Definice

Obor názvů:
System.Windows.Forms.Design
Sestavení:
System.Windows.Forms.dll

Umožňuje interakci s uživatelským rozhraním objektu vývojového prostředí, který je hostitelem návrháře.

Příklady

Následující příklad kódu vytvoří návrháře, který poskytuje příkazy nabídky návrháře, které volají metody .IUIService Pokud chcete příklad použít, zkompilujte ukázkový kód do sestavení a přidejte odkaz na sestavení v model Windows Forms aplikaci. Pokud používáte Visual Studio, IUIServiceExampleControl automaticky se přidá do panelu nástrojů. Přidejte instanci objektu IUIServiceExampleControl do souboru Form. Pokud chcete získat přístup k příkazům návrháře, které volají IUIService metody, klikněte pravým tlačítkem myši na plochu ovládacího prvku nebo klikněte na inteligentní značku ovládacího prvku a vyberte položku z panelu inteligentních značek.
