Commented Unassigned: Changing a Column Header's text [9383]

September 21, 2016, 11:17 pm
$
0
0
I am trying to change the text of cells in the first row of the spreadsheet, essentially the column header.

This example is just changing the first cell in row 1.

```
Dim l_sValue As String
l_sValue = "test"
wb.Worksheets(0).Cell(1, 1).DataType = XLCellValues.Text
wb.Worksheets(0).Cell(1, 1).Value = l_sValue
```

However, when I do this the spreadsheet needs to be repaired when I open it. If I change any cell other than a cell in row 1 I have no issues.

I need to modify the column headers so they have a better meaning and can't do this in the DataTable that I am importing from.
Comments: Is this issue fixed in ClosedXML 0.76.0 version ?

I am using this code to set the header on a document that already contains headers(first page and odd even) and it does not work.

pageSetup.Header.Center.AddText("first", XLHFOccurrence.FirstPage);
pageSetup.Header.Center.AddText("odd", XLHFOccurrence.OddPages);
pageSetup.Header.Center.AddText("even", XLHFOccurrence.EvenPages);

if i delete the headers, it does work.

using pageSetup.Header.Center.Clear(); does not work either.

Closed Unassigned: Table Theme [9499]

Attached is an excel file with a custom Table Style. The loading of the table theme borks because enum.parse can't find a value. Recommend changing the theme to a string and using enum.tryparse. Have a helper that lets you get standard excel themes but still allows custom theme names.

Greetings,

I'm trying to write a datetime to a cell using ClosedXML. I set the IXLCell DataType to be XLCellValues.DateTime, and the value to be a new DateTime. I also set the number format id to 14 (mm/dd/yyyy)

When I look at the excel sheet, the date displayed is always one day larger than anticipated. When I read the cell value using ClosedXML (in a unit test), the value read from the file matches the value I wrote, but the actual excel sheet does not show the correct value.

Is this a bug in ClosedXML or am I missing something?

Thanks!

Comments: I'm using the latest codebase on the `develop` branch on Github and I can't replicate this problem. Here is my code; ```c# public void Create(String filePath) { var workbook = new XLWorkbook(); var worksheet = workbook.Worksheets.Add("Sample Sheet"); worksheet.Cell("A1").Value = "Hello World!"; var cell = worksheet.Cell("A2"); cell.Value = new DateTime(2016, 1, 1); cell.DataType = XLCellValues.DateTime; cell.Style.NumberFormat.NumberFormatId = 14; workbook.SaveAs(filePath); } ``` If I open the generated Excel file, I see "2016-01-01" in the cell. Can you please post a simple example to reproduce your problem?

I am creating an excel file in excess of 40MB using the .net 4.5.1 framework with ClosedXML for .Net Framework 4.0. I save and reopen the file to append every 10000 rows to conserve memory. This error occurs when Save is executed.

Is there a workaround for the following error ? Does this error occur in the previous 3.5 DLL?

New Post: Cannot convert theme color to color

Hi everyone,
I'm new to CLosedXML and so far it seems really interesting. However I have a problem that I cannot solve... Basically, what I'm doing, is opening an Excel file (with some layout and colors already applied) and fill it with data. In my code, I only enter data and formulas. I don't apply any cell formatting except from centering some data. However, when I save the workbook, I get the error "Cannot convert theme color to Color". I suspect the problems come from the file that I open or a bug in ClosedXML because if I open the file and immediately save it, I still have the same error on save. Any ideas about what could be the problem or if anything should be changed in the source file (through Excel)? By the way, I have no problem opening the source file in Excel...

I'm using VB.NET in Visual Studio 2015 if it helps.

Thanks

Jean

Commented Unassigned: Error doing data validation from another sheet [9498]

November 11, 2016, 2:00 am

When using closedxml to add data validation to a file, all validations are written in the <x:dataValidations> element. However, this is not how excel saves data validation from other sheets.

Here's how closed xml saves it:

```
<x:dataValidations count="3">
<x:dataValidation type="list" errorStyle="warning" operator="between" allowBlank="0" showDropDown="0" showInputMessage="1" showErrorMessage="1" errorTitle="" error="" promptTitle="" prompt="" sqref="B6:B6">
<x:formula1>"Foo,Bar,FooBar"</x:formula1>
<x:formula2></x:formula2>
</x:dataValidation>
<x:dataValidation type="list" errorStyle="warning" operator="between" allowBlank="0" showDropDown="0" showInputMessage="1" showErrorMessage="1" errorTitle="" error="" promptTitle="" prompt="" sqref="C6:C6">
<x:formula1>'HiddenDataValSheet'!$A$1:$A$1000</x:formula1>
<x:formula2></x:formula2>
</x:dataValidation>
<x:dataValidation type="list" errorStyle="warning" operator="between" allowBlank="0" showDropDown="0" showInputMessage="1" showErrorMessage="1" errorTitle="" error="" promptTitle="" prompt="" sqref="D6:D6">
<x:formula1>'HiddenDataValSheet'!$B$1:$B$1000</x:formula1>
<x:formula2></x:formula2>
</x:dataValidation>
</x:dataValidations>

```

And here's how excel saves it:

```
<extLst>
<ext uri="{CCE6A557-97BC-4b89-ADB6-D9C93CAAB3DF}" xmlns:x14="http://schemas.microsoft.com/office/spreadsheetml/2009/9/main">
<x14:dataValidations count="2" xmlns:xm="http://schemas.microsoft.com/office/excel/2006/main">
<x14:dataValidation type="list" errorStyle="warning" showInputMessage="1" showErrorMessage="1">
<x14:formula1>
<xm:f>HiddenDataValSheet!$A$1:$A$1000</xm:f>
</x14:formula1>
<xm:sqref>C6</xm:sqref>
</x14:dataValidation>
<x14:dataValidation type="list" errorStyle="warning" showInputMessage="1" showErrorMessage="1">
<x14:formula1>
<xm:f>HiddenDataValSheet!$B$1:$B$1000</xm:f>
</x14:formula1>
<xm:sqref>D6</xm:sqref>
</x14:dataValidation>
</x14:dataValidations>
</ext>

```

I'll need to modify the closed xml code to be able to read the data validations from the <extLst> element and treat them like normal data validations.
Comments: Do you perhaps have a test case to illustrate the problem and hence this fix?
