備註

ButtonType當 物件的 屬性 ButtonField 設定為 Button 或 Link 值時，請使用 Text 屬性來顯示 中 ButtonField 按鈕標題的靜態文字。 每個按鈕都會共用相同的標題。

您可以使用 DataTextField 屬性將 系結 ButtonField 至資料來源中的欄位，而不是使用 Text 屬性來顯示物件中的靜態文字 ButtonField 。 然後，欄位的值會顯示為按鈕的標題。

注意

DataTextField如果 同時設定 和 Text 屬性，則 DataTextField 屬性會優先使用。

此屬性的值會儲存在檢視狀態中。

當設定時，此屬性的值可以使用設計工具自動儲存到資源檔。 如需詳細資訊，請參閱 LocalizableAttribute和全球化和當地語系化。
