在您的aspx文件中，请确保grdview中包含所有列.

In your aspx file make sure you have all the columns within grdview.

 <columns>
                        <asp:boundfield headertext="PRODUCT_GROUP_ID" datafield="PRODUCT_GROUP_ID" sortexpression="PRODUCT_GROUP_ID" xmlns:asp="#unknown">
                             />
                        <asp:boundfield headertext="PRODUCT_GROUP_DESC" datafield="PRODUCT_GROUP_DESC" sortexpression="PRODUCT_GROUP_DESC" />
                        
</asp:boundfield></columns>

还要确保您没有为要显示的任何列设置Visible ="false".

Also make sure you have not set Visible="false" for any of those columns you wanted to display.

我认为您在gridview中有AutoGenerateColumns="True"列，在查询中有只有两列(PRODUCT_GROUP_ID,PRODUCT_GROUP_DESC).***在查询中添加列，或者如果您的gridview列为AutoGenerateColumns="False"，然后将您的列绑定到Gridview中.

谢谢

I think you have AutoGenerateColumns="True" Column in your gridview and in your Query there is only two columns (PRODUCT_GROUP_ID,PRODUCT_GROUP_DESC). It''s better to add your columns in your query OR if your gridview columns are AutoGenerateColumns="False" then bind your Columns in Gridview.

Thanks
