Question

My Infragistics当我双击一个单元格时，WebDataGrid不会进入单元格编辑模式。它没有进入服务器模式 - 没有任何反应。只发生客户端事件，但我怀疑这些事件是必要的。下面的asp.net段有什么问题？

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

                        OnActiveCellChanged="wdgProjects_ActiveCellChanged"

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，那么您应该使用BoundDataField。如果这样做，那么网格将使用您在ColumnSettings中为CellEditing行为指定的编辑器。

无法编辑单元格是ASP.Net 4.0 / Visual Studio 2010中的Infragistics WebDataGrid。为什么？
