gridview buttonfied 事件
那位朋友 可以帮我看看 我想通过添加一列按钮（buttonfield）实现批准用户注册，其中状态表示用户是否被批准，如果状态是0就是待批准的，如果状态是1，表明管理员已经批准了，现在，我不知如何编写buttonfield事件，来获取当前行的id,然后修改数据库，我看了很多的帖子，但是我都没有运行起来，希望大家帮帮我，谢谢了.......!我用的是：
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "a")//a 表示buttonfield的相关CommandName名称为a
{ datastring w = new datastring();//创建连接数据库字符串
using (SqlConnection coon = new SqlConnection(w.coonstring))
{
coon.Open();
........................ 我想问下这里如何实现获得修改当前选中行id(编号)，然后修改批准状态的
coon.Close();
}
ShowDB();//重新绑定数据库
}
}

protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)

/* SqlCommand sqlcom = new SqlCommand(sql, con);

GridView1.DataSource = ds;
GridView1.DataBind();
con.Close();*/
GridView1.EditIndex = -1;
Databind88(strsql88);
}
--------------------编程问答-------------------- 设置DataKeyNames属性
<asp:ButtonField ButtonType="Button" DataTextField="storage_code"
HeaderText="查看" Text="按钮" CommandName="save_btn"
DataTextFormatString="查看"/>
这个是必须的
