This makes sense since Excel will not store a value for a cell that is null. If you open your file using the Open XML SDK 2.0 Productivity Tool and traverse the XML down to the cell level you will see that only the cells that have data are going to be in that file. … Read more
Embedding Foreign Objects (PDF, TXT, GIF, etc…) into Microsoft Word using OpenXml 2.0 (Well, in collaboration with COM) I got a lot from this site, so here I asked and answered my own question in order to give back a little on a topic in which I had difficulty finding answers on, hope it helps … Read more
Here’s my approach after using you guys as inspiration: IDictionary<String, BookmarkStart> bookmarkMap = new Dictionary<String, BookmarkStart>(); foreach (BookmarkStart bookmarkStart in file.MainDocumentPart.RootElement.Descendants<BookmarkStart>()) { bookmarkMap[bookmarkStart.Name] = bookmarkStart; } foreach (BookmarkStart bookmarkStart in bookmarkMap.Values) { Run bookmarkText = bookmarkStart.NextSibling<Run>(); if (bookmarkText != null) { bookmarkText.GetFirstChild<Text>().Text = “blah”; } }
I recommend installing the Open XML 2.5 productivity tool. Then create a blank Excel document that contains the border and color you desire. Open that file in the productivity tool and then click reflect code. It will then give you the C# code that is required to produce that border and background color. The code … Read more
spreadSheet.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true; spreadSheet.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true; Works for me!
If you use a MemoryStream you can save the changes to a new file like this: byte[] byteArray = File.ReadAllBytes(“c:\\data\\hello.docx”); using (MemoryStream stream = new MemoryStream()) { stream.Write(byteArray, 0, (int)byteArray.Length); using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(stream, true)) { // Do work here } // Save the file with the new name File.WriteAllBytes(“C:\\data\\newFileName.docx”, stream.ToArray()); }
The s attribute references a style xf entry in styles.xml. The style xf in turn references a number format mask. To identify a cell that contains a date, you need to perform the style xf -> numberformat lookup, then identify whether that numberformat mask is a date/time numberformat mask (rather than, for example, a percentage … Read more
All strings in an Excel worksheet are stored in a array like structure called the SharedStringTable. The goal of this table is to centralize all strings in an index based array and then if that string is used multiple times in the document to just reference the index in this array. That being said, the … Read more
You cannot reference OOXML content via page numbering at the OOXML data level alone. Hard page breaks are not the problem; hard page breaks can be counted. Soft page breaks are the problem. These are calculated according to line break and pagination algorithms which are implementation dependent; it is not intrinsic to the OOXML data. … Read more
I wrote this quick example. It works for me. I only tested it with one dataset with one table inside, but I guess that may be enough for you. Take into consideration that I treated all cells as String (not even SharedStrings). If you want to use SharedStrings you might need to tweak my sample … Read more
