Created Unassigned: Date Axis [14952]

I believe there currently is only support for valAx type. It'd be great to have support for dateAx so access to properties such as basetimeunit are available.

<c:dateAx>
<c:axId val="244914048"/>
<c:scaling>
<c:orientation val="minMax"/>
</c:scaling>
<c:axPos val="b"/>
<c:numFmt formatCode="mm/dd/yyyy" sourceLinked="0"/>
<c:tickLblPos val="nextTo"/>
<c:crossAx val="244915584"/>
<c:crosses val="autoZero"/>
<c:auto val="1"/>
<c:lblOffset val="100"/>
<c:baseTimeUnit val="months"/>
</c:dateAx>

Comments: I have the same issue. it seems like some kind of black magic voodoo. Some clarification/explanation would be great. I used a workaround: Set the column/row width in excel -> save -> change the extension of the file to .zip -> open it -> navigate to the worksheet/sheet1.xml -> open -> copy/paste the values from there hope this helps Mathias

Comments: I'm running into the exact same problem. I can make changes to the ExcelWorksheet that register (if I look at the local variable while the program is running), but the changes are not saved to the spreadsheet.

Commented Issue: Indexing a cell in an ExcelRange modifies the ExcelRange [14827]

I create a cell range from an ExcelWorkSheet object, then reference a cell in that range.

```
var range = sheet.Cells[1, 1, 5, 5];

var a1 = range.Address;
var c = range['B2'];
var a2 = range.Address;

Assert.AreEqual(a1, a2); // THIS FAILS
```

However, while a1 is equal to "A1:E5", a2 is equal to "B2". This seems wrong. How am I supposed to go about accessing cells in a range without the index operator?

VS2012, Windows 7, .NET Framework 4.5
Comments: Workaround: var c = range.Worksheet.Cells['B2'];

Commented Issue: System.InvalidOperationException saving document with cloned sheet containing images [14776]

EPPlus is working fantastically for my project, except that I get an exception when saving a document that contains a cloned sheet with images.

If I leave the 'template' sheet in the document then it saves fine.

If I delete the template I get the following exception when saving:

[System.InvalidOperationException] = {"Specified part does not exist in the package."}
at OfficeOpenXml.ExcelPackage.Save()
at OfficeOpenXml.ExcelPackage.SaveAs(FileInfo file)


I have made the simplest template that shows the issue (attached).

Example code is:

public void DemonstrateError()
{
var templateFile = new FileInfo(Environment.CurrentDirectory + @"\Templates\Template.xlsx");
var outputDirectoryInfo = Directory.CreateDirectory(Environment.CurrentDirectory + @"\Reports\" + DateTime.UtcNow.ToFileTimeUtc());
var outputFile = new FileInfo(outputDirectoryInfo.FullName + @"\Report.xlsx");

using (var package = new ExcelPackage(templateFile))
{
//Copy the template sheet to a new one.
var newSheet = package.Workbook.Worksheets.Copy("Template", String.Format("Site {0}", 1));

/* Normally lots of processing goes here */

//We no longer need the template sheet.
package.Workbook.Worksheets.Delete("Template");

//Save the completed document (will generate an exception)
package.SaveAs(outputFile);
}
}
Comments: Calling the setter of the Image property was a workaround for me. ``` foreach (ExcelDrawing ed in nws.Drawings) { if (ed is ExcelPicture) { Image img = (ed as ExcelPicture).Image; (ed as ExcelPicture).Image = img; } } ```

Commented Issue: Using EPPlus to create Excel spreasheets [14751]

Hello, working in asp.net C#...initially i fell into the problem with the Excel.Interop not being able to open excel on Host pcìs due to the Microsoft limitations.

So i decided to try EPPlus to get round this problem. Very simple...followed the EPPlus samples and tried to create an excel file (.xlsx) ad open it at the same time...this is part of the code i got from the sample...

xlPackage.SaveAs(Response.OutputStream);
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment; filename=Sample1.xlsx");

no errors, but cannot find any Sample1.xlsx file anywhere...

I would just want to create the excel file from a template and then show this last...obviously this has to work on host pc's.
Please help, i'm stuck!
Thanks
Stefano
Comments: It can be solved by changing the code in to this... ``` Response.Clear(); //Response.Flush(); Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("content-disposition", "attachment; filename=ExcelDemo.xlsx"); Response.BinaryWrite(pck.GetAsByteArray()); Response.End(); ```

Hi,

I have to generate large (250.000 rows and more) Excel files. It works well, but when I Dispose() The ExcelPackage at the end the memory isn't released. I checked my code and I can't find a "stray" reference or somthing alse that would stop the GC to work.. A call to GC.Collect() doesn't free the memory either .. Does anybody else have this issue? Is there something I am forgetting?

Thanks for your help in advance!!

Created Unassigned: Chart Axis Crosses and CrossBetween bugs [14957]

March 12, 2014, 4:28 am

Creating a chart with x-axis using Cross or CrossBetween options is inserting invalid values in the xml, and Excel can't parse the chart when opening the file.

Example:
<c:crossBetween val="etweenetween" />
or
<c:crossBetween val="idcatidCat" />

(Proper values are "between" and "midCat".)

This is caused by a simple mistake in file Drawing/Chart/ExcelChartAxis.cs on lines 251 and 269.

Currently these lines are:
v = v.Substring(1).ToLower() + v.Substring(1, v.Length - 1);
but they should be:
v = v.Substring(0,1).ToLower() + v.Substring(1, v.Length - 1);

(Notice only difference is v.Substring(__0__,1)

I traced down the issue and found that the GetWorkSheetXml method of the ExcelWorksheet class returns invalid XML. This is in Line 682 of the ExcelWorksshet.cs in the current version:

xml += "<sheetData/>" + s.Substring(endMatch.Index + endMatch.Length, s.Length - (endMatch.Index + endMatch.Length));

Before this line the value of the "xml" variable is a valid XML, but after this it contains duplicate XML declarations. See the attached screenshots that were created in the debugger before and after executing this line.

Thank your for creating and providing this library, and thanks in advance for fixing this issue.
Comments: Hi All, I'm also getting below error while reading excel generated by third party source.. Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it. Line 1, position 130.

Commented Issue: Inserting Row doesn't update Addresses of NamedRanges [13628]

When you insert a row in Excel, named ranges that are in rows 'below' the inserted row get shifted appropriately. This doesn't seem to be the behavior in EPPlus. Shouldn't it be?

In the meantime, I'm going to try to manage the ranges programmatically.
Comments: Jees! Why is this low priority and been sitting around for two or three years. Note: This solution doesn't work the second time if you add another range of rows because 'Address' no longer refers to the full address. I fixed it for my case by changing this part of the code back to 'FullAddress' var ng = (from item in workBook.Names where item.Worksheet.Name.ToUpper() == workSheet.Name.ToUpper() && item.FullAddress.ToUpper().Contains(workSheet.Name.ToUpper()) && item.Start.Row >= rowStart select item).ToList(); I'm not sure of any new edge cases, but worked for me

When I create spreadsheet with many worksheets via my site using EPPlus, I get the following error:

Excel found unreadable content in ViewData2023_all.xlsx Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes.

Then I get the Repairs popup, and when I open up the log file I see:

<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"><logFileName>error094560_01.xml</logFileName><summary>Errors were detected in file 'C:\Users\xxx\Downloads\ViewData2023_all.xlsx'</summary>-<repairedRecords summary="Following is a list of repairs:"><repairedRecord>Repaired Records: Worksheet properties from /xl/workbook.xml part (Workbook)</repairedRecord></repairedRecords></recoveryLog>

Here is a sample of the code:
using (ExcelPackage package = new ExcelPackage())
{
foreach (Install install in Installs)
{
DataWorksheet dwtest = BuildDataWorksheet(site1ID_int, install.InstallID.ToString(), StartDate, EndDate);
if (dwtest.DataRecords.Count > 0)
{

string worksheetName = dwtest.Name;

ExcelWorksheet ws = package.Workbook.Worksheets.Add(worksheetName);

int chssz = dwtest.ColumnHeaders.Count;

int worksheet_col = 0;
int worksheet_row = 0;
for (int hdr_col = 1; hdr_col <= dwtest.ColumnHeaders.Count; hdr_col++)
{
worksheet_col = hdr_col - 1;
ws.Cells[1, hdr_col].Value = dwtest.ColumnHeaders[worksheet_col];
}

for (int cell_row = 2; cell_row <= (dwtest.DataRecords.Count + 1); cell_row++)
{
worksheet_row = cell_row - 2;
for (int cell_column = 1; cell_column <= dwtest.DataRecords[worksheet_row].CellValues.Count; cell_column++)
{
worksheet_col = cell_column - 1;
ws.Cells[cell_row, cell_column].Value = dwtest.DataRecords[worksheet_row].CellValues[worksheet_col];
}
}
} // end of if DataWorksheet has DataRecords
} // end of foreach

var stream = new MemoryStream();
package.SaveAs(stream);

string fileName = "ViewData.xlsx";
string contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

stream.Position = 0;
return File(stream, contentType, fileName);
}
}

Note:
- when I open in Excel and resave the spreadsheet is fine
- when I create a spreadsheet with one worksheet, the spreadsheet is fine

Thanks!
Comments: I am seeing this exact same error. Any thoughts on when a fix might be available for this issue?
