無法編輯單元格是ASP.Net 4.0/Visual Studio 2010中的Infragistics WebDataGrid。爲什麼？

Question

雙擊單元格時，我的Infragistics WebDataGrid不進入單元格編輯模式。它不進入服務器模式 - 沒有任何反應。只有客戶端事件發生，但我懷疑這是必要的。下面的asp.net部分有什麼問題？

<infra:WebDataGrid ID="wdgProjects" runat="server" EnableAjax="true" AutoGenerateColumns="False"

當使用TemplateDataField在模板中的控件將在任何時候都可以顯示並沒有，除非你實現你的模板內的編輯模式這些細胞。如果您正在尋找可以雙擊編輯單元格的默認行爲，則應該使用BoundDataField。如果這樣做，那麼網格將使用ColumnSettings中爲您的CellEditing行爲指定的編輯器。
