hi,
is there any way to tell Spire.XLS to use the classic layout for pivot table?
haw i can say Spire.XLS to adjast column width in pivot table?
what is the command to compress / expand the fields in the pivot table?

I can add a calculated column with the difference between two columns in pivot table?
i try << pt.PivotTables(0).CalculatedFields.Add("Delta %", "Ricavi-Costi") >>
but the function returns the error << Riferimento a un oggetto non impostato su un'istanza di oggetto. >>
Why?

There is a manual for Spire.XLS with all the functions and usage?

thanks in advance

Sorry that at present Spire.Xls doesn't support the feature to add the CalculatedFields.

but then what is the method "sheetPivot.PivotTables (0) .CalculatedFields.Add"

I saw that if there is a calculated field I can change the formula. I can delete a calculated field already?

plan to implement the method to add calculated fields?

for classic layout I meant if it was possible to automatically activate the option " Layout classico tabella pivot (consente il trascinamento di campi nella griglia" as shown in the attached file

another question? can i update source data of an existing pivot table? how?

best regards

Hello,

Although there is the method "sheetPivot.PivotTables (0) .CalculatedFields.Add", at present Spire.Xls doesn't support to add or delete the calculated field, and you can change its formula with the following method.
Code: Select all
pt.CalculatedFields["Field1"].Formula = "1";

In current version it doesn't support the option" Layout classico tabella pivot (consente il trascinamento di campi nella griglia", which will be supported in next version.
Regarding the late issue, do you want to change the source data of an existing pivot table? or else?

Thanks,
Gary

Hello,

Thanks for the information, here are some codes for your reference.
Code: Select all
Workbook workbook = new Workbook();
workbook.LoadFromFile("pt.xlsx");
Worksheet ptSheet = workbook.Worksheets["Pivot Table"];
Worksheet dataSheet = workbook.Worksheets[0];
//replace the source data of name range
workbook.NameRanges["DataSource"].RefersToRange = dataSheet.Range["A1:C218"];
XlsPivotTable pt = ptSheet.PivotTables[0] as XlsPivotTable;
//refresh
pt.Cache.IsRefreshOnLoad=true;
workbook.SaveToFile("Ptresult.xlsx", ExcelVersion.Version2010);

Hello Gary,
I tried your code and updating the NamedRange is correct.
also refresh data is ok.

I found another problem (or bad?) in my excel file template I added a CalculatedField, and I set it to be displayed as "PercentageOfParent" but after saving the new file the option "ShodataAs" was restored to "Normal" and "BASEITEM" to "0".

if I try to change options in code i retrieve an error when i save as show in figure.

There is a fix for this?

Best Regard


My Code:

'***************************************************************
'** LOAD EXIST XLS FILE AND CHANGE DATASOURCE FOR PIVOT TABLE **
'***************************************************************
workbook.LoadFromFile(NomeFileTemplate)
Dim sheetDati As Worksheet = workbook.Worksheets(1)
Dim sheetPivot As Worksheet = workbook.Worksheets(0)
sheetDati.Clear()
sheetDati.InsertDataTable(ExcelDt, True, 1, 1)
workbook.NameRanges("DataSource").RefersToRange = sheetDati.Range(1, 1, sheetDati.LastRow, sheetDati.LastColumn)
Dim pt As XlsPivotTable = sheetPivot.PivotTables("Pivot Table")
pt.DataFields(6).BaseItem = 2
pt.DataFields(6).ShowDataAs = PivotFieldFormatType.PercentageOfParent
sheetPivot.PageSetup.Orientation = PageOrientationType.Landscape
sheetPivot.PageSetup.FitToPagesWide = 1
sheetPivot.PageSetup.FitToPagesTall = 1000
workbook.SaveToFile(NomeFile, ExcelVersion.Version2007)
System.Diagnostics.Process.Start(NomeFile)
'***************************************************************
'** LOAD EXIST XLS FILE AND CHANGE DATASOURCE FOR PIVOT TABLE **
'***************************************************************

Hello,

Thanks for your response. The error you retrieved is caused by the "PercentageOfParent" option, there is bug in it. I have transferred it to our Dev team, once there are any progress, we will notify you immediately. Sorry for inconvenience.
Thanks,
Gary

Hello,

Glad to notify you that now it is supported that setting the classic layout for pivot table, you can download the newest hotfix(Spire.XLS Pack Hotfix Version:7.6.43) and try the following code.
Code: Select all
XlsPivotTable.Options.ShowGridDropZone = true;

Gary

Hi,

I am using below code for refresh the pivotal table with update datasource.

Workbook workbook = new Workbook();
workbook.LoadFromFile("pt.xlsx");
Worksheet ptSheet = workbook.Worksheets["Pivot Table"];
Worksheet dataSheet = workbook.Worksheets[0];
//replace the source data of name range
workbook.NameRanges["DataSource"].RefersToRange = dataSheet.Range["A1:C218"];
XlsPivotTable pt = ptSheet.PivotTables[0] as XlsPivotTable;
//refresh
pt.Cache.IsRefreshOnLoad=true;
workbook.SaveToFile("Ptresult.xlsx", ExcelVersion.Version2010);

But I am getting issues while executing below this code

//replace the source data of name range
workbook.NameRanges["DataSource"].RefersToRange = dataSheet.Range["A1:C218"];

Error- Object reference not set to an instance of an object

Please help me how can I resolve this issues.

Thanks
