Adding numbered list in existing table in Word using Open XML

While working with OpenXML, I need to update an existing word template document with some bullet list. The template and required formatting follow following points:

• The document template consists of several tables
• In 1 of its table, we need to insert a row with bullet list content

Issue: We can easily create table, add rows in existing document template but adding bullet list in a row is somewhat challenging and I consumed a day to complete it. Sharing the concept may save others time :)

I am taking part of my solution to explain the code. Below table is the part of my document template which i need to update.

UniqueTableName

Please refer following

·         One

·         TwoPlaceHolder:

·         RowToRemove

Note: Some text here

In the above table, the requirement is to add a row under TwoPlaceHolder and with 1 indent and based on certain condition the RowToRemove is to be deleted. 

Note : All bullets in above table are as table row of which border style has been set to none. I am jumping directly to required code for this without explaining any OpenXml namespace, assuming the reader knows about them.

Here, the GenerateDocument method takes the path of source and destination files as parameter and the other 2 parameters are for updating the document. 

Note: the method updates the document at the given source location only. 

       

private string GenerateDocument(string sourceFile, string destinationFile, bool isRowDelete, List<string> selectedItems)         {             System.IO.File.Copy(sourceFile, destinationFile, true);        using (var document = WordprocessingDocument.Open(destinationFile, true))        {          string documentText = null;          using (StreamReader sr = new StreamReader(document.MainDocumentPart.GetStream()))                 {                     documentText = sr.ReadToEnd();                 }                           Body documentBody = document.MainDocumentPart.Document.Body;                 foreach (Table documentTable in documentBody.Descendants<Table>().                  Where(tbl => tbl.InnerText.Contains("UniqueTableName")))                 {                     if (selectedItems.Count > 0)                     {                       var secondRow = documentTable.Descendants<TableRow>().Where(tr => tr.InnerText.                                 Contains("TwoPlaceHolder")).FirstOrDefault();                         TableRow newRow = new TableRow();                         TableCell newcell = new TableCell();                         foreach (string item in selectedItems)                         {                          //Adding the bulleted list dynamically                              Paragraph para = new Paragraph                                 (new ParagraphProperties(                                     new NumberingProperties(                                        new NumberingLevelReference() { Val = 1 },                                        new NumberingId() { Val = 2 })),                                        new Run(                                         new RunProperties(),                                         new Text(item) { Space = SpaceProcessingModeValues.Preserve }));                             newcell.Append(para);                         }                         newRow.Append(newcell);                         secondRow.InsertAfterSelf(newRow);                     }                     if (isRowDelete)                     {                        //removing the row                        var rowForDelete = documentTable.Descendants<TableRow>().Where(tr => tr.InnerText.                             Contains("RowToRemove")).FirstOrDefault();                         rowForDelete.Remove();                     }                 }          Regex regexTablename = new Regex("UniqueTableName");   documentText = regexTablename.Replace(documentText, HttpUtility.HtmlEncode("Edited Bullet List"));     using (StreamWriter sw = new        StreamWriter(document.MainDocumentPart.GetStream(FileMode.Create)))                 {                     sw.Write(documentText);                 }             }             return destinationFile;         }

After executing this method, open the document from its source location, you will see the edited table as below:

Edited Bullet List

·        One

·        TwoPlaceHolder:

o    This is first Item o     This is second Item o     This is third Item o     This is forth Item o     This is fifth Item o     This is sixth Item o     This is seventh Item

Note: Some text here.

Result:

• The table title has been replaced by new Title "Edited Bullet List".
• New seven items have been inserted below TwoPlaceHolder row
• The "RowToRemove" has been removed from the table
