A format is set to a cell like : ,
If we set value directly like : mmmm-yyworksheet.Cells["B5"].Value = new DateTime(2015, 12, 25, 00, 00, 00); => OK
if we set value through Offset like
worksheet.Cells["B4"].Offset(1, 0).Value = new DateTime(2015, 12, 25, 00, 00, 00); => NumberFormat is lost and reset
Best regards

Hi,
Please note that the Offset method returns a range instead of a certain cell and the Range.Value property is not the same as the Cell.Value property. If set the Range.Value property to the DateTime value then the NumericFormat of this cell is changed to the current culture's default DateTime format. I suggest you use the following code to set Range.Value property so its NumericFormat is not changed:
C#worksheet.Cells["B4"].Offset(1, 0).Value = CellValue.FromDateTime(new DateTime(2015, 12, 25, 00, 00, 00), false).NumericValue;
If you need further assistance, let me know.
Hi George,
I'm not agree with you. Cell inherit from Range.
worksheet.Cells["B5"].Value is a
public abstract CellValue Value { get; set; }
in class Range
An produce no problem.
worksheet.Cells["B4"].Offset(1, 0).Value is a:
public abstract CellValue Value { get; set; }
in class Range
And produce the problem.
And this problem is not limited to Date, number format is impacted too.
To Finish, if offset function api have some side effect, it is not very good. In both situation we get a CellValue… How could we know? set a value, doesn't impact format in a range or cell in Excel.
Inheritance behaviour must not have side effect on any other property outside…
And logically, why on Range.Value, underlying Cell.Value is not call?
Best regards,
Alexandre
