如何解决此Gridview错误
问题描述：
我发现此错误..
DataBinding：''System.Data.DataRowView''不包含名称为''applicatio_nno'的属性
DataKeyNames是隐藏字段的ID。
i已经采用模板字段来绑定数据。
请解决我的疑问

Replace \"applicatio_nno\" in the following line of your code with the \"column name\" returned by your query result:

<asp:label id="Label16" runat="server" text="<%# Bind("applicatio_nno") %>" xmlns:asp="#unknown"></asp:label>I think every place it says ’’Bind’’, it should say ’’Eval’’
I think every place it says ''Bind'', it should say ''Eval''
hey i think you have to check below line data field name Speling
hey i think you have to check below line data field name Speling
<asp:label id="Label16" runat="server" text="<%# Bind("applicatio_nno")%>"></asp:label>
You write :\"applicatio_nno\"
i think it should be wrong and should be like this. \"application_no\"
