Set column width dynamically while exporting DATA ONLY to excel in c# using crystal report (ExportFormatType.ExcelRecord)

Question

I am using the below code

// Declare variables and get the export options.
ExportOptions exportOpts = new ExportOptions();
ExcelFormatOptions excelFormatOpts = new ExcelFormatOptions();
DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
exportOpts = rpt.ExportOptions;

// Set the excel format options.
excelFormatOpts.ExcelConstantColumnWidth = 100;
excelFormatOpts.ExcelUseConstantColumnWidth = true;
exportOpts.ExportFormatType = ExportFormatType.ExcelRecord;
exportOpts.FormatOptions = excelFormatOpts;

// Set the disk file options and export.
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
diskOpts.DiskFileName = strFilename;
exportOpts.DestinationOptions = diskOpts;

rpt.Export();

I am getting the data's exported to excel correctly without formating.

Question: Now I need to format. I want to set column width in the excel.

Can I do it?

From my above code the below lines seems not to function

excelFormatOpts.ExcelConstantColumnWidth = 100;
excelFormatOpts.ExcelUseConstantColumnWidth = true;

I appreciate any help in this regard as this issue is eating my time.

Answer 1

i am assuning that you have excel worksheet object with a name esheet.

esheet.Cells.Style.EntireColumn.AutoFit();

try this.

Answer 2

I see two problems in your code.

1. With ExportFormatType.ExcelRecord you should use ExcelDataOnlyFormatOptions class, not ExcelFormatOptions. ExcelFormatOptions corresponds to ExportFormatType.Excel

2. ExcelConstantColumnWidth in C# version is in twips and 100 is very small value. You should multiply it by 20.

I managed to get working code for ExportFormatType.Excel case, but not for ExportFormatType.ExcelRecord. Other properties of ExcelDataOnlyFormatOptions work, but ExcelConstantColumnWidth still doesn't work for me.
