New Post: Shared Workbook - notify users that changes occured

Hello,

consider multiple users having the same shared workbook open on their workstations.
I need some automated process to be applyed on this shared workbook.

When i use ClosedXML to update some cells, cells are updated, but users do not get notified by the change, and when someone does any action, the change operated by my ClosedXML action is erased.

The scenario i tested to get it work is that users have to close Excel and reopen the file to get the changes, which is not viable.

Is there a way or something to do to notify other open instances that ClosedXML has made a change ?

Thank you for your help,
Xavier.

Hi Team,

I have a work table in a worksheet that has items and being used by other worksheet, however the calculations are wrong since I am not able to extend range of the data table. Can somebody shed me some light using closedXML, as my only work around at the moment is use excel interop, Resize like this
var range = xlSheet.get_Range("A1", oMissing).get_Resize(xlListItem.ListRows.Count + 1, xlListItem.ListColumns.Count);
xlListItem.Resize(range);
var workbook = new clsXML.XLWorkbook(localPath);
var worksheet = workbook.Worksheet("Raw Metrics Data");
var worktable = worksheet.Table("MetricsLogging");

Console.WriteLine("Number of items in Excel at START: " + worktable.RowCount());
if (data.Count > 0)
{
       var lastrow = worktable.LastRow().Cell("F").Value; // Created Date
       DateTime lastUpdate = DateTime.Now.AddYears(-2); // Default Value, 2 years before last run
       if (lastrow.ToString().Length > 0)
              lastUpdate = (DateTime)lastrow;
       Console.WriteLine("Last Updated: " + lastUpdate.ToLongDateString());

       var metrics = from m in data where m.CreatedDate > lastUpdate orderby m.CreatedDate ascending select new { m.LogType, m.Category, m.Item, m.UDC, m.CreatedBy.LookupValue, m.CreatedDate, m.VisitingUrl.Url, region = m.CreatedBy.LookupValue.Substring(0, m.CreatedBy.LookupValue.IndexOf("\\")) };
        var tableWithData = worktable.Cell(worktable.RowCount() + 1, 1).InsertData(metrics.AsEnumerable()); // Insert the Data in Worksheet (not in worktable)


         workbook.SaveAs(localPath);

         Console.WriteLine("Number of items in Excel at END: " + worktable.RowCount());
}
Thanks in advance

Wendel

Did a little workaround, but not sure if this is the best practice... anyway.. :) hopefully somebody will make good use of this in the future. :)
var metrics = from m in data where m.CreatedDate > lastUpdate orderby m.CreatedDate ascending select new { m.LogType, m.Category, m.Item, m.UDC, m.CreatedBy.LookupValue, m.CreatedDate, m.VisitingUrl.Url, region = m.CreatedBy.LookupValue.Substring(0, m.CreatedBy.LookupValue.IndexOf("\\")) };
var nextRow = worktable.RowCount() + 1;
Console.WriteLine("Number of items to be added: " + metrics.Count());
if (metrics.Count() != 0)
{
         worktable.InsertRowsBelow(metrics.Count(), true);
         var tableWithData = worktable.Cell(nextRow, 1).InsertData(metrics.AsEnumerable());
         workbook.SaveAs(localPath);

New Post: Excel Formatting and worksheet initialization

[Coding Lang : C#]

Question :1
I'm using following code for getting "new line" in a cell and then adjusting rows height to properly display the cell content. Although the new line functionality is working properly but row height is not proper (Only the first line is visible).

IXLWorksheet ws = _Workbook.AddWorksheet("test");
ws.Cell(1,1).FormulaA1 = "=" + "\"New\"" + "&CHAR(10)&" + "\"Line\"";
ws.Style.Alignment.WrapText = true;
ws.Rows().AdjustToContents();

Question :2
As we can initialize a worksheet by a DataTable as follows:
var ws = _Workbook.Worksheets.Add(data_table, "sheet_name");
I need to initialize a worksheet from multiple data_tables (all having different structure) stacked side by side.

Initially, I was not able to get an export to Excel procedure working. I had virtually the same functionality working on a different page, so I was stumped for a while. The problem ended up being trying to execute code from a button located inside an asp:UpdatePanel. I took the button out of the UpdatePanel and it's all working just dandy now.

It appears to be a bug, I have the same issue. If you select rows using the IXLRows predicate function and want to delete them, it instead deletes all data in the worksheet. If you use clear however, it removes only the data you have selected and leaves the other rows untouched. Using that, you can iterate over the rows and delete the empty ones, more time costly, but I'm not aware of a better way to do it.

I am trying to set a text value to one of my columns.
Text value is 2015/06/03 15:15

Below is the code, that I use to set this column

excelWorkSheet.Cell(j + 1, k).SetDataType(XLCellValues.Text);
excelWorkSheet.Cell(j + 1, k)
.Style.NumberFormat.SetNumberFormatId(0);
excelWorkSheet.Cell(j + 1, k).Value = cellValue;

This is converting my string as a number.

How could I show this value as a text(Not as date time or a number)

Commented Unassigned: Syntax Error with VLookUp and/or Concatenate [9174]

Hi,

I've been using ClosedXML to read an Excel file (2010 version), and I get an error while reading the content of a cell containing this formula :

In Excel (french version) :
=RECHERCHEV(CONCATENER(D2;"-";F2;"-";H2;"-";I2;"-";J2;"-";K2);Buy!$A:$S;17;0)

In Visual Studio :
?oSht.Cell(idxRow, 12).FormulaA1
"VLOOKUP(CONCATENATE(D2,"-",F2,"-",H2,"-",I2,"-",J2,"-",K2),Buy!$A:$S,17,0)"

When I try to read the cell value, I get an error.

The error returned is this one : "Syntax Error" with no more comments.

The stack trace is :

à ClosedXML.Excel.CalcEngine.CalcEngine.Throw(String msg)
à ClosedXML.Excel.CalcEngine.CalcEngine.Throw()
à ClosedXML.Excel.CalcEngine.CalcEngine.Parse(String expression)
à ClosedXML.Excel.CalcEngine.ExpressionCache.get_Item(String expression)
à ClosedXML.Excel.CalcEngine.CalcEngine.Evaluate(String expression)
à ClosedXML.Excel.XLWorksheet.Evaluate(String expression)
à ClosedXML.Excel.XLCell.get_Value()

HResult : -2146233088

Is there a known problem with the VLOOKUP function, or CONCATENATE ?

Thanks in advance for your help

Comments: I think the problem is we don't currently support localized formulas. Are your formulas the french versions?

Commented Unassigned: Pivot Tables Values Problem [9088]

Based on the example [Pivot Tables](https://closedxml.codeplex.com/wikipage?title=Pivot%20Table%20example) , do the following steps to reproduce the problem

Excellent example . It works perfect, but if you add more than one value will have a problem . Here I leave an example to reproduce the problem . Suppose Pastry class has one more property called "Amount" int

Step 1. Add two values

```
// The values ​​in our table will come from the " NumberOfOrders " field
// The default setting is a full calculation of each row / column
pt.Values.Add ("NumberOfOrders");

// Another value ( THIS IS THE ONE THAT CAUSE THE PROBLEM )
pt.Values.Add ("Amount" ) ;

```


Step 2. Save the excel file

Step 3. Open the excel file , and throw the following message

We found a problem with Content ' Patry.xlsx ' . Do you want to try to recover as much content as possible ? If trusts origin of this book , please click yes .

Click yes, and I'll get the following message :

Removed Feature: PivotTable report from / xl / PivotTables / pivotTable.xml part ( PivotTable view)
Records removed : book Properties / xl / workbook.xml part ( Book)


Step 4. Final result , the pivot table is not generated

aTTACH project C# for reproduce problem.

Please expect your help to solve this problem .. thank you very much
Comments: I have started to do research into this issue, but I am not 100% sure the best way to fix this. The problem is because in Excel as soon as you add more then 1 field to values, Excel generates an automatic "Values Label" We need to generate this field, and update the Pivot Cache. The reason, I am hesitant to do anything at the moment, is because That Field can be moved between the Rows and Columns Categories. I am not super familiar with Excel Pivot Tables, and do not know how this would affect the API. Hopefully my research will help another developer who is more familiar with this part. It should be noted that the values field has a field index value < 0 in my case I observed it was -2. This is how you can tell the values field apart from an regular Pivot Field. See attached screenshot.

Hi.
Anyone has issues accessing Pivot tables?
.WorkSheet.PivotTables.Count() returns 0 ..

... yet, when I access the xlsx via OpenXML, i can see the Pivot...

using ClosedXML ver 0.69.1.0 on Framework 4.0 ... please advise, thanks....
Comments: Can you provide a reproduction case. I can't reproduce this. How are you getting the worksheet? Do you have a handle on correct worksheet. Note: The worksheet position is 1 based. So var x = workbook.Worksheets.Worksheet(2).PivotTables.Count(); will actually return the SECOND worksheet in the workbook. Make sure you getting a handle on the correct worksheet.

New Post: XLWorkbook.Save causes spreadsheet to lose data

I have written some code using ClosedXML that should open a spreadsheet, change the range of a table, and save it, and when I debug the methods everything looks great. But when I open the spreadsheet after saving, the contents of several columns have vanished.

Here are two versions of my method I've written:
    private void UpdateTableRange(string filePath)
    {
        var spreadsheet = new XLWorkbook(filePath);
        var worksheet = spreadsheet.Worksheets.FirstOrDefault(s => s.Name == "Usage");

        var range = worksheet.Range(worksheet.FirstCell(), worksheet.LastCellUsed());
        worksheet.Tables.Remove("Usage");
        var table = range.AsTable("Usage");
        worksheet.Tables.Add(table);

        spreadsheet.Save();
    }

    private byte[] UpdateTableRange(byte[] file)
    {
        var stream = new MemoryStream();
        stream.Write(file, 0, file.Length);
        var spreadsheet = new XLWorkbook(stream);
        var worksheet = spreadsheet.Worksheets.FirstOrDefault(s => s.Name == "Usage");

        var range = worksheet.Range(worksheet.FirstCell(), worksheet.LastCellUsed());
        worksheet.Tables.Remove("Usage");
        var table = range.AsTable("Usage");
        worksheet.Tables.Add(table);

        spreadsheet.Save();

        return stream.ToArray();
    }
I thought that perhaps I was messing up the data by removing the table and adding a new one, but if I do nothing more than open the workbook and save it, having first made no changes, whatosever, I still lose the contents of some of the columns.

Can anybody think of a reason this might be happening? Is there some way data might be defined in a worksheet such that opening the spreadsheet in ClosedXML and saving it, without making changes, could nevertheless cause the contents of some columns to disappear? If it helps, the columns whose content vanishes are all non-numeric: dates, strings, etc.

It looks like immediately after opening the spreadsheet using new XLWorkbook(...), the data in the original hasn't been loaded into memory:

(new System.Linq.SystemCore_EnumerableDebugView<ClosedXML.Excel.IXLWorksheet>(((ClosedXML.Excel.XLWorksheets)(spreadsheet.Worksheets)))).Items[10].Cell(2,1).Value

The above code returns an empty string, even though the original worksheet has a user's name in that cell. And so when I save the XLWorkbook, naturally the empty value gets saved resulting in the data loss about which I'm complaining.

Interestingly, ...Cell(1,1).Value returns "UserName" which is correct--it's the value of the cell serving as the column header.
