export to excel in asp.net using openxml

Question

Привет всем, я работаю над проектом, который требует, чтобы я экспортировал некоторые данные, чтобы выделить на кнопке , используя открытый xml. Вот класс, который я использую для экспорта в excel :

и это функция кнопки мыши:

protected void Button1_Click(object sender, EventArgs e) 
     { 
      string qwe = TextBox1.Text; 
      string ert = TextBox2.Text; 
      string filename = @"D:\\ExcelOpenXmlWithImageAndStyles.xlsx"; 
      CreateExcelOpen exp = new CreateExcelOpen(); 
      exp.BuildWorkbook1(filename); 
     } 

здесь мои требования:

. Мне нужно передать значения двух текстовых полей в две ячейки (которые теперь содержат значения 12334 и 124515).

. Столбец заголовка не настраивается для размещения значений, которые я предоставил (группа розничных клиентов и т. Д.). Пожалуйста, предложите модификации , требуемые для этого класса, чтобы включить автоподтверждение.

спасибо.

Answer 1

в методе CreateContent вы жестко запрограммированные значения, такие как:

c.CellValue = new CellValue("12334"); 

изменения его значения текстовых полей, которые вы хотите показать.

для установки ширины заголовков, вам придется добавить столбцы вместе с клетками, как вам нужно столбцов, чтобы определить ширину следующей статье будет иметь некоторую помощь для вас:

Answer 2

Я потратил много времени на поисковые запросы, связанные с OpenXml. Наконец-то я нашел решение своих проблем, объединив функции OpenXml с Excel VBA. Итак, У меня есть Excel - файл с поддержкой макроса (xlsm) в качестве шаблона для моего проекта. Независимо от логики, которую трудно реализовать в OpenXml, я перешел в VBA. Для кнопкуШирина, например это так же просто, как:

Sub Workbook_Open() ActiveSheet.Columns.AutoFit End Sub

Надеется, что это может помочь.

Answer 3

Я написал свой собственный экспорт в Excel writer. Он быстрый и позволяет существенно форматировать ячейки. Вы можете просмотреть его на

Я надеюсь, что это помогает.
