How to: Use a Custom Converter for Export to a DataTable

The DataTableExportOptions.CustomConverters property enables you to specify a custom converter for a specific DataTable column. To do this, create a class that implements the ICellValueToColumnTypeConverter interface. The ICellValueToColumnTypeConverter.Convert method should perform the required conversion. Subsequently, add an instance of a custom converter to the collection of custom converters available via the DataTableExporter.Options.CustomConverters notation using the Add method.

The Convert method is called for each cell that is exported to the specified column.

The following code snippet illustrates the technique. The converter transforms DateTime values into strings in MMMM-yyyy format, and displays the "N/A" text if a cell contains an error.
