TMS Flexcel Studio for .NET Changelog

What's new in TMS Flexcel Studio for .NET 7.21

Feb 25, 2024
  • New: Support for exporting Persian to PDF
  • Fixed: When rendering charts that had labels linked to "Value from Cells" FlexCel could fail to render the labels if they weren''t manually specified.
  • Fixed: There was an error when rendering PDF Khmer text in some corner cases.
  • Fixed: SetCellFromHtml could raise an exception with some surrogated unicode characters.
  • Fixed: Reviewed bidi algorithm because some arabic numbers could be written in the wrong order when exporting to PDF
  • Fixed: Header images wouldn''t be copied when calling the InsertAndCopySheets overload that takes an array of integers for the sheets to copy.
  • Fixed: Data labels in scatter chart were incorrect when the axis was reversed.
  • Fixed: Charts with hidden series could raise an exception when drawing trendlines.

New in TMS Flexcel Studio for .NET 7.20 (Dec 10, 2023)

  • New : Updated SKIASharp
  • New : Support for creating your own cultures when rendering Excel files
  • New : Support for .NET 8
  • Improved : Removed canvas.getMatrix calls in Android as they are deprecated
  • Improved : New setting FlexCelConfig.LocalizedTEXTFunction allows you to fine tune how FlexCel recalculates the "=TEXT()" function
  • Improved : Improved Label rendering when drawing charts
  • Improved : FlexCel is more forgiving with too long data validation formulas
  • Improved : Better support for subnormal numbers
  • Fixed : When parsing some PNGs FlexCel could raise an arithmetic overflow.
  • Fixed : When drawing Error Bars in charts, if there was no line color assigned, FlexCel would not draw the lines instead of drawing them in Black.
  • Fixed : When autofitting rows FlexCel ignored empty columns formatted with big fonts.
  • Fixed : The XLOOKUP function would return "not found" when searching for a value bigger than any on the list and the match mode was "Exact match or next larger item", when there were empty entries in the list. This is the logical way to do it, it is how Google Sheets does it, and it is how Excel itself behaves in the other match modes. But for this match mode, Excel returns the first empty item in the list, not "not found". Now FlexCel mimics this behavior.
  • Fixed : The SINGLE function could return wrong results in very special cases.
  • Fixed : Some files could show the error: "Value was either too large or too small for an Int32" when opened.
  • Fixed : If the column names of a table had a format like "@_@" or similar, FlexCel would apply them and the column name would be wrong. Now the names are the same as in Excel. Some other improvements in handling of column names.
  • Fixed : FlexCel could fail to detect circular references in some corner cases, causing a Stack Overflow.

  • Fixed : The **Last print time** document property wasn't read in xlsx files.
  • Fixed : Modified and creation time were read in UTC, but saved in local time which would result in a different date being saved back. Now it is all handled in UTC.
  • Fixed : In some very complex bidirectional reports with sorting in the template the fields might end up not being sorted correctly, and some might appear twice.
  • Fixed : Formulas referencing sheets which could be interpreted like a R1C1 cell reference (like "R3C5") were saved without quotes in the sheet name, and thus became invalid formulas.

New in TMS Flexcel Studio for .NET 6.17.3.0 (Oct 10, 2017)

  • Fixed : When doing bidirectional reports with multiple horizontal master detail X ranges, the rows for the vertical ranges could be wrong.
  • Fixed : When a SPLIT tag was used inside a multiple master-detail relationship in a report the results could be wrong.
  • Fixed : The parameters MaxWidth and MinWidth of the <#column width> and <#row height> tags weren't working properly when autofitting. Now they work according to the docs. If you were using MaxWidth and MinWidth in or please review those tags and make sure minwidth and maxwidth are in the correct positions.
  • Fixed : Setup wasn't correctly registering the .NET 4 and newer assemblies in Visual Studio, so those wouldn't appear in the "Add reference" dialog as Extensions. (They were still available if you browsed for them)
  • Fixed : Row() and Col() functions would return 1 when called from <#Format range> or <#Delete range> tags. Now they return the row and column of the cell where the tag is written.

New in TMS Flexcel Studio for .NET 6.15.0.0 (May 22, 2017)

  • Fixed : When exporting to SVG, text in controls or shapes could go a little lower than it should.
  • Fixed : When exporting to HTML with embedded SVG images, the fill colors in the SVG images would be wrong if there were gradients.
  • Fixed : When exporting to HTML and a merged cell covered hidden rows or columns, the resulting html could be wrong.
  • Fixed : When a file had "Precision as displayed" set and there were cell formats including percentage signs, the numbers might be rounded wrong.
  • Fixed : There could be an stack overflow when a camera object rendered a range of cells which included the cells where the camera object was.
  • Fixed : The formula parser would fail to detect some unicode characters as valid characters for a sheet name or named range.
  • Fixed : Now FlexCel allows names with spaces as macro identifiers when loading files. While those aren't valid names and Excel won't let you enter them directly, you can enter them with VBA code, and FlexCel was refusing to read those files. Now FlexCel will open them correctly.
  • Fixed : In .NET Core we could fail to read formulas

New in TMS Flexcel Studio for .NET 6.12.0.0 (Dec 16, 2016)

  • Fixed : When copying sheets in a file, some conditional formats could raise a null reference exception.
  • Fixed : In xls files, setting SheetProtection.Scenarios and SheetProtection.Objects had the reverse effect as in xlsx files. Now xls files behave the same as xlsx files. If you are changing the protection of xls files, **review the calls to `SheetProtectionOptions.Objects` and `SheetProtectionOptions.Scenarios` as they might be reversed.** If you are saving as xlsx files, then there is no need to change anything, as xlsx already worked as expected.

New in TMS Flexcel Studio for .NET 6.11.0.0 (Dec 16, 2016)

  • New : While it is invalid to write a file with conditional formats or data validations with formulas that refer to other sheets, Excel can load them (but you won't be able to modify them). Now FlexCel can read those too without reporting an error.

  • Fixed : When deleting sheets with locally stored defined names and you had multiple references to those names in a single formula, FlexCel could fail to update the names.
  • Fixed : Now FlexCel won't let you enter formulas with unions ranges of numeric or string values. Before it would allow you to enter a formula like "=1, 2" and it would be interpreted as the union of the reference "1" and "2". Excel would read it if saved as xls, but would fail to parse the formula when saved as xlsx. So now we don't allow those formulas anymore.
  • Fixed : In form objects like checkboxes or listboxes saved by Excel 2007 in xlsx files, the resulting coordinates could be wrong if the value of the anchor took more than one cell. FlexCel would move the anchor to the next cell, but Excel just ignores the extra width or height. Note that this only applies to xlsx files saved by Excel 2007, xls files or xlsx files saved by Excel 2010 or later would be correctly read by FlexCel.
