GridView与checkbox的问题
我在GridView中加入的是HTML的checkbox,我怎样实现选择删除行?
给你发一个我自己做的例子吧！试试看。
aspx：
<html xmlns="http://www. >
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" style="text-align:center" runat="server">

<legend style=" float:left; font-weight:normal; font-size:12px" >稿件分审</legend>
