}
bind();

}

}
大概代码 但是 我用的三层架构 不知道 你看得懂不

string price = ((Label)GridView1.Rows[e.RowIndex].FindControl("lblprice")).Text;

lblprice是你前台页面绑定“单价”Label控件的id


<裂罩ItemTemplate>
'>



*******************************************************************
你的时间激活错了，你激活了RowDeleted删除后的事件，应该是RowDeleting事件
GridView的属性里有个DataKeyNames属性，将它绑定表里的主键列空租
然后激活
RowDeleting事件

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string id= GridView1.DataKeys[e.RowIndex].Value.ToString();
Response.Write ( id);
//把获取的id作为参数传给删除的方法

}

GridView.Rows[i].Cells[j].Text

获得i行j列的值

protected void GridView1_RowDeleting ( object sender, GridViewDeleteEventArgs e )
{
GridView grdProducts = sender as GridView;
string s = grdProducts.Rows [ e.RowIndex ].Cells [ 1 ].Text;

Response.Write ( s );
}
