PowerApps 中的資源庫控制項Gallery control in PowerApps

包含其他控制項並顯示一組資料的控制項。A control that contains other controls and shows a set of data.

說明Description

資源庫控制項可以顯示資料來源中的多筆記錄,而且每一筆記錄都可以包含多種類型的資料。A Gallery control can show multiple records from a data source, and each record can contain multiple types of data. 例如,資源庫控制項可以顯示多個連絡人,而其每個項目都會顯示包括每位連絡人的名稱、地址和電話號碼的連絡資訊。For example, a Gallery control can show multiple contacts with each item showing contact information that includes a name, an address, and a phone number for each contact. 每個資料欄位都會出現在資源庫控制項的不同控制項中,而且您可以在其範本中設定這些控制項。Each data field appears in a separate control within the Gallery control, and you can configure those controls in its template. 範本會顯示為資源庫內的第一個項目、顯示在水平/橫向的資源庫控制項左邊緣,以及顯示在垂直/直向的資源庫控制項頂端。The template appears as the first item inside the gallery, on the left edge of a Gallery control in horizontal/landscape orientation and at the top of a Gallery control in vertical/portrait orientation. 您在範本中進行的任何變更都會反映在整個資源庫控制項中。Any changes that you make in the template are reflected throughout the Gallery control.

提供預先定義的資源庫範本,以顯示影像、文字,以及具有變動高度項目的資源庫。Predefined Gallery templates for showing images, text as well as a gallery with variable height items are available.
