New Post: Conditional format color for Less Than

Tridus — Wed, 22 May 2013 18:48:02 GMT

Nevermind, figured it out. :) You can set condition.Style.Font.Color.Color to a System.Drawing.Color object.

Not sure how I missed that, sorry for the silly question. :)

New Post: Conditional format color for Less Than

Tridus — Wed, 22 May 2013 17:14:01 GMT

Hi. I'm trying to set a color for a less than conditional format. Here's the format code:

var condition = sheet.ConditionalFormatting.AddLessThan(addr);
condition.Formula = "50";

By default, this doesn't set the conditional format with any color, so you can't see it. I know the condition itself is working, since I can add something like italics and that shows up.

The issue is that unlike the other conditions, there is no condition.Color for Less Than that I can find. Instead you have to set Style.Font.Color, and that doesn't take a Color object to set it. It takes some kind of ExcelDxf object that I'm really not clear on how to use.

Any advice on how to do this? Also, why is this one inconsistent from the ones like Two Color Scale, which just takes a Color object?

Thanks.

BVictor — Tue, 21 May 2013 12:20:06 GMT

I have the same issue. The unlock works in Excel 2010, but not within the Framework.

Besides, after the exception "Invalid Password" is thrown, the file remains stuck inside the process. (not sure if the framework has something to do about this.)

Did you find a solution?

New Post: Specified NumberFormat defaulting to Date

tmaly — Mon, 20 May 2013 17:06:35 GMT

I am having a difficult time setting the Number Format for cells in a worksheet that has been loaded from a template.

If I try to set the Numberformat property for a cell to "#,##0.00;Red" or "#,##0.00_);(#,##0.00)" or "#,##0.00;(#,##0.00)" the result winds up formatted as a date (mm/dd/yyyy).

The method I am using to set the cell format/value in all cases is:

using (var cell = WorkSheet.Cells[rowIdx, columnIdx])
{
       cell.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
       cell.Style.Font.Size = 8;
       cell.Style.Numberformat.Format = "#,##0.00;[Red](#,##0.00)";
       cell.Value = <decimal/string value>;  
}

Has anyone else encountered this issue? Is there a best practice with regard to cell format setting?

New Post: Expand Excel Table

NickWard — Fri, 17 May 2013 13:10:06 GMT

I would like populate an excel table within a template.

The table will be linked to charts and pivots that exist within the template prior to population by EP plus.

When I try to expand the excel table using insert row method the new rows are inserted into the spread sheet but the table row count remains the same (3 rows)

How can I expand an existing excel table to the datatable record count?

Thanks

Commented Unassigned: Invalid URL Exception [14858]

abdaizs — Thu, 16 May 2013 16:00:59 GMT

Hi!

I have a problem, if I try to open an XLSX file with EPPlus. The File was created with Microsoft Office 2010.

My code is:

```
foreach (string fajl in fajlok)
{
FileInfo fn = new FileInfo(@fajl);
string indicated_user = fn.Name.Split('_')[0];
ExcelPackage ep = new ExcelPackage(fn);

Constans.GLOBALLOG.LogWrite(ep.Workbook.Worksheets.Count().ToString());
if (ep.Workbook.Worksheets.Count() == 3)
{
.....
```

The Exception occurs at ep.Workbook.Worksheets.Count().
I read, that this problem has already fixed, however, it happened...

Is any fix for this problem?
I use the latest DLL version: EPPlus 3.1 Apr 11, 2012, Stable

Thanks for the answer!

Comments: Hi! I fixed this problem. The main reason for the exception is, that Microsoft allows you to put INVALID hyperlink to the cells. I put this value in a cell: ecsomany@google:huszar and I hit enter in my Excel, than a hyperlink was created, however, the link is invalid. (mailto: ecsomany@google:huszar) Sad, that in Office 2013 is this bug present too... In your code: if you found Hyperlink in the worksheet, you try to parse it, and the invalid URI exception occours. I checked out the source of your latest version and modified only one method, you can use it. In ExcelWorksheet.cs at line 784 is a method, which load and validate the hyperlinks: called LoadHyperLinks In the third if section I wrote a catch, if any exception occours by parsing the Uri. In this case I set cell.Hyperlink = new Uri(""); ``` if (xr.GetAttribute("id", ExcelPackage.schemaRelationships) != null) { cell.HyperLinkRId = xr.GetAttribute("id", ExcelPackage.schemaRelationships); try { var uri = Part.GetRelationship(cell.HyperLinkRId).TargetUri; try { if (uri.IsAbsoluteUri) { cell.Hyperlink = new ExcelHyperLink(HttpUtility.UrlDecode(uri.OriginalString)); } else { cell.Hyperlink = new ExcelHyperLink(HttpUtility.UrlDecode(uri.OriginalString), UriKind.Relative); } } catch { //We should never end up here, but to aviod unhandled exceptions we just set the uri here. JK cell.Hyperlink = uri; } } catch { //if the hiperlink is invalid, just ignore and reset the link to empty URL cell.Hyperlink = new Uri(""); } Part.DeleteRelationship(cell.HyperLinkRId); //Delete the relationship, it is recreated when we save the package. } ``` I attached my solution CS file.

Created Unassigned: Slight issue with AutoFitColumns [14857]

krillgar — Wed, 15 May 2013 19:19:13 GMT

I just found this library, and am amazed at how easy it is to work with. Thanks!

I did notice one slight issue though. I found
```
ws.Cells.AutoFitColumns();
```
to try and Auto Fit the columns (I know, it was a stretch). However, there is a slight anomaly with it.

In my attached image, you'll notice that the last column has an increased width, however it doesn't max to the size of all of the text.

Since I'm using the default method call, is there a "hidden" maximum that it hit and stopped? If that wasn't the last column, would it have filled in all of the way like the other columns?

New Post: Need help with multi-level outlining

CoolBreeze812 — Wed, 15 May 2013 15:32:18 GMT

I'm having a really tough time trying to get multi-level outlining applied properly. I have 5 loops of collections that I'm trying to apply outlining to, but it is only placing everything under outline level 1 and ignoring the rest.

Below is a snippet of what I have:

foreach (var publisher in Publishers)
{
     worksheet.cells[pubRow, 1].Value = publisher.Name;
     worksheet.Row(pubRow).OutlineLevel = 1;

     foreach (var author in Authors)
     {
          worksheet.cells[authorRow, 2].Value = author.Name;
          worksheet.Row(pubRow).OutlineLevel = 2;

          foreach (var book in Books)
          {
               worksheet.cells[bookRow, 3].Value = book.Title;
               worksheet.cells[bookRow, 4].Value = book.ISBN;
               worksheet.cells[bookRow, 5].Value = book.Edition;
               worksheet.cells[bookRow, 6].Value = book.Pages;
               worksheet.row(bookRow).OutlineLevel = 3;
               bookRow++;
          }
     }
}

Can anyone help?

When I read the xlsx file, all cells seem to have the same Cells[...].Style.Font.Itallic/Bold/Strike etc.

In other words, itallic and other properties always seem to be true, whether the cell's style is itallic or not.

Anyone else had any trouble with this?

New Post: Xltx files

Peter_Karlstrom — Tue, 14 May 2013 13:30:45 GMT

Hi xav2075

Your sample is working unless you don't attempt to work with the worksheets using EPPlus afterwards.
I also found this sample on OpenXML forums and have used it for creating Excel spreadsheets from Excel XLTX templates.

But when I try to use the created spreadsheet using EPPlus after the change of documenttype, EPPlus cant find the sheets collection.

Studying the XML code after changing the documenttype using Open XML Producticity code, one can se that the the rootname of the workbook is changed from "workbook" to "workbook2".
This seems to be the cause of EPPlus not finding any sheets after the "conversion".

Do you (or anybody) have some mor input regarding this?

Thanks in advance

Created Unassigned: Is there a way to pass DataTable while creating CHART in a Worksheet? [14855]

vips3483 — Mon, 13 May 2013 14:16:13 GMT

Is there a functionality to pass a DataTable, to Create Chart or Multiple Charts in a single Worksheet ?

If yes , please guide me.
If no, please let me know a workaround for the same, if possible.

As I have to create Multiple Charts in a Single Worksheet to which I would pass 2-3 different DataTables without writing the DataTable in Excel Sheet.

I am stuck with this scenario, rest all has worked perfect for me, using the Excellent EPPLUS dll.

Many Thanks.

Created Unassigned: Character values - issue [14854]

punitganshani — Mon, 13 May 2013 11:27:11 GMT

While assigning a character value to a cell, EPPlus puts a value 0 to the cell. The workaround we have opted for is to check for the type of the value and then convert character value to string and then store it in the cell.

Is there any better way or known solution for this?
