Problem

The SetCultureInfo method allows you to override the server’s default locale when generating a new Word file from a template with WordWriter. This is especially useful for the display of dates. It is important, however, to understand that any date formatting must be applied to the Word Template Merge Field instead of in the ASP.NET script.

Solution

To see a standard field code for a DateTimeObject merge field, right-click on the field, and choose Toggle Field codes:

 {MERGEFIELD DateTimeObject} 

You can see that there are no formatting switches applied to this field. In this situation, the default format of “yyy-MM-dd HH:mm:ss” (4-digit year, month, day, military hour, minute, second) will be applied. To set the culture info to a particular language, such as German:

CultureInfo deDe = new CultureInfo("de-DE");
wt.CultureInfo = deDe;
For more information see our documentation on WordTemplate.CultureInfo.

Best coding practices

Unexpected date formatting behavior can be prevented by keeping the following in mind: The Word template is expecting to receive the date as a System.DateTime object. If it is passed a String instead of a System.DateTime object, it will not be able to apply the formatting codes and apply the correct Culture settings.
