Dear Telerik support,

My datetime columns arebehaving just the same as you can seein your article here

http://docs.telerik.com/devtools/wpf/controls/radgridview/export/how-to/export-datetime

Then i tried the given solution,but although the event is being called and the Format being attributed with the correct format, the solution doesn't not working for me. My datetime columns cells show as #########

Can you please check my code and see if i am missing something?

private void CustomGridview_ElementExportingToDocument(object sender, GridViewElementExportingToDocumentEventArgs e)
{
    if (e.Element == ExportElement.Cell)
    {
        var cellExportingArgs = e as GridViewCellExportingEventArgs;
        var parameters = cellExportingArgs.VisualParameters as GridViewDocumentVisualExportParameters;
        if (cellExportingArgs.Column.GetType() == typeof(GridViewDataColumn))
        {
            if (((GridViewDataColumn)cellExportingArgs.Column).DataFormatString == "d")
            {
                parameters.Style = new CellSelectionStyle()
                {
                    Format = new CellValueFormat(CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern)
                };
            }
            if (((GridViewDataColumn)cellExportingArgs.Column).DataFormatString == "g")
            {
                parameters.Style = new CellSelectionStyle()
                {
                    Format = new CellValueFormat(CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern + " " + CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern)
                };
            }
        }
    }
}

Thank you

Hello Jacob,

Can you increase the spreadsheet's column width and see if the "#####" changes into the desired output once there is enough space for the content?

I suspect your formatting is working as expected, rather I think you're seeing a known issue where Excel does this for cells with text content wider than available space.

Let us know if this resolves the issue.

Hello Lance,

That actually makes a lot of sense, although I am having the same issue for the pdf as well.

but then this leads me to another issue which I have already opened

http://www.telerik.com/forums/exporting-to-pdf-column-width-issue

once the width is wider, this problem might be solved!

I tested on EXCEL and indeed that was the problem! Ok, then I just need that other case to be solved and I am done

Thank you
