我无法使用epplus使用生成的Excel将日期过滤为月，年，日期

Question

I have a view, from which I filter data and show the search results, I changed the Date format to

convert(varchar(11),getdate(),113) 

This is the format in view

After downloading in excel, it is just giving all dates. No grouping is available. I tried several formatting to change the date format in Excel as well as code like

ews.Column(i).Style.Numberformat.Format = "d-mmm-yy";

but no use.

My View returns date like 19 Mar 2014

I want grouping of date with format as 19-Mar-2014

Please suggest me a working answer.

Answer 1

Don't do any conversion in the view, eg just have it return getdate() and set the format in EPPlus code. I use this for one of my projects and it will allow selection / format correctly in Excel going this route.

I agree with Jordan in that you should not format the date within the database, but return it to your .NET code as a SQL DATETIME, C# DateTime. If you do that, you have more control over how you can write it into the spreadsheet.

var file = new FileInfo(@"C:\Temp\ExcelDemo.xlsx");
using (var package = new ExcelPackage(file))
{
    var worksheet = package.Workbook.Worksheets.Add("Demo");

    var date = DateTime.Now;
    worksheet.Cells[1, 1].Value = @"Date Raw";
    worksheet.Cells[1, 2].Value = @"Date Raw with Style.Numberformat.Format = ""D-MMM-YY""";
    worksheet.Cells[1, 3].Value = @".ToString()";
    worksheet.Cells[1, 4].Value = @".ToString(dd MMM yy)";
    worksheet.Cells[1, 5].Value = @".ToString(yyyy-MM-ddTHH\:mm\:ss.fffffffzzz)";

    worksheet.Column(2).Style.Numberformat.Format = "D-MMM-YY";

    worksheet.Cells[2, 1].Value = date;
    worksheet.Cells[2, 2].Value = date;
    worksheet.Cells[2, 3].Value = date.ToString();
    worksheet.Cells[2, 4].Value = date.ToString(@"dd MMM yy");
    worksheet.Cells[2, 5].Value = date.ToString(@"yyyy-MM-ddTHH\:mm\:ss.fffffffzzz");

    package.Save();
}

select replace(convert(varchar(11),getdate(),113),' ','-')
