I am using Free Spire.net. I am using below code to refresh Pivotal table. Facing issue while executing the code.

Worksheet ptsheet = workbook.Worksheets["Quality Summary"];

string rangeValue = "A1:N" + Convert.ToDouble(dsallReportData.Tables["QualityData"].Rows.Count + 1);
CellRange dataRange = sheetQualityData.Range[rangeValue];

workbook.NameRanges["Table2"].RefersToRange = sheetQualityData.Range[1,1, sheetQualityData.LastRow, sheetQualityData.LastColumn];


//Get the PivotTable that was built on the data source
XlsPivotTable pt = ptsheet.PivotTables["ptSummary"] as XlsPivotTable;

//Refresh the data of PivotTable
pt.Cache.IsRefreshOnLoad = true;




While executing this code [ workbook.NameRanges["Table2"].RefersToRange = sheetQualityData.Range[1,1, sheetQualityData.LastRow, sheetQualityData.LastColumn]; ] .

I am getting object reference not set an instance of an object.

Please find the attached file for my template.

I am having the same problem. When i open the Excel file i am receiving an error.

This is my code:

Worksheet sheet2 = workbook.CreateEmptySheet();
sheet2.Name = "ACUMULADO";


//CellRange dataRange = sheet.Range[1, 1, sheet.LastRow, sheet.LastColumn];
int row = dt.Rows.Count;
int col = dt.Columns.Count;
string colName = GetExcelColumnName(col);
string range = String.Format("A1:" + "{0}" + row.ToString(), colName);
CellRange dataRange = sheet.Range[range];


PivotCache cache = workbook.PivotCaches.Add(dataRange);
PivotTable pt = sheet2.PivotTables.Add("Pivot Table", sheet.Range["A1"], cache);
pt.EnableDrilldown = true;//Habilitar Mostra detalles

var r1 = pt.PivotFields["EMPLEADO"];
r1.Axis = AxisTypes.Row;

var r2 = pt.PivotFields["DIA_LEIDO"];
r2.Axis = AxisTypes.Column;


pt.Options.RowHeaderCaption = "EMPLEADO";
pt.DataFields.Add(pt.PivotFields["TIPO_COMUNICACION"], "Cuenta de TIPO_COMUNICACION", SubtotalTypes.Count);


pt.CalculateData();//necessary
pt.Cache.IsRefreshOnLoad = true;

Hi David,

Thanks for your inquiry.
I simulated an Excel file and tested your scenario with the latest Spire.XLS Pack(Hotfix) Version:10.3.0, but didn't reproduce your issue. To help us further investigate it, please provide your input file and the value of "range" defined in your code.
You could upload here or send them to us(support@e-iceblue.com) via email. Thanks in advance.

Sincerely,
Rachel

Thank you, I work with the version FreeSpire.Office 4.3.1.might this be the issue?

If a five-row-range is generated then code works, however, if a 1000-row-range is created in stead it doesn´t works.

Regards,

David.

Hi David,

Thanks for your response.
Our commercial version contains more bug fixes and is more stable than the free version, we recommend you download the latest commercial version (Spire.XLS Pack(Hotfix) Version:10.3.0) to have a test.
If the issue still happens after trying, since it's difficult to locate the issue without your input file, please share it with us for further investigation. Thanks in advance.

Rachel
