範例
以下程式碼範例定義了 Web 表單頁面中 Wizard 控制項的三個精靈步驟。 在該頁面的程式碼中,精靈步驟實例以其 ID 值命名,且可在程式碼 WizardStep1中以 、 WizardStep2、 WizardStep3和 作為參考。

備註
使用該 ID 屬性來識別並參考網頁表單頁面中特定的精靈步驟控制項。 該 ID 值會成為頁面中控制實例的名稱;這讓你能輕鬆存取該頁面程式碼中的特定步驟。 例如,如果你將某WizardStepBase個控制項的屬性設ID為「Step1」,你可以在程式碼中參考該頁面的精靈步驟的子控制項。Step1.Controls
控制項確保 WizardStepBase 在設計時新增或修改步驟時,控制項中的每個步驟 Wizard 都有有效的唯一識別碼。 例如,當你在設計時設定 步驟的 時ID,它無法匹配控制項中其他Wizard步驟的識別碼,也無法匹配包含Wizard控制項的 。ID
