Examples

The following code illustrates how to get the pivot table data field by data field name.

      using (ExcelEngine excelEngine = new ExcelEngine())
      {
        //Create a worksheet.        
        IApplication application = excelEngine.Excel;
        application.DefaultVersion = ExcelVersion.Excel2013;
        IWorkbook workbook = application.Workbooks.Create(2);
        IWorksheet sheet = workbook.Worksheets[0];
        IWorksheet pivotSheet = workbook.Worksheets[1];
        sheet.Range["A1"].Text = "Student ID";
        sheet.Range["B1"].Text = "Student Name";
        sheet.Range["C1"].Text = "Mark(Out of 100)";
        sheet.Range["D1"].Text = "Student City";

        pivotTable.Fields[1].Axis = PivotAxisTypes.Row;
        pivotTable.Fields[3].Axis = PivotAxisTypes.Column;
        IPivotField datafield = pivotTable.Fields[2];
        pivotTable.DataFields.Add(datafield, "Sum of Marks", PivotSubtotalTypes.Sum);

        //Gets a pivot data field with the specified name from the collection
        IPivotDataField pivotDataField = pivotTable.DataFields["Sum of Marks"];
        pivotDataField.Name = "SUM Marks";
        pivotDataField.Subtotal = PivotSubtotalTypes.Average;

        pivotTable.BuiltInStyle = PivotBuiltInStyles.PivotStyleMedium20;
        workbook.SaveAs("PivotTables.xlsx");
        workbook.Close();
      }

Examples

Following code snippet illustrates how to add a pivot data field to the pivot table.

ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
IWorkbook workbook = application.Workbooks.Open("Sample.xlsx");
IWorksheet worksheet = workbook.Worksheets[0];

// Create Pivot cache with the given data range
IPivotCache cache = workbook.PivotCaches.Add(worksheet["A1:H50"]);  
//Create "PivotTable1" with the cache at the specified range
IPivotTable pivotTable = worksheet.PivotTables.Add("PivotTable1", worksheet["A1"], cache);
//Add Pivot table fields (Row and Column fields)
pivotTable.Fields[2].Axis = PivotAxisTypes.Row;
pivotTable.Fields[6].Axis = PivotAxisTypes.Row;
pivotTable.Fields[3].Axis = PivotAxisTypes.Column;

//Add data field
IPivotField field = pivotTable.Fields[5];
pivotTable.DataFields.Add(field, "Sum", PivotSubtotalTypes.Sum);
