Visual Studio 2026 Notes
The following notes describe behaviors you may encounter when using SftTree/OCX in the Visual Studio 2026 Windows Forms designer, particularly with .NET 10 (or later) projects. These are limitations in the way Visual Studio 2026 hosts ActiveX controls in its designer and are not defects in SftTree/OCX. They affect ActiveX controls in general, and the control itself functions correctly in all cases.
Control Verb Menu (Smart Tag)
When the control is selected in the designer, the smart tag (the small flyout arrow menu attached to the control) and the control's verb entries may display garbled text prefixed with AXVerbPrefix instead of the expected Properties..., Help and About entries.
This is a Visual Studio 2026 rendering issue - Visual Studio fails to resolve its own resource string when it displays the verbs of an ActiveX control. The entries still work as expected; for example, the first entry still opens the control's property pages. You can also right-click the control and select Properties... directly.
Properties Window Categories
In the Visual Studio 2026 Properties window (the property grid), the control's properties are listed without category grouping. Visual Studio 2026's designer does not display the property categories of an ActiveX control.
To work with the control's properties in a fully organized form, use the control's property pages instead. Right-click the control and select Properties... (or use the Properties... verb on the control's menu). The property pages group all properties into tabbed pages by category and provide complete help for each property.
Properties Window Property Pages Button (Wrench Icon)
In the Visual Studio 2026 Properties window, the Property Pages toolbar button (the wrench icon) is always disabled and cannot be used to open the control's property pages.
To open the property pages, use the control's own menu instead - right-click the control and select Properties... (or use the Properties... verb on the control's menu).
