推荐答案

嗨错误很清楚。我认为你应该制作一个表格标签并在该表格标签中设置属性runat = server。







/////其他编码在这里//////

Hi The error is very clear. I think you should make a form tag and set the property runat=server in that form tag.



/////other coding goes here //////

你忘了用 runat =server设置表格标签



试试这个.. :)

you forgot to set Form tag with runat="server"

try this.. :)

<form id="grnData" runat="server">

//Do your stuff here..

</form>
