URGENT !!! Add DataValidation List Type to Excel column using OpenXML RRS feed

  • Question

  • Hello,

    I have written one function to make Excel file from Dataset. It is working fine.

    But, requirement is,

    - Need to make few columns Read only to the client.

    - Also, create List in one column, so that client can only select possible values(Verified,NotVerified) for that column.

    - Set AutoFit to all the columns.

    I am not able to achieve this with OpenXml.

    Below is my code to generate Excel file from DataSet.

    public void ExportDataSet(DataSet ds, string destination)
            {
    
                using (var workbook = SpreadsheetDocument.Create(destination, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
                {
                    var workbookPart = workbook.AddWorkbookPart();
    
                    workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
    
                    workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();
    
                    foreach (System.Data.DataTable table in ds.Tables)
                    {
    
                        var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
                        var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData();
    
                        // Add stylesheet
                    //WorkbookStylesPart stylesPart = workbook.WorkbookPart.AddNewPart<WorkbookStylesPart>();
                    //stylesPart.Stylesheet = GenerateStyleSheet();
                    //stylesPart.Stylesheet.Save();
    
                        sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData);
    
                        DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
                        string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);
    
                        uint sheetId = 1;
                        if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)
                        {
                            sheetId =
                                sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1;
                        }
    
                        DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = table.TableName };
                      
                        sheets.Append(sheet);
    
                        DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
    
                        List<String> columns = new List<string>();
    
    
                       foreach (System.Data.DataColumn column in table.Columns)
                        {
                            columns.Add(column.ColumnName);
                            DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                            cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                            cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(column.ColumnName);
                           
                            headerRow.AppendChild(cell);
                        }
    
                        sheetData.AppendChild(headerRow);
    
                    
    
                        foreach (System.Data.DataRow dsrow in table.Rows)
                        {
                            DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
                            foreach (String col in columns)
                            {
                                DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                                cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                                cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); //
                                newRow.AppendChild(cell);
                            }
    
                            sheetData.AppendChild(newRow);
                        }
                    
                    }
                }
            }
