I have some problem with Export to Excel for DateTime Format Columns.
Set Column Format:
If I set DateFormatString, the export to Excel is wrong. It export the value as String and Excel cannot recognize the DateTime column.
If i remove DateFormatString on Exporting and on Exported I set the DateFormat string, the Excel is right but the first line no!
I think that is a bug? My WPF version is: 2018.1.220.40
Thank you very much
