Add PDF Bookmarks with Named Destinations

Aspose.Cells supports to specify Named Destinations in the output PDF file that do not depend on PDF pages. It means, if pages are added or deleted from PDF, bookmarks may become invalid but named destinations will remain intact. To create Named Destination, please set the PdfBookmarkEntry.DestinationName property.

//Load source Excel file
Workbook wb = new Workbook("Book1.xlsx");
//Access first worksheet
Worksheet ws = wb.Worksheets[0];
//Access cell C5
Cell cell = ws.Cells["C5"];
//Create Bookmark and Destination for this cell
PdfBookmarkEntry bookmarkEntry = new PdfBookmarkEntry();
bookmarkEntry.Text = "Text";
bookmarkEntry.Destination = cell;
bookmarkEntry.DestinationName = "AsposeCells--" + cell.Name;
//Access cell G56
cell = ws.Cells["G56"];
//Create Sub-Bookmark and Destination for this cell
PdfBookmarkEntry subbookmarkEntry1 = new PdfBookmarkEntry();
subbookmarkEntry1.Text = "Text1";
subbookmarkEntry1.Destination = cell;
subbookmarkEntry1.DestinationName = "AsposeCells--" + cell.Name;
//Access cell L4
cell = ws.Cells["L4"];
//Create Sub-Bookmark and Destination for this cell
PdfBookmarkEntry subbookmarkEntry2 = new PdfBookmarkEntry();
subbookmarkEntry2.Text = "Text2";
subbookmarkEntry2.Destination = cell;
subbookmarkEntry2.DestinationName = "AsposeCells--" + cell.Name;
//Add Sub-Bookmarks in list
ArrayList list = new ArrayList();
//Assign Sub-Bookmarks list to Bookmark Sub-Entry
bookmarkEntry.SubEntry = list;
//Create PdfSaveOptions and assign Bookmark to it
PdfSaveOptions opts = new PdfSaveOptions();
opts.Bookmark = bookmarkEntry;
//Save the workbook in Pdf format with given pdf save options
wb.Save("out1.pdf", opts); 

Please see the document/article (with attachments) that explains on how to add PDF Bookmarks with Named Destinations for your complete reference.

Control loading of External Resources in MS Excel Workbook while rendering to PDF

If your Excel file contains external resources(linked images or objects), so, when you convert your Excel file to Pdf, Aspose.Cells retrieves these external resources and renders them to Pdf file format. Now, if you do not want to load these external resources rather you want to manipulate them, you can do this using PdfSaveOptions.StreamProvider API which implements the IStreamProvider interface. For more detail, please see this article.

Copy VBA Macro UserForm DesignerStorage from Template to Target Workbook

Aspose.Cells allows you to copy VBA project from one Excel file into other. VBA project consists of various types of modules i.e. Document, Procedural, Designer etc. All modules can be copied with simple code but for Designer module, there is some extra data called Designer Storage needs to be accessed or copied. For more detail, please see this article.

Send Shape Front or Back inside the Worksheet

Aspose.Cells provides Shape.ToFrontOrBack()method which changes the z-order position of the shape. If you want to send shape to back you will use negative number like -1, -2, -3 etc. and if you want to send shape to front, you will use positive number like 1, 2, 3 etc. For more detail, please see this article.

Sort Data in Column with Custom Sort List

You can sort data in the column using custom list. This can be done using DataSorter.AddKey(int key, SortOrder order, String customList) method. However, this method works only if the items in custom list do not have commas inside them. If they have commas like “USA,US”, “China,CN” etc., then you must use DataSorter.AddKey(int key, SortOrder order, String[] customList) method. Here the last parameter is not String but Array of Strings. For more detail, please see this article.

Create Remove and Get GridCell Comments

GridWeb displays comments as Tooltips like MS-Excel does when you hover mouse over the respective cell. The web based grid control provided by Aspose.Cells for .NET allows you to create, remove and get cell comments inside the worksheet. For more detail, please see this article.
