FormView控件是ASP.NET
2.0工具箱引入的，它的工作方式類似于DetailsView控件，也是顯示綁定數(shù)據(jù)源控件中的一個(gè)數(shù)據(jù)項(xiàng)，并可以添加、編輯和刪除數(shù)據(jù)。它比較獨(dú)特的
地方是在定制模板中顯示數(shù)據(jù)，可以更多地控制數(shù)據(jù)的顯示和編輯方式。圖7-35顯示了在Visual
Studio中編輯的FormView控件ItemTemplate。從中可以看出，我們能完全控制數(shù)據(jù)的顯示方式。FormView控件還包含
EditItemTemplate和InsertItemTemplate，它可以確定控件在進(jìn)入編輯或插入模式下的顯示方式。
