Importing

MindFusion.Spreadsheet can load data from CSV (comma-separated values), XLSX (Office Open XML), ODS (OpenDocument Spreadsheet), and its native binary and XML formats. The files are imported through a set of importer classes: CsvImporter for CSV, ExcelImporter for XLSX, and CalcImporter for ODS. To import a file, create an instance of the respective importer class, set the necessary properties, and call its Import method. The following code demonstrates how to import a workbook from an existing XLSX file:

var excelImporter = new ExcelImporter();
excelImporter.Import(workbook, @"d:\workbook.xlsx");

Importing from CSV can be further facilitated through the use of a built-in CsvImportForm. The form provides the user interface to enter various options and preview the data before it is actually imported.

Exporting

MindFusion.Spreadsheet can export data to a variety of formats, including image, PDF, CSV, XLSX, ODS, HTML and MHTML. In addition the workbooks can be previewed and printed to paper and XPS. The workbooks and worksheets are exported through a set of exporter classes: ImageExporter for images, PdfExporter for PDF, CsvExporter for CSV, ExcelExporter for XLSX, CalcExporter for ODS, HtmlExporter for XHTML, and so on. Printing is done through the WorkbookPrinter class. To export a workbook, create an instance of the respective exporter class, set the necessary properties, and call the Export method. The following code demonstrates how to export a workbook to ODS:

var calcExporter = new CalcExporter();
calcExporter.Export(workbook, @"c:\mysheet.ods");

The following image illustrates a workbook exported to an XHTML file using the HtmlExporter class:

WinForms.Spreadsheet: Sorting Data

In this blog we will discuss how to sort existing data in MindFusion.Spreadsheet for WinForms both programmatically and by using the built-in form.

Introduction

As with all previous blogs we start off by creating a new Windows Forms Application in Visual Studio and adding a WorkbookView control to the main form. The WorkbookView displays a Workbook with a single worksheet.

Initializing the data

The data that should be sorted is contained in an CSV (comma-separated value) file, which is loaded at the start of the application. Some minor formatting is applied to the imported data, such as emphasizing the header row. The columns are automatically resized to fit the content through the ResizeColumnsToFit method of the WorkbookView class.

Sorting programmatically

The sorting is performed by calling the Sort method of the Worksheet class and providing a SortOptions object. This object contains information about the sort, such as which row or column to sort by, the sort direction (horizontal or vertical) and so on. In this particular case, we sort the data by columns, therefore we specify TopToBottom for the sort direction:

sortOptions.Direction = SortDirection.TopToBottom;

The columns (or rows) to sort by are specified by SortKey objects, added to the Keys collection of the SortOptions class. The order of the keys in the collection is important. For example, to sort by the first column and then by the fourth column, we define the following keys:

sortOptions.Keys.Add(new SortKey(0));
sortOptions.Keys.Add(new SortKey(3));

The Sort method accepts as argument the range to be sorted. In this sample we would like to prevent the header row from being sorted and specify A2:D15 for the target range.

The following image shows the running sample:

Sorting through the built-in form

Sorting can also be performed through the built-in SortForm form, contained in the MindFusion.Spreadsheet.WinForms.StandardForms.dll assembly. The image below displays the form with the first and fourth columns selected as sort keys:
