New Post: Cannot open password protected file (Excel 2007)

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

Nick

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?

New Post: Doesn't seem to read font styles correctly

SamiHuutoniemi — Wed, 15 May 2013 10:18:48 GMT

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

New Post: Unable to retrieve the background color of a cell

mparter — Tue, 07 May 2013 10:24:02 GMT

It seems that no matter what the background color is of a cell in a workbook, the

Sheet.Cells[1, 1].Style.Fill.BackgroundColor.Rgb

property is always an empty string. I've also tried using

Sheet.Cells[1, 1].Style.Fill.BackgroundColor.Indexed

and

Sheet.Cells[1, 1].Style.Fill.BackgroundColor.Tint

and whilst these return values, they are always the same regardless of the color of the cell. So, is it possible to retrieve the background color of a cell?

New Post: Invalid Address format: (tablename)[(tablefield)] Exception

mjoyce19 — Mon, 06 May 2013 18:11:41 GMT

Just an FYI for those using EPPlus for reading data formatted in a table. I created a file with a tab with two tables that referenced each other via Vlookups and DataValidation dropdown lists. Anyways, when trying to set the worksheet to a variable, I was getting an exception:

Invalid Address format: mytablename[mytablefield]

No matter how many different names I tried, I still got this exception. Finally, I decided to remove the table format, and then recreate the table, using the same tablename and field names which fixed the issue.

I have no clue why this exception was occurring but I just wanted to post this in case someone else runs into this problem in the future.

New Post: Page number from cell

deverion — Mon, 06 May 2013 08:40:58 GMT

Is it possible to determine which print page a given cell is on?

I would like to print table headers on every page. (I do not want to use 'Print Titles' Excel feature, because I would like to customize the titles on every page)

My spreadsheet is "one printer page" width and usually contains 34 rows / page, so most of the time I know when 'I am on a new page'. But some cells have word wrap on, so they consumes multiple rows.

Should I count the height of rows? Any idea?

Thank you very much!
