excelConverter.ExcelVersion = ExcelVersion.Excel97to2003; 
excelConverter.ExportToExcel(this.gridGroupingControl1, saveFileDialog.FileName, exportingOptions);

Dim excelConverter As GridGroupingExcelConverterControl = new GridGroupingExcelConverterControl()
' If .xls extension then make use of this code 
excelConverter.ExcelVersion = ExcelVersion.Excel97to2003
excelConverter.ExportToExcel(Me.gridGroupingControl1, saveFileDialog.FileName, exportingOptions)
