请教！
private Order order;
protected void Page_Load(object sender, EventArgs e)
{
FaceControl(false);
}
// Open
protected void lkbOpen_Click(object sender, EventArgs e)
{
string errMsg = string.Empty;
order = Order.GetOrderCodeByOrderCode( "07061500001 ");
// 给界面赋值
txtOrderCode.Text = order.OrderCode.ToString();
txtOrderDate.Text = order.OrderDate.ToString();
txtQuantity.Text = order.Quantity.ToString();
txtStyleCode.Text = order.StyleCode.ToString();
txtRemark.Text = order.Remark.ToString();
}
protected void lkbSave_Click(object sender, EventArgs e)
{
try
{
order.OrderCode = txtOrderCode.Text;
order.OrderDate = txtOrderDate.Text;
order.Quantity = int.Parse(txtQuantity.Text);
order.StyleCode = txtStyleCode.Text;
order.Remark = txtRemark.Text;
order.Save();
CleanTextBox();
}
catch (Exception ex)
{
throw ex;
}
}
为什么不能保存啊！实力化order 应该在什么时候？ 我是先打开一条记录，将其保存在类中变量，然后修改，保存
[解决办法]
order.Save();
--------------------
Order的方法Save里是不是有问题便得保存失败?
