Aspose development team is pleased to announce the new release of Aspose.Cells for .NET 18.1.0. It has added some useful features and enhancements regarding Pivot Tables, Charts and Excel to HTML renderings. The previous versions has create PdfBookmarkEntry for normal sheets only. But now Aspose.Cells can also create PdfBookmarkEntry for chart sheet. Since, chart sheet does not have any other cell except cell A1, so it will create PdfBookmarkEntry for cell A1 only. The following sample code loads an Excel file which has four sheets in it. Two of them are normal sheets and others are chart sheets. It creates four bookmarks, one for each sheet. Microsoft Excel file may contain many unnecessary unused styles. When users export the Excel file to HTML file format, these unused styles are also exported. This could increase the size of HTML. Users can exclude the unused styles during the conversion of Excel file to HTML using the HtmlSaveOptions.ExcludeUnusedStyles property. When Microsoft Excel file is exported to HTML using Microsoft Excel or Aspose.Cells APIs, it also exports various types of Document, Workbook and Worksheet properties. Users can avoid exporting these properties by setting the HtmlSaveOptions.ExportDocumentProperties, HtmlSaveOptions.ExportWorkbookProperties and HtmlSaveOptions.ExportWorksheetProperties as false. The default value of these properties is true. A Pivot table may use other pivot table as a data source. Such a Pivot table is called a child or nested Pivot table to its parent Pivot table. You can find the children Pivot tables for a parent Pivot table using the PivotTable.GetChildren() method. When users create a Pivot Table, Microsoft Excel takes a copy of the source data and stores it in the Pivot Cache. The Pivot Cache is held inside the memory of Microsoft Excel. When users load an Excel file inside the Workbook object, users can decide whether it also want to load the records of Pivot Cache or not, using the LoadOptions.ParsingPivotCachedRecords property. The default value of this property is false. If Pivot Cache is quite big, it can increase the performance. Aspose.Cells.GridDesktop has introduced two new events i.e. AfterDeleteColumns and AfterDeleteRows. These events are fired when you delete column(s) and row(s) respectively. There are some other enhancements also included in this release, such as Handle Automatic Units of Chart Axis like Microsoft Excel, Render Interactive Scrollbar in GridWeb, Handled IndexOutOfRangeException while converting XLSX to HTML, Handled exception when rendering image of the chart and Handled an exception when setting HtmlString on a cell to specific value. This release has also fixed several important bugs and other issues, for example, issues around reading/writing MS Excel file formats, manipulating Ole Objects in Excel file, rendering Excel to HTML and vice versa, converting SpreadsheetML to XLSX, import custom objects to Excel sheet, rendering and manipulating charts, manipulating PivotTables, rendering images from Excel worksheets, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved.
