Farpoint Spread 7.0.25

Title: Still maintaining a legacy app with FarPoint Spread 7.0.25 (v7.0.25) – need a sanity check

Body:

I know we’re way behind, but I’ve got a WinForms app stuck on FarPoint Spread 7.0.25 (Spread for Windows Forms). Before anyone says “just upgrade to v15+”, trust me, I’d love to. Budget/legacy constraints.

I wanted to share some pain points and see if anyone else is still dealing with this specific build (7.0.25.0) and has found workarounds.

Environment:

• .NET Framework 3.5/4.0 (mixed)
• Visual Studio 2015 (don’t laugh)
• Windows 10 (mostly)

The good (surprisingly):

• Virtual mode still handles 100k+ rows without dying.
• fpSpread1.ActiveSheet.Cells[row, col].Value is predictable.
• Printing via PrintSheet() works on old Zebra printers.

The ugly (please tell me I’m not alone):

1. High DPI / scaling disaster – On 4K monitors, the cell editor shrinks to 4px high. Setting AutoSizeMode does nothing. Had to force fpSpread1.ScaleRatio manually – partial fix.
2. ComboBox cell type bug – When you set EditorValue = EditorValue.ItemData, the Changed event fires twice. The second time Cell.Text is empty. My workaround is a debounce timer (hacky).
3. Copy/paste with locked columns – If you lock column B, users can still paste into it via Ctrl+V if selection includes B+C. FarPoint confirmed this as a “by design” behavior back then – still annoying.
4. Memory leak – Opening/closing a form with a Spread control repeatedly adds ~2-4 MB per instance (even after calling Dispose()). I finally added fpSpread1.Sheets.Clear(); fpSpread1.Dispose(); and called GC.Collect() – still leaks but slower.

The question: Has anyone backported the v8 hotfix for the CellChanged double-event issue to v7.0.25? Or am I stuck with the debounce?

Also – if you upgraded from 7.0.25 to a later version (even v9 or v10), what broke the hardest? I need to build a business case.

Version details:

FarPoint.Win.Spread, Version=7.0.25.0, Culture=neutral, PublicKeyToken=327c3516b1b18457

Thanks in advance.

Edit 1: Yes, I’ve tried the Spread 7.0.25.1 hotfix – didn’t fix the ComboBox double-event.
Edit 2: If you’re on FarPoint 7 and also dealing with InvalidOperationException when sorting by date columns, comment below.

Yes, if installed via Visual Studio 2010/2012 on Windows 11, and if the application targets .NET Framework 4.0 or 4.5, it runs without issues. No native Windows 11 features (rounded corners, dark mode) will apply to the grid. The good (surprisingly):

2. The "GrapeCity" Transition

The truly interesting backstory: FarPoint Technologies was acquired by GrapeCity (a Japanese software giant) in 2013. Version 7 is pre-acquisition. So version 7.0.25 represents the "classic" FarPoint codebase, before the licensing and branding changed to GrapeCity Spread. Developers who cling to version 7 often do so because the newer versions (8, 9, 10+) changed the object model significantly.

Q2: Can I use it in a web application?

No. Version 7.0.25 is strictly a Windows Forms control. For web, GrapeCity offered Spread for ASP.NET (separate product).

7.1 The

Once upon a time in the world of Windows development—back when Visual Basic was king and COM (Component Object Model) was the standard—there was a legendary tool that every developer wanted in their utility belt: FarPoint Spread. The Era of "Spread"

In the early 2000s, FarPoint Spread 7.0 was the "gold standard" for adding Excel-like power to desktop applications. Version 7.0.25 specifically was one of those reliable, late-cycle builds that developers clung to because it was stable and packed with features that seemed like magic at the time: What Happened to FarPoint Spread? | Spread.NET & SpreadJS.

The Grid of Dreams: Developers used it to create massive data entry screens. It wasn't just a grid; it had "cell types," meaning you could turn a single cell into a checkbox, a combo box, or even a date picker with a few clicks.

Excel Without Excel: It allowed users to perform calculations and format cells exactly like they would in Microsoft Excel, but all tucked safely inside a custom-built corporate app FarPoint Spread - Wikipedia. The "FarPoint" Legacy

As the tech world shifted from COM to .NET, the story of FarPoint took a major turn. In 2009, FarPoint was acquired by GrapeCity (now known as MESCIUS) What Happened to FarPoint Spread? | Spread.NET & SpreadJS.

The "FarPoint" name was eventually dropped, but the DNA of version 7.0 lived on. It evolved into:

Spread.NET: The modern successor for Windows Forms and ASP.NET. SpreadJS: A high-speed JavaScript version for web apps. Where is it Now?

If you find a copy of FarPoint Spread 7.0.25 today, you're looking at a piece of software history. While the industry has moved to the cloud and mobile apps, many "legacy" systems in banks and factories still run on this classic engine.

For those still needing support or looking for the modern version of that classic 7.0 feeling, you can find the current iterations at MESCIUS (formerly GrapeCity). NET environment?

That's an intriguingly specific reference: FarPoint Spread 7.0.25.

While I don't have a pre-existing "interesting story" directly attached to that exact version number, I can tell you why this version is a notable piece of software archaeology, and perhaps you have the missing piece of the story.
