I have template excel which resides on the server directory and i am using this code to bind all data from dataset/data dreader to my template excel
http://steveorr.net/articles/ExcelExport.aspx.
Excel has 2 sheets 1 for data and other for pivot tables - so everytime data loads and I have done that refresh property clicked ......blah blah.....so i get new pivot tables everytime.
1> If i use Aspose Excel instead of MS Excel - what benefits will I get.
2>I sent you asp.net code - if I use Aspose excel then how will I open the template excel ?
Using the latest Aspose.Cells APIs, it is quite easy to create Pivot tables and pivot charts in Excel spreadsheets. See the sample code for your reference:
e.g Sample code:
// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Obtaining the reference of the newly added worksheet
Worksheet sheet = workbook.Worksheets[0];
Cells cells = sheet.Cells;
// Setting the value to the cells
Cell cell = cells["A1"];
cell.PutValue("Sport");
cell = cells["B1"];
cell.PutValue("Quarter");
cell = cells["C1"];
cell.PutValue("Sales");
cell = cells["A2"];
cell.PutValue("Golf");
cell = cells["A3"];
cell.PutValue("Golf");
cell = cells["A4"];
cell.PutValue("Tennis");
cell = cells["A5"];
cell.PutValue("Tennis");
cell = cells["A6"];
cell.PutValue("Tennis");
cell = cells["A7"];
cell.PutValue("Tennis");
cell = cells["A8"];
cell.PutValue("Golf");
cell = cells["B2"];
cell.PutValue("Qtr3");
cell = cells["B3"];
cell.PutValue("Qtr4");
cell = cells["B4"];
cell.PutValue("Qtr3");
cell = cells["B5"];
cell.PutValue("Qtr4");
cell = cells["B6"];
cell.PutValue("Qtr3");
cell = cells["B7"];
cell.PutValue("Qtr4");
cell = cells["B8"];
cell.PutValue("Qtr3");
cell = cells["C2"];
cell.PutValue(1500);
cell = cells["C3"];
cell.PutValue(2000);
cell = cells["C4"];
cell.PutValue(600);
cell = cells["C5"];
cell.PutValue(1500);
cell = cells["C6"];
cell.PutValue(4070);
cell = cells["C7"];
cell.PutValue(5000);
cell = cells["C8"];
cell.PutValue(6430);
Aspose.Cells.Pivot.PivotTableCollection pivotTables = sheet.PivotTables;
// Adding a PivotTable to the worksheet
int index = pivotTables.Add("=A1:C8", "E3", "PivotTable2");
// Accessing the instance of the newly added PivotTable
Aspose.Cells.Pivot.PivotTable pivotTable = pivotTables[index];
// Unshowing grand totals for rows.
pivotTable.RowGrand = false;
// Draging the first field to the row area.
pivotTable.AddFieldToArea(Aspose.Cells.Pivot.PivotFieldType.Row, 0);
// Draging the second field to the column area.
pivotTable.AddFieldToArea(Aspose.Cells.Pivot.PivotFieldType.Column, 1);
// Draging the third field to the data area.
pivotTable.AddFieldToArea(Aspose.Cells.Pivot.PivotFieldType.Data, 2);
// Saving the Excel file
workbook.Save(dataDir + "pivotTable_test_out.xls");
