最近公司用報(bào)表
有個(gè)需求是做一個(gè)動(dòng)態(tài)的表頭 有點(diǎn)難度了 搜了好久 在阿泰的文章里找到了答案
如果實(shí)現(xiàn)這個(gè)動(dòng)態(tài)列表呢
水晶報(bào)表里有離散值設(shè)置     通過(guò)公式可以來(lái)解決這個(gè)問(wèn)題 通過(guò)參數(shù)來(lái)解決表頭問(wèn)題
  

  //使用報(bào)表對(duì)象加載報(bào)表
            ReportDocument myReport = new ReportDocument();
            string reportPath = Application.StartupPath + "/cp1.rpt";// Server.MapPath("~/app_data/crystalreport1.rpt");
            myReport.Load(reportPath);

            DataDefinition dataDefinition = myReport.DataDefinition;

   string[] Text4formularFields = new string[] { "{Employee.EmployeeID}", "{Employee.EmployeeName}", "{Employee.ProductName}" };
            FormulaFieldDefinitions formularFields = dataDefinition.FormulaFields;
            formularFields[0].Text = Text4formularFields[0];
            formularFields[1].Text = Text4formularFields[1];
            formularFields[2].Text = Text4formularFields[2];
這地方可以搞個(gè)循環(huán)來(lái)解決
以下是加參數(shù) 有點(diǎn)亂

 private ParameterFields GetParameterFields()
        {
            ParameterFields fields = new ParameterFields();

            //單位、部門(mén)、人員、日期范圍參數(shù)
            fields.Add(this.CreateParameterField("title", "單位"));
            fields.Add(this.CreateParameterField("x1", "編號(hào)"));
            fields.Add(this.CreateParameterField("x2", "員工名"));
            fields.Add(this.CreateParameterField("x3", "產(chǎn)品名稱"));
            //fields.Add(this.CreateParameterField("x2", "1"));
            //fields.Add(this.CreateParameterField("x3", "0"));
            //fields.Add(this.CreateParameterField("@empname", "人員"));
            //fields.Add(this.CreateParameterField("@daterange", "日期"));

            //返回
            return fields;
        }
        private ParameterField CreateParameterField(string FieldName, object FieldValue)
        {
            ParameterField field = new ParameterField();
            ParameterDiscreteValue pvalue = new ParameterDiscreteValue();

           
            pvalue.Value = FieldValue;
            field.Name = FieldName;
            field.CurrentValues.Add(pvalue);
            field.AllowCustomValues = false;

            //返回參數(shù)字段
            return field;
        }
