What Is 10Tec iGrid and When Should You Use It Instead of DataGridView or MSFlexGrid?

10Tec iGrid is a commercial grid control from 10Tec that ships in two editions: iGrid ActiveX for classic platforms (VB6, VBA, VSTO, Access) and iGrid.NET for WinForms (VB.NET/C#). You should consider it when the built-in grid you're using — DataGrid, DataGridView, ListView, or MSFlexGrid — can't deliver what your UI needs, particularly if you need an unbound grid, an editable list view, or flicker-free drawing. If your project is a straightforward data-bound WinForms form and DataGridView already behaves well, there's no reason to switch.

What iGrid actually is

iGrid is described by 10Tec as its flagship grid control, positioned as a "powerful and super-fast replacement" for the ActiveX/.NET DataGrid and DataGridView controls that ship with VB6 and Windows Forms .NET. It is also positioned as an editable replacement for ListView and VB6 MSFlexGrid, with what the vendor describes as better functionality and optimized flicker-free drawing.

Two things follow from that positioning:

• It's a replacement control, not a framework. You drop it into an existing host (a VB6 form, a WinForms form, a VBA UserForm) in place of the built-in grid.
• It's explicitly aimed at unbound scenarios. 10Tec states the component is "the ideal choice if you need an unbound grid control for ActiveX/.NET development." That's the clearest signal about intended fit.

The vendor also emphasizes a simple object model, claiming you can start using it in minutes.

Platform and language support

The ActiveX edition is documented as working "perfectly" in Microsoft Word and Excel as a VBA grid control on UserForms, and as a versatile Access grid control. The .NET edition targets WinForms specifically — this is not a WPF, ASP.NET, or cross-platform control.

When to choose iGrid over the built-in alternatives

Use these as decision conditions rather than a blanket recommendation:

Choose iGrid when:

• You need an unbound grid — you're managing rows and cells yourself rather than binding to a DataTable or data source.
• You need an editable list with more capability than ListView provides.
• You're on VB6 or VBA and MSFlexGrid or the old DataGrid is limiting you, or you need a grid inside a Word/Excel UserForm or an Access form.
• Flicker during redraw is a real problem in your current control.
• You want a single control family across a mixed ActiveX and WinForms codebase.

Stay with the built-in control when:

• Your WinForms app is comfortably data-bound and DataGridView meets your needs.
• You're targeting a UI stack outside WinForms/ActiveX (WPF, web, mobile).
• You don't want a third-party dependency in the project.

The comparison dimensions that matter here are: bound vs. unbound usage, editability, drawing quality, host platform, and language. iGrid's stated advantages cluster on the unbound, editable, and drawing-quality axes — not on data binding, where DataGridView is already strong.

Current version highlights worth factoring into a decision

The most recent release noted on the site is iGrid.NET 14, described as a major update (the version jump from 12 to 14 reflects the scale of changes). Relevant points for evaluating fit:

• Dark mode support, aligned with the full dark mode support officially integrated into Windows Forms in .NET 10. The grid ships in separate .NET 10 builds with built-in support for this mode.
• Improved high-DPI support.
• A simpler system for controlling the overall rendering style of the control.
• New properties for finer control over color appearance in both light and dark UIs.
• The demo installation includes a new sample showing the grid's main visual features in dark mode.

There is also a separate ActiveX news item (December 2025) about HKCU and HKLM registration for modern editions of the ActiveX controls, with two sets of OCX files now provided. If you deploy ActiveX controls in environments where per-user vs. machine-wide registration matters, that's worth reading before you plan deployment.

If you're building on .NET 10 WinForms and want dark mode to work naturally, iGrid.NET 14 is the version to evaluate — earlier builds predate that integration.

How to verify fit before committing

1. Download the demo from the iGrid.NET or ActiveX home page and install it.
2. Run the included samples, including the dark mode sample in the .NET 14 demo, to see rendering behavior on your own display and DPI settings.
3. Rebuild one screen of your real application with iGrid in place of your current grid, focusing on the specific pain point — unbound editing, flicker, or VBA hosting.
4. Check the What's New document for the version you're evaluating to confirm the specific properties and behaviors you depend on.
5. Confirm your deployment path, especially for ActiveX, where the HKCU/HKLM registration options affect how the control is installed on end-user machines.

The vendor's claim of a simple object model means step 3 should be quick to test — that claim is itself worth verifying in your own code before you standardize on the control.

What the source material does not tell you

The site content provided does not include pricing, licensing terms, or whether a free tier exists. Do not assume the control is free or that the demo implies no-cost production use — check the vendor's licensing page directly. It also doesn't cover performance benchmarks against DataGridView, so any "super-fast" claim should be validated against your own data volumes rather than taken as a measured comparison.
