Aspose.Cells for .NET logo

We are pleased to announce the release of Aspose.Cells for .NET v18.3. Please check the [document][2] on how to install Aspose for .NET APIs directly from NuGet repository. In this release, we have added some worthy features and other enhancements for the users. Please check the [release notes][3] in order to get an idea about what is new and what has been enhanced or fixed with this revision of Aspose.Cells for .NET.

Access and Modify the Display Label of the Linked Ole Object

Microsoft Excel allows you to change the display label of the Ole Object. You can also access or modify the display label of the Ole object via Aspose.Cells APIs using the OleObject.Label property. The following sample code loads an Excel file that contains the Ole Object. The code accesses the Ole Object and changes its Label. Please notice the console output that will show the effect of the sample code.

Please see the document/article with attachment(s) on how to access and modify the display label of the linked Ole Object for your reference.

Group Pivot Fields in the Pivot Table

Microsoft Excel allows you to group pivot fields in the Pivot Table. When there is a large amount of data related to a pivot field, it is better to group them into sections. Aspose.Cells provides this feature via the PivotTable.SetManualGroupField() method. This was a long-awaited feature requested by many users. The following sample code loads the template Excel file and performs grouping operation on the first pivot field in the Pivot Table using the PivotTable.SetManualGroupField() method.

Please see the document/article with attachment(s) on how to group pivot fields in the Pivot Table for your reference.

Export Similar Border Style when Border Style is not Supported by Web Browsers

Microsoft Excel also supports dashed border types that are not supported by most web browsers. When you convert such an Excel file into HTML using Aspose.Cells, the borders are removed. However, Aspose.Cells allows you to accomplish the task and supports to display such borders with HtmlSaveOptions.ExportSimilarBorderStyle property. For more detail on the feature, please see this article/document for your reference.

Find if the Worksheet is a Dialog Sheet

Dialog sheet is an older format that contains a dialog box. You can find if a sheet is a dialog or some other type with Worksheet.Type property. If it returns enumeration value SheetType.Dialog, then it means, you are dealing with Dialog sheet. For more detail, please see this article.

Preserve Single Quote Prefix of Cell Value or Range

When you put some value inside a cell that has leading apostrophe or single quote mark, then Microsoft Excel hides it, but when you select the cell, it displays the leading apostrophe or single quote in a formula bar. Aspose.Cells provides StyleFlag.QuotePrefix property that will handle either preserving the quote or not preserving the quote for your needs. For more detail, please see this article.

Change the Decimal Separator from Numeric Keypad

By default, Aspose.Cells.GridWeb (similar to MS Excel) displays numeric data accordingly based on the locale/regional settings on the machine. You can change the decimal separator from Numeric keypad programmatically using Aspose.Cells.GridWeb API. So, when a file is imported into GridWeb matrix or you input some numeric data (from the numeric keypad) into a new worksheet cell, it should have your desired decimal separator set visually. For more detail, please see this article.
