備註
分隔符可讓您放置在每個群組之間具有自定義內容的專案。 控件 ListView 接著會轉 GroupTemplate 譯內容和 GroupSeparatorTemplate 內容。 內容 GroupTemplate 一律會最後轉譯。
請確定您在範本中GroupSeparatorTemplate定義整個資料列的內容,因為ListView控件會在範本內LayoutTemplate呈現GroupSeparatorTemplate內容。 例如,控件中的 ListView 群組可能會使用數據表數據列 () tr
元素來建立。
GroupItemCount如果屬性設定為 3,則colspan
屬性必須在範本中GroupSeparatorTemplate設定為 3。
若要以宣告方式指定分隔符的範本,請在控件內ListView加入 GroupSeparatorTemplate
專案。 然後,您可以將範本的內容新增至 GroupSeparatorTemplate
元素。
