紧急 ！！！使用OpenXML将DataValidation列表类型添加到Excel列 [英] URGENT !!! Add DataValidation List Type to Excel column using OpenXML

问题描述

你好

我编写了一个从Dataset制作Excel文件的功能.一切正常.

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

但是，要求是

-需要保留几列，只读给客户端.

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

-另外，在一列中创建列表，以便客户端只能为该列选择可能的值.

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

我无法使用OpenXml做到这一点.

I am not able to achieve this with OpenXml.

下面是我的从DataSet生成Excel文件的代码.

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);
                    }
                
                }
            }
        }
