推荐答案

ConceptQuestionsDataSource是你的DataGrid或DataView还是DataReader？如果是，那么请检查您是否在页面上放置了相同的内容。因为它只与名为ConceptQuestionsDataSource的控件有关。

"ConceptQuestionsDataSource" is your DataGrid or DataView or DataReader? if yes then please check whether you have placed the same on Page or not. because it is only related to the control named "ConceptQuestionsDataSource".

因为你使用第三方工具（代码smith）生成代码，所以Microsoft .net无法理解datagrid属性数据：ConceptQuestionsDataSourcehere数据完全无法识别.net。



所以代替：

< data：conceptquestionsdatasource id =ConceptQuestionsDataSourcerunat =serverxmlns：data =＃unknown>



提及

< asp：gridview id =GridView1runat =serverxmlns：asp =＃unknown>



请试试。

because you have generated the code using third party tool (code smith) somehow Microsoft .net is unable to understand the datagrid attribute "data:ConceptQuestionsDataSource" here, "data" is completely unrecognised by the .net.

So instead of:
<data:conceptquestionsdatasource id="ConceptQuestionsDataSource" runat="server" xmlns:data="#unknown">

Mention
<asp:gridview id="GridView1" runat="server" xmlns:asp="#unknown">

Kindly try.
