屬性

範例

下列程式碼範例示範如何使用 ShowMessageBox 和屬性, ShowSummary 指定驗證摘要同時顯示在訊息方塊和網頁上。The following code example demonstrates how to use the ShowMessageBox and ShowSummary properties to specify that the validation summary is displayed in both a message box and on the Web page.

重要

這個範例有一個可接受使用者輸入的文字方塊,這可能會造成安全性威脅。This example has a text box that accepts user input, which is a potential security threat. 根據預設,ASP.NET Web 網頁會驗證使用者輸入未包含指令碼或 HTML 項目。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 如需詳細資訊,請參閱 Script Exploits Overview (指令碼攻擊概觀)。For more information, see Script Exploits Overview.

備註

除了屬性之外,還可以使用這個屬性 ShowMessageBox 來控制驗證摘要的顯示位置。This property can be used in addition to the ShowMessageBox property to control where the validation summary is displayed. 如果這個屬性設定為 true ,則會在網頁上顯示驗證摘要。If this property is set to true, the validation summary is displayed on the Web page.

注意

如果 ShowMessageBoxShowSummary 屬性都設為 true ,則驗證摘要會顯示在訊息方塊和網頁上。If both the ShowMessageBox and ShowSummary properties are set to true, the validation summary is displayed in both a message box and on the Web page.
