Designer Verbs

Local maintainer notes for WinForms designer verbs (ComponentDesigner.Verbs) versus smart tags (DesignerActionList). Do not include this file in pull requests.

Two surfaces

Surface	API	Where it appears
Smart tag	DesignerActionList	Glyph panel on the selected component
Designer verb	ComponentDesigner.Verbs	Bottom of the component context menu

Commands belong on verbs. Properties belong on smart tags. KryptonDesignerActionItem wraps a DesignerVerb for the smart tag only (IncludeAsDesignerVerb is false). Do not flip that flag on designers that also override Verbs — the same command would appear twice.

Newer Utilities lists that do not override Verbs may pass includeAsDesignerVerb: true on DesignerActionMethodItem (radial menu, enhanced context menu). That is the other valid pattern; pick one per designer.

When to add a verb

Add a verb when the action does something (add/remove a child, insert a template, import/export, open a collection editor) and native WinForms has a similar command, or the command is hard to discover from the property grid.

Skip verbs for property toggles (Checked, palette mode, styles, orientation). Those stay as smart-tag property items.

How to implement

Copy KryptonNavigatorDesigner / KryptonMenuBarDesigner:

1. Cache DesignerVerb instances in a DesignerVerbCollection (do not rebuild on every get).
2. Mutating verbs use IDesignerHost.CreateTransaction and IDesignerHost.CreateComponent.
3. Notify IComponentChangeService so the designer serializes.
4. Enable/disable with UpdateVerbStatus on ComponentChanged when state matters. DesignerVerb.Text is read-only in current TFMs — use a fixed label (or a pair of enabled/disabled verbs), not a rewritten caption.
5. Share the handler between the designer and the action list (static methods on the designer, or a small *DesignerActions helper). Do not duplicate import/export dialogs.

KryptonDesignerCollectionActions.EditProperty opens a collection UITypeEditor from a verb (used by Edit Items... on KryptonContextMenu).
