加上runat="server"
属性 后台就可以用id来控制了
<div id="div1" runat="Server">
...
</div>
if(GridView1.Rows.Count > 0 )
{
div1.Style["Display"] = "Block"; //显示
}
else
{
div1.Style["Display"] = "None"; //隐藏
}
<div id="div1" runat="Server">
...
</div>
if(GridView1.Rows.Count > 0 )
{
div1.Style["Display"] = "Block"; //显示
}
else
{
div1.Style["Display"] = "None"; //隐藏
}
