And I found another issue, if I export a excel(*.xlsx) file from ReoGrid, then I open it by MS OFFICE 2010, it always popup a alert dialog, it says some unreadable content, and ask me “if recover the workbook or not, click ‘YES’ …… “, after I click YES, office excel prompt ‘have deleted part of style of /xl/styles.xml’.
And it works well except the popup. Maybe it cause by the compatibility between OFFICE 2007 and 2010

Hi. Can I open an existing xls or xml spreadsheet into the control, make some changes to data, and then save it back to the file?
Hi. Excel .xls format is not supported. You can open Excel 2007 and later (.xlsx) format into the control, makes changes and save it back. Some settings to the Excel file may lose if they aren’t supported by ReoGrid. https://reogrid.net/document/excel-file-format/
I had tried Excel 2007 too but it failed. I realise now that it probably failed because I loaded a spreadsheet with formatted text in it which displays on-screen but obviously causes it to fail when saving or printing because I’m using the free version which doesn’t support rich text.
A shame because I can’t justify $760 for the full version just for the sake of rich text (thats more expensive than Crystal Reports)

Is it still closed source? I’m missing some customization regarding AutoFillSerial and went to the forums for help. Funny enough I saw the suggestion to the change the source code, as an answer to a similar question I was about to ask. So I googled for source code and found Reogrid on Github:
The MIT license matches, the version number and the support for WinForms, WPF and Android. So I was wondering, is your reply to Jeffrey Kesselman in 2015 still up relevant? Or have you gone back to open source again in the meantime?
It’s fully open source software since 2017, under MIT license. The source code on Github is the latest version. What is your question? You can post it at https://github.com/unvell/ReoGrid/issues
Ok, cool! Might I suggest you change the text at the top of this FAQ page. At the heading ‘License’ it mentions Reogrid is closed source.
I’ll post my issues and questions to github if I find any worth bothering you about. Right now I’m just toying around and don’t want to make an issue out of everything. Short version: I was looking for supplying custom incrementing behaviour when using AutoFillSerial for custom cellbody’s and/or custom datatypes. I looked at the source, and there appears to be no support for it. So my question is answered. 🙂
Thanks! Page is edited.
I have two sheets not in the same workbook, the second sheet has formulas referencing to the first. When i add the second sheet in the workbook of the first sheet, the cells that have formula with reference do not update, but they still have the formula, if i copy/paste the formula in different cell it works. I tried .recalculate but that doesn’t help.
