Hi,

 I would like add the ultrawebgrid export with UltraWebGridExcelExport in a excel template like this :

    Workbook oTemplate = Infragistics.Excel.Workbook.Load("Template.xls");  

    Worksheet ws = oTemplate.Worksheets.Add("deals");

    ExcelDealExporter.Export(dealsBlotter, ws);

I have this error :

 [NullReferenceException: Object reference not set to an instance of an object.] Infragistics.Excel.Serialization.EscherRecords.ClientData.Save(WorkbookSerializationManager manager) +161 Infragistics.Excel.Serialization.EscherRecords.EscherRecordContainerBase.Save(WorkbookSerializationManager manager) +107 Infragistics.Excel.Serialization.EscherRecords.EscherRecordContainerBase.Save(WorkbookSerializationManager manager) +107 Infragistics.Excel.Serialization.EscherRecords.EscherRecordContainerBase.Save(WorkbookSerializationManager manager) +107 Infragistics.Excel.Serialization.BiffRecords.MSODRAWINGRecord.Save(WorkbookSerializationManager manager) +34 Infragistics.Excel.Serialization.WorkbookSerializationManager.WriteRecord(BIFFType type) +108 Infragistics.Excel.Serialization.WorkbookSerializationManager.WriteWorksheetRecords(Worksheet worksheet, Boolean hasShapes) +546 Infragistics.Excel.Serialization.WorkbookSerializationManager.Save() +271 Infragistics.Excel.Workbook.Save(Stream stream) +706 Infragistics.Excel.BIFF8Writer.WriteWorkbookToStream(Workbook workbook, Stream outStream) +14

  
 I don't understand why ...
