範例
下列程式代碼範例示範如何從 ControlDesigner 類別衍生自定義類別。 此控件設計工具支援具有四個可能範本的控制件。
若要嘗試,請將參考新增至 System.Design.dll 元件、編譯程式代碼,然後在Visual Studio 2005等設計主機中,查看 [設計] 檢視中的頁面。 選取控件,按兩下動作清單以選取要修改的範本,然後使用拖放功能將控件移至範本。

備註
類別 TemplateDefinition 提供基底範本定義類別,可繼承和擴充控件設計工具,以在設計主機中提供樣板化控件的支援,例如Visual Studio 2005。 設計主機會使用 類別的屬性 TemplateDefinition 和方法,在設計時間協助建立和編輯範本。
建構函式
TemplateDefinition(ControlDesigner, String, Object, String) |
使用所提供的設計工具、樣板名稱、樣板和屬性名稱,初始化 TemplateDefinition 類別的新執行個體。 |
TemplateDefinition(ControlDesigner, String, Object, String, Boolean) |
使用所提供的設計工具、樣板名稱、樣板、屬性名稱和是否將樣板內容限制為 Web 伺服器控制項,初始化 TemplateDefinition 類別的新執行個體。 |
TemplateDefinition(ControlDesigner, String, Object, String, Style) |
使用所提供的設計工具、樣板名稱、樣板、屬性名稱和 TemplateDefinition 物件,初始化 Style 類別的新執行個體。 |
TemplateDefinition(ControlDesigner, String, Object, String, Style, Boolean) |
使用所提供的設計工具、樣板名稱、樣板、屬性名稱、TemplateDefinition 物件和是否將內容限制為 Web 伺服器控制項,初始化 Style 類別的新執行個體。 |
屬性
AllowEditing |
取得值,這個值表示樣板是否應允許編輯其內容。 |
Content |
取得或設定 HTML 標記,表示樣板的內容。 |
Designer |

Name |
取得物件的名稱。 (繼承來源 DesignerObject) |
Properties |

ServerControlsOnly |
擷取值,指出樣板是否應將內容限制為 Web 伺服器控制項 (如同 TemplateDefinition 建構函式 (Constructor) 所設定)。 這個屬性是唯讀的。 |
Style |
擷取樣式,該樣式應套用至樣板 (如同 TemplateDefinition 建構函式所設定)。 這個屬性是唯讀的。 |

擷取樣板所在的元件。 這個屬性是唯讀的。 |
TemplatePropertyName |
擷取設計主應用程式應在屬性方格中顯示之樣板的屬性名稱。 |
方法
Equals(Object) |
判斷指定的物件是否等於目前的物件。 (繼承來源 Object) |
GetHashCode() |
做為預設雜湊函式。 (繼承來源 Object) |

MemberwiseClone() |
建立目前 Object 的淺層複製。 (繼承來源 Object) |
ToString() |
傳回代表目前物件的字串。 (繼承來源 Object) |
明確介面實作
