InfragisticsWorksheetCell.GetText() throws exception for cell with custom format #/#### "SF"


I wanted to document an exception I am seeing when using the Excel library to read a specific custom cell format.

If an Excel cell has the following:

  • Value                                     .001
  • Custom Format                 #/#### "SF"
  • Excel displays                  1/1000 SF

Then reading the cell with InfragisticsWorksheetCell.GetText() throws the following exception:
System.InvalidOperationException was caught
Message=The cell's format string is invalid. To be notified of this when the FormatString is set, set Workbook.ValidateFormatStrings to True.

at Infragistics.Documents.Excel.WorksheetRow.GetCellTextInternal(WorksheetCellBlock cellBlock, GetCellTextParameters parameters)
at Infragistics.Documents.Excel.WorksheetCell.GetText(TextFormatMode textFormatMode)

The following file is a minimal spreadsheet that reproduces the issue with the custom format applied to cell A1:

Thanks for consideration of this issue, and your continued improvements and updates to the Winforms Excel library!
