Auto Filter Data in VSTO and Aspose.Cells

To apply auto-filtering to a column:
- Create a workbook.
- Get a worksheet.
- Add sample data.
- Apply auto-filter.
- Auto-fit columns to make the display attractive.
- Save the spreadsheet.
The code samples in this article show how to perform these steps using VSTO with either C#, or using Apose.Cells, again with either C#.
VSTO
Excel.Application ExcelApp = Application;
//Add a Workbook.
Excel.Workbook objBook = ExcelApp.Workbooks.Add(System.Reflection.Missing.Value);
//Get the First sheet.
Excel.Worksheet sheet = (Excel.Worksheet)objBook.Sheets["Sheet1"];
//Add data into A1 and B1 Cells as headers.
sheet.Cells[1, 1] = "Product ID";
sheet.Cells[1, 2] = "Product Name";
//Add data into details cells.
sheet.Cells[2, 1] = 1;
sheet.Cells[3, 1] = 2;
sheet.Cells[4, 1] = 3;
sheet.Cells[5, 1] = 4;
sheet.Cells[2, 2] = "Apples";
sheet.Cells[3, 2] = "Bananas";
sheet.Cells[4, 2] = "Grapes";
sheet.Cells[5, 2] = "Oranges";
//Enable Auto-filter.
sheet.EnableAutoFilter = true;
//Create the range.
Excel.Range range = sheet.get_Range("A1", "B5");
//Auto-filter the range.
range.AutoFilter("1", "<>", Microsoft.Office.Interop.Excel.XlAutoFilterOperator.xlOr, "", true);
//Auto-fit the second column.
sheet.get_Range("B1", "B5").EntireColumn.AutoFit();
//Save the copy of workbook as .xlsx file.
objBook.SaveCopyAs("vsto_autofilter.xlsx");
Aspose.Cells
//Instantiate a new Workbook.
Workbook objBook = new Workbook();
//Get the First sheet.
Worksheet sheet = objBook.Worksheets["Sheet1"];
//Add data into A1 and B1 Cells as headers.
sheet.Cells[0, 0].PutValue("Product ID");
sheet.Cells[0, 1].PutValue("Product Name");
//Add data into details cells.
sheet.Cells[1, 0].PutValue(1);
sheet.Cells[2, 0].PutValue(2);
sheet.Cells[3, 0].PutValue(3);
sheet.Cells[4, 0].PutValue(4);
sheet.Cells[1, 1].PutValue("Apples");
sheet.Cells[2, 1].PutValue("Bananas");
sheet.Cells[3, 1].PutValue("Grapes");
sheet.Cells[4, 1].PutValue("Oranges");
//Auto-filter the range.
sheet.AutoFilter.Range = "A1:B5";
//Auto-fit the second column.
sheet.AutoFitColumn(1, 0, 4);
//Save the copy of workbook as .xlsx file.
objBook.Save("aspose-cells_autofilter.xlsx");
