aspnet代码

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
    AutoGenerateColumns="False" DataKeyNames="RefNo" DataSourceID="SqlDataSource1">
    <Columns>
        <asp:BoundField DataField="RefNo" HeaderText="RefNo" InsertVisible="False" 
            ReadOnly="True" SortExpression="RefNo" />
        <asp:TemplateField HeaderText="ProductID" SortExpression="ProductID">

    protected void btnSave_Click(object sender, EventArgs e)

            if (row.RowType == DataControlRowType.DataRow)

                cmd.CommandText = "SELECT SOID, RefNo, ProductID, Name, Price, Quantity, Amount FROM SODetails";

                GridView1.EditIndex = -1;
                GridView1.DataBind();

                con.Close();

            }
        }

    }

更改以下代码并从 BoundFields 获取值，因为 Value[0] 是 Ref 列值:

string Price = GridView1.DataKeys[row.RowIndex].Values[0].ToString();
string Quantity = GridView1.DataKeys[row.RowIndex].Values[0].ToString();
string Amount = GridView1.DataKeys[row.RowIndex].Values[0].ToString();
