We have released version 1.6 of MindFusion.Spreadsheet for WinForms. The new version includes:

Improved XLSX Import and Export
The ExcelExporter and ExcelImporter classes are now times faster than before and the results are more accurate. Various problems and inconsistencies were fixed. Both classes now expose a View property. If you set the View property of the ExcelExporter, the exporter will also export view information, such as the active tab and selection. Alternatively, setting this property during import, will cause the view information to be imported.

Miscellaneous

• The CsvExporter class can now export partial worksheets through the new Export overload.
  
• The ImageExporter can take into consideration the worksheet zoom through the new EnableZoom property.
  
• The WorkbookPrinter now exposes a Landscape property, which can be used to specify page orientation.
  
• The WorkbookView expoxes new Cut, Copy, and Paste methods, which can be used to cut, copy, and paste the current selection of the active worksheet in the view.
  
• The WorkbookView now exposes ColumnsMoving and RowsMoving events, which can be used to validate interactive columns and rows moving.
  
• The WorkbookView now exposes ColumnsResizing and RowsResizing events, which can be used to validate interactive columns and rows resizing.
