Hello Kenny,

Thank you for waiting for us.

I've investigated your issue that custom stylings and column widths are not exported to word, excel and pdf.  I'm not sure whether I correctly understand your issue, but when I tried to reproduce your issue, it seems that there were some differences in the results:

- WebExcelExporter: custom styles and column widths are gone in the exported excel file.
- WebWordExporter: custom styles and column widths are gone in the exported word file.
- WebDocumentExporter: custom styles are gone in the exported pdf file while column widths are applied expectedly.

So, I'd like you to understand that my investigation is based on the above results.

[WebExcelExporter]

You would need to apply custom styles and column widths manually by handling *Exported events of WebExcelExporter.  As to column widths, the event to be handled would be GridFieldCaptionExported.  As to custom styles, it would be better to handle CellExported or RowExported because you might want to apply styles to a specific cell.

Here are documents about how to set column widths and how to apply cell styles:

- Column width:
    https://www.infragistics.com/help/aspnet/infragistics.webui.documents.excel~infragistics.documents.excel.worksheetcolumn_members
    --> See the SetWidth method.

 e.Worksheet.Columns[e.CurrentColumnIndex].SetWidth(30, WorksheetColumnWidthUnit.Pixel);

- Cell styles:

    https://www.infragistics.com/help/aspnet/infragistics.webui.documents.excel~infragistics.documents.excel.iworksheetcellformat_members

e.WorksheetRow.Cells[i].CellFormat.Fill = CellFillPattern.CreateSolidFill(Color.PaleVioletRed);
e.WorksheetRow.Cells[i].CellFormat.Font.ColorInfo = Color.White;

[WebWordExporter]

Similarly, you would need to apply custom styles and column widths manually by handling *Exported events -- GridFieldCaptionExported, CellExported or RowExported -- of WebWordExporter.

Here are documents about how to set column widths and how to apply cell styles:

- Column width:
    https://www.infragistics.com/help/aspnet/infragistics.webui.documents.io~infragistics.documents.word.tablecellproperties~preferredwidthaspercentage

e.Cell.Properties.PreferredWidthAsPercentage = 13;

- Cell styles:

    https://www.infragistics.com/help/aspnet/infragistics.webui.documents.word~infragistics.documents.word.tablecell_members

e.TableCell.Properties.BackColor = Color.PaleVioletRed;
((e.TableCell.ContentBlocks[0] as Paragraph).ContentRuns[0] as TextRun).Font.ForeColor = Color.White;

[WebDocumentExporter]

In case of document exporter, it would be better to handle CellExporting event if you would need to apply any styles which cannot be changed through IGridCell interface properties which can be accessible through DocumentCellExportingEventArgs's ReportCellElement property.  In that case, you would need to add elements to be styled, style them and cancel the event.

IText font = e.ReportCellElement.AddText();
font.Style = new Infragistics.Documents.Reports.Report.Text.Style(new Infragistics.Documents.Reports.Graphics.Font("Verdana", 8), Infragistics.Documents.Reports.Graphics.Brushes.White);
font.AddContent(e.GridCell.Text);

e.Cancel = true;

I attached a sample application.  In the sample, there is a WebDataGrid to which custom styles are applied in InitializeRow event.  And each field has its width.  In clicking each export button, you'll get a corresponding exported file and you can see that custom styles and column widths are applied to it.

I hope this will help.
