I have some problem with Export to Excel for DateTime Format Columns.

Set Column Format:

(this.myGrid.Columns["JPr_MinStart"] as GridViewDataColumn).DataFormatString = "dd/MM/yyyy hh:mm";


On ElementExportingToDocument:

01.private void myGrid_ElementExportingToDocument(object sender, GridViewElementExportingToDocumentEventArgs e)
03.    if (e.Element == ExportElement.Cell)
04.    {
05.        var cellExportingArgs = e as GridViewCellExportingEventArgs;
06.        if (
07.            (cellExportingArgs.Column as GridViewDataColumn).UniqueName == "JPr_MinStart"
08.        )
09.        {
10.            (cellExportingArgs.Column as GridViewDataColumn).DataFormatString = string.Empty;
11.            var parameters = cellExportingArgs.VisualParameters as GridViewDocumentVisualExportParameters;
12.            parameters.Style = new CellSelectionStyle()
13.            {
14.                Format = new CellValueFormat("dd/MM/yyyy hh:mm")
15.            };
16.        }
17.    }

On ElementExportedToDocument

private void myGrid_ElementExportedToDocument(object sender, GridViewElementExportedToDocumentEventArgs e)
         if (e.Element == ExportElement.Table)
      (this.myGrid.Columns["JPr_MinStart"] as GridViewDataColumn).DataFormatString = "dd/MM/yyyy hh:mm";


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

Hello Alessandro,

This behavior is addressed in the Export DateTime Value article. I hope it helps.
