Online PR News – 21-July-2016 – Lane Cove, NSW – What is new in this release?

We are pleased to announce the new release of Aspose.Cells for .NET 8.8.3. This release includes many valuable features, other enhancements and critical bug fixes. It also improves the overall stability and usability of the APIs. Aspose.Cells APIs have provided the ability to add & manipulate the ActiveX Controls in spreadsheets. Aspose.Cells for .NET API has exposed a number of useful classes, enumerations and methods to fully support the ActiveX Controls. The most worth mentioning addition to the public API is the ShapeCollection.AddActiveXControl method which allows adding an ActiveX Control to the collection of shapes by accepting 7 parameters to specify the control type, location to place the control and size of the control. Below provided code snippet demonstrates the simple usage scenario of newly exposed a method to add an ActiveX Control of type Toggle Button. Please check the detailed article on Adding ActiveX Controls to Worksheets if you wish to get more in-depth understanding of the aforementioned feature. Aspose.Cells APIs provide the ability to export spreadsheet contents in HTML format as per the standards opted by Excel application. If a spreadsheet is converted to HTML using Excel application, it does not render the grid lines. Aspose.Cells APIs behave in the same way using its default settings, however, with this release of the API, the developers can now choose to render the grid lines as well. Aspose.Cells for Java API has exposed a property with default value of false. If the said property is set to true, the API renders the grid lines for the available data range in HTML format. Below provided code snippet demonstrates the simple usage scenario of newly exposed HtmlSaveOptions.ExportGridLines to render the grid lines to HTML format. It has exposed the OleObject.AutoLoad property which allows refreshing the OleObject’s image if the contents/data of the underlying object has been changed. The aforementioned property when set to true, forces the Excel application to refresh the OleObject’s image when resultant spreadsheet is loaded in Excel interface. Aspose.Cells APIs now allow to get and set the comments for an instance of ListObject. In order to provide the aforementioned feature, the Aspose.Cells APIs have exposed the ListObject.Comment property with this release. In this release, several important issues have been addressed. For example, issues around reading and writing Microsoft Excel file formats, manipulating shapes, copying Rows/Columns, manipulating PivotTables, converting spreadsheets to HTML files and vice versa, manipulating and rendering charts and shapes, rendering images from Excel worksheets, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved.
