Created Unassigned: Auto Height for Rows [9432]

Great library but one trouble here - if you like to copy and modify rows often you touch row's height property . Then library sets height as CustomHeight.
So it seems the most simple way looks like to set CustomHeight off

I suppose to to set height as automatically with special function like int other openexcel libraries
SetAutoHeight()

Name actually does not matter

Could you consider ability to add Function to reset Height of Row to allow Excel automatically set it?

Here code working for me:
IXLRows.cs
namespace ClosedXML.Excel
{
public interface IXLRows: IEnumerable<IXLRow>, IDisposable
{
...
/// <summary>
/// Set the height of all rows as auto. Excel should set height automatically then.
/// </summary>
IXLRows SetAutoHeight();
...



XLRows.cs
namespace ClosedXML.Excel
{
using System.Collections;

internal class XLRows : IXLRows, IXLStylized
{
...
public IXLRows SetAutoHeight()
{
_rows.ForEach(r => r.SetAutoHeight());
return this;
}
...


XLRow.cs
namespace ClosedXML.Excel
{
internal class XLRow : XLRangeBase, IXLRow
{
...

internal object SetAutoHeight()
{
int row = RowNumber();
var thisRow = Worksheet.Internals.RowsCollection[row];
//Ensure for now that row height will be auto
thisRow.HeightChanged = false;
HeightChanged = false;
return this;
}

}
}

Is there any way to set the row height for each row so it fits all the text from a certain column (with word wrap enabled)?

A customer-provided Excel document contained a Formula referencing a second file using a formula like

```

```

which results in a `System.Exception`: Identifier expected.

```

As documented in issues like https://closedxml.codeplex.com/workitem/9402 there seems to be an issue with the formula parser if single quotes are involved. It looks like there is currently no (easy?) way to check for formula validity before accessing a cell value. I don't suspect that cross file references are supported at all.
I was hoping for a way to validate a formula or a defined set of distinct Exception types (e.g. like UnsupportedFormulaException, SyntaxException) to be able to better distinguish what is going on.

New Post: Cell metadata?

May 6, 2015, 7:21 am

I'm building an app that reads a data dictionary file and uses ClosedXML to build a fairly complex Excel workbook based on its contents. I need to store some meta-information at the cell level in a number of locations so another tool can later consume the excel file and relate certain cells back to the data dictionary.

I know that OpenXML offers cell level metadata and ExtensionList objects (though I haven't found many concrete examples of how they're used); does ClosedXML offer any kind of metadata mechanism that doesn't involve comments or hidden columns?

Failing that, is there any way to map a ClosedXML cell object directly to its OpenXML equivalent? Otherwise I assume if I have to go the OpenXML-for-metadata route I'll have to save & close the file from ClosedXML and reopen it in OpenXML for a second pass through to apply the metadata.

Created Unassigned: Extra empty cells added when inserting comment [9434]

May 7, 2015, 5:26 am
$

When adding a comment to a cell extra empty cells are added in the excel sheet which are not touched by the code.

With the following code:
```
var workbook = new XLWorkbook();
var worksheet = workbook.Worksheets.Add("Test");

var cell = worksheet.Cell(1, 1);
cell.Comment.AddText("test comment");

using (var ms = File.Open("Test.xlsx", FileMode.CreateNew))
{
workbook.SaveAs(ms);
}
```

You can find these cells in the Excel application by using the 'Find & Select' option, select 'Go To Special' and select 'Blanks' and press OK (see screenshot).

I think it is strange because these cells are not actually touched, but they are updated when writing the excel data. Normally it is not a problem, but our client complaints about it because they are using it to import data with a script which cannot handle the extra blanks in the sheet.

The problem lies in the surrounding cells which are requested from the XLCellsCollection object. When the comments are added the GenerateShape method is called which calls the GetAnchor method. This method requests the surrounding cells to determine the anchor which updates the the MaxColumnUsed and MaxRowUsed properties of the collection. These properties are updated, but are not actually used.

I want to fix this problem, but I do not know what this anchor means or does. When I remove the anchor from the ClientData on the Shape which is generated it results in the exact same output and the comments are displayed ok.

Can someone help me fixing this problem?

Thnx, Erwin

New Post: Save choking on formula in GetA1Column

I have a spreadsheet that was working as a template (using ClosedXML to add data to the template). After opening the template with Excel 2010 and saving it (no other changes), it began to fail on Save() in ClosedXML.

After downloading the ClosedXML source, and running it in debug, the failure is in the XLCell.cs in the "GetA1Column" method when it is passed a columnPart = "C-".

You can duplicate this with a very simple spreadsheet. Enter the formula "=IF(ISERROR(B1-(B2)),0,B1-(B2))" in cell B3. Drag the formula across to E3 (copies the formula into C3, D3, and E3). Save the spreadsheet as "C:\Test.xslx".

Create a Console program (I used the ClosedXML_Sandbox) that opens and tries to save the Text.xlsx spreadsheet, it should fail in the GetA1Column method (on the line "columnToReturn = XLHelper.GetColumnLetterFromNumber(Address.ColumnNumber + Int32.Parse(columnPart.Substring(mIndex)) + columnsToShift);" with the error

Dear colleagues !

Do I correctly understand that ClosedXML does not work with charts ?
That is, ClosedXML has not methods to add/delete chart, to manipulate chart's data, etc.
Or I have missed something ?

New Post: Inserting a formula in a TotalsRow

May 11, 2015, 1:56 am

Hi,

I have a simple Excel sales report, with 4 columns: customer, turnover, margin, and margin percentage.
I have added a TotalsRow (awesome functionality by the way), with sums of the turnover and margin columns, and the average of the margin percentage. Sounds straightforward, but this is not correct, because obviously the margin percentages are not weighted by the turnover and margin in the total average.

For example:
Customer Turnover Margin Margin %
Customer A 10,000 5,000 50 %
Customer B 100,000 25,000 25 %
Total: 110,000 30,000 37.5 %

The total margin % is actually 27.3 % (30K / 110K), not 37.5 % (75 / 2)

So in my code, I add the totalsRow, and then I tried to simply replace the content of the total margin percentage cell with a formula (Total margin / total turnover).

The problem is, this always results in Excel claiming that there is unreadable content, after which it empties the cell, and also the cell to the left. So I end up with:
Customer Turnover Margin Margin %
Customer A 10,000 5,000 50 %
Customer B 100,000 25,000 25 %
Total: 110,000

Can I, or how should I write formulas like this to cells in the TotalsRow ?

Regards,
Johan

Commented Unassigned: Unreadable content in Excel file after deleting sheets [9428]

May 12, 2015, 6:56 am

I have a template .xlsx file which I open with ClosedXML, populate with necessary info, and depending on the user options, delete some irrelevant sheets (mostly the empty ones). Then I save the file, but when the user tries to open the file, Excel complains about unreadable content (a common error, I know).

My sheets contain NamedRanges and Tables, and there are also some pivot tables. I try to delete these all explicitly before deleting the actual sheet, but I think some reference somewhere still remains.

I attach a simplified version of the empty template file, some code that shows how I delete the sheets, and the resultant file that has the 'unreadable content'.

We're on Excel 2010, Windows 7 32b, ClosedXML 0.76.0.0

Please advise.

``` C#
private void DeleteIrrelevantSheet(XLWorkbook wb)
{
new string[] {
"YieldCurvePivot",
"GeneratedYieldCurveEntries"
}.ForEach(s => DeleteSheetAndTable(wb, s));
}

private void DeleteSheetAndTable(XLWorkbook wb, string sheetName)
{
var sheet = wb.Worksheet(sheetName);

//Delete named ranges on workbook level pointing to sheet
string[] namedRangesToDelete = wb.NamedRanges.Where(nr => nr.RefersTo.Contains(sheetName)).Select(nr => nr.Name).ToArray();
foreach (var nr in namedRangesToDelete)
{
wb.NamedRanges.Delete(nr);
}

//Delete named ranges on sheet level pointing to sheet
foreach (var sheet2 in wb.Worksheets)
{
namedRangesToDelete = sheet2.NamedRanges.Where(nr => nr.RefersTo.Contains(sheetName)).Select(nr => nr.Name).ToArray();
foreach (var nr in namedRangesToDelete)
{
sheet2.NamedRanges.Delete(nr);
}
}

//Delete tables
var tablesToDelete = sheet.Tables.Select(t => t.Name).ToArray();
foreach (var table in tablesToDelete)
{
sheet.Tables.Remove(table);
}

//Delete pivot tables
sheet.PivotTables.DeleteAll();
sheet.Delete();
}

```
Comments: If someone can help me pinpoint what is going wrong in the XML files in the .xlsx file, I can try to write a patch. But I don't know the schema well enough to find the problem.

Created Unassigned: Traverse merged cells? [9436]

May 17, 2015, 5:04 am

Currently if we use cell.CellRight(), we can traverse the cells as if they were unmerged. This is fine. However, this imposes strict requirements on file structure of my users. If they choose to merge multiple cells then I have to change code so I am jumping over cells to account for merging. ClosedXML provides a way to know if a cell is merged (IsMerged()), however there is no way to find out which merged range current cell belongs to.

I think this would a nice feature to have. Either this, or traverse cells in a way so that it automatically skips remaining cells in merged range.
