无法编辑单元格是 ASP.Net 4.0 / Visual Studio 2010 中的 Infragistics We

Question

当我双击一个单元格时，我的基础设施WebDataGrid不会进入单元格编辑模式。它不会进入服务器模式 - 没有任何反应。只有客户端事件发生，但我怀疑这些是必要的。以下 asp.net 段有什么问题？

<infra:WebDataGrid ID="wdgProjects" runat="server" EnableAjax="true" AutoGenerateColumns="False"
                        DataSourceID="sqlProjects" DataKeyFields="ProjectID"

使用 TemplateDataField 时，模板中的控件将始终显示，除非您在模板中实现，否则这些单元格没有编辑模式。 如果您正在寻找可以双击以编辑单元格的默认行为，则应改用 BoundDataField。 如果完成此操作，则网格将使用您在"列设置"中指定的编辑器进行单元格编辑行为。
