Exception occured");
                        }
                    }
                }
                econ.Close();

下面的代码是我的Crystal Report，用于从数据库中获取值：其中包括：Log_User，Month和Year。

                ParameterFields myParams = new ParameterFields();

                ParameterField name = new ParameterField();
                ParameterDiscreteValue valName = new ParameterDiscreteValue();
                name.ParameterFieldName = "@Log_User";
                valName.Value = comEmployee.Text;
                name.CurrentValues.Add(valName);
                myParams.Add(name);

                ParameterField month = new ParameterField();
                ParameterDiscreteValue valMonth = new ParameterDiscreteValue();
                month.ParameterFieldName = "@Month";
                valMonth.Value = Convert.ToInt32(iMonth);
                month.CurrentValues.Add(valMonth);
                myParams.Add(month);

                ParameterField year = new ParameterField();
                ParameterDiscreteValue valYear = new ParameterDiscreteValue();
                year.ParameterFieldName = "@Year";
                valYear.Value = Convert.ToInt32(txtYear.Text);
                year.CurrentValues.Add(valYear);
                myParams.Add(year);

                crystalReportViewer1.ParameterFieldInfo = myParams;

                crystalReportViewer1.ReportSource = CrystalReport81;

            }
            catch (Exception x)
            {
                MessageBox.Show(x.GetBaseException().ToString(), "Connection Status", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }

我只想在报告中查看我的输入参数以及成绩。.（所有具有????的值）我知道那里有人可以帮助我找出答案。 之后，我就完成了我的项目。

Answer 1

 TextObject yr = (TextObject)CrystalReport81.ReportDefinition.Sections["Section3"].ReportObjects["Text1"];
                yr.Text = txtYear.Text;

表单文本框->水晶报告文本框

通过添加上面的代码，您可以显示在文本框中输入的值。.但是首先，您在Crystal Report中应该有一个空的文本框，因为这将捕获从FORM文本框中抛出的值

我希望它可以帮助其他人。因为它对我有很大帮助。
