Gridview的问题

Question

gridview

Answer 1

Scid='id' ? 改成
Scid='"+id+"' 你的ID都没传进去啊

Answer 2

对，这里有错。可以显示gridview,但里面没数据（数据库中检测是有的）

Answer 3

按照1楼说的你把string sqlstr = "SELECT * FROM shoppinglist WHERE Scid='id'";
改成： string sqlstr = "SELECT * FROM shoppinglist WHERE Scid='“+id+”'";
还是不好使么

Answer 4

对的string id = Session["username"].ToString();
            string sqlstr = "SELECT * FROM shoppinglist WHERE Scid='"+id+"'";
            string strCon = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
            SqlConnection Cn = new SqlConnection(strCon);
            Cn.Open();
            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, Cn);
            DataSet myds = new DataSet();
            
            myda.Fill(myds, "购物车");
            DataView view = myds.Tables["购物车"].DefaultView;
            GridView1.DataSource = view;
            GridView1.DataBind();
            Cn.Close();

Answer 5

前台是这样的
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" CellPadding="3" Font-Size="9pt" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Height="174px" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" Width="243px">
                        <FooterStyle BackColor="White" ForeColor="#ed1010" />
                        <Columns>
                            <asp:BoundField HeaderText="用户名" ReadOnly="True" />
                            <asp:BoundField HeaderText="商品名称" />
                            <asp:BoundField HeaderText="购买数量" />
                            <asp:BoundField HeaderText="下单时间" />
                        </Columns>
                        <RowStyle ForeColor="#000066" />
                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                        <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                        <HeaderStyle BackColor="#ed1010" Font-Bold="True" ForeColor="White" />
        </asp:GridView>

Answer 6

懂了，前台<asp:BoundField   HeaderText="用户名" ReadOnly="True" />中少DataField="Scid"
