c# - 无法确定元表

Question

我有一个带有 FormView 和 SQLDataSource 的简单应用程序。当我选中“启用动态数据支持”时，出现以下错误:

Could not determine a MetaTable. A MetaTable could not be determined for

the data source 'SqlDataSource1' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute.

有什么想法吗？

Answer 1

对我来说，事实证明在我的 GridView 中，列被绑定(bind)为“asp:DynamicField”，而不是“asp:BoundField”

即

像这样改变我的专栏:

<Columns>
  <asp:DynamicField DataField="Id" HeaderText="Id" />
</Columns>

为此:

<Columns>
  <asp:BoundField DataField="Id" HeaderText="Id" />
</Columns>

修复它 ;-)
