Crash when using the new XamGridExcelExporter
posted

Hi,

I upgraded my project to v11.2 and I'm trying to export the content of my xamGrid with the new xamGridExcelExporter.

Here is my code:

        private void bt_excel_Click(object sender, RoutedEventArgs e)
        {
            Workbook dataWorkbook = new Workbook();
            Worksheet sheetOne = dataWorkbook.Worksheets.Add("Data Sheet");

            dataWorkbook.SetCurrentFormat(WorkbookFormat.Excel2007);

            excelExporter.Export(this.datagrid, dataWorkbook);
           
            SaveExport(dataWorkbook);
        }

        private void SaveExport(Workbook dataWorkbook)
        {
            SaveFileDialog dialog;

            dialog = new SaveFileDialog { Filter = "Excel files|*.xlsx", DefaultExt = "xlsx" };


            bool? showDialog = dialog.ShowDialog();
            if (showDialog == true)
            {
                using (Stream exportStream = dialog.OpenFile())
                {
                    dataWorkbook.Save(exportStream);
                    exportStream.Close();
                }

            }
        }

 

 

Here is the error detail:
