推荐答案

如果在页面加载时未绑定数据，则可以使用空数据模板将用户报告为gridview中没有数据.
只需添加..

If you are not binding data on page load, you can use empty data template to report users as no data in gridview.....
just add..

<EmptyDataTemplate>
             No Data !
         </EmptyDataTemplate>

好吧，将数据获取和数据绑定代码放在页面加载中！
每次打开页面时都会显示Gridview.

Well, place your code of data fetch & data binding in your page load!
Gridview will be displayed whenever you open page.

编写这样的查询..

write a query like this ..

SELECT ItemID,ItemName FROM TableName
UNION ALL
SELECT 0,'' FROM TableName HAVING COUNT(*)=0 ";
