Question

我有一个模特：

public class EmployeeDetails
{
    public int staffcode { get; set; }
    public string name { get; set; }
    public string designation { get; set; }
    public string department { get; set; }
}

单击“搜索”按钮，将从数据库中获取员工详细信息，并初始化模型属性。这些值也显示在视图上。

            dtEmpDetails = lib.RunSP("GetEmpDetails", lstEmpDetails);

            leaveBalanceViewModel.EmployeeDetail.staffcode = Convert.ToInt32(staffCode);
            leaveBalanceViewModel.EmployeeDetail.name = dtEmpDetails.Rows[0][0].ToString();
            leaveBalanceViewModel.EmployeeDetail.designation = dtEmpDetails.Rows[0][1].ToString();

还有另一个按钮保存。当我单击“保存”时，View中的文本框值会丢失，因为再次发生提交。

如何存储模型属性值并在回发期间保持可用状态？

最简单的方法是在服务器上存储会话中所需的所有内容，然后在提交后从该会话中填充所需内容。

如何在回发期间保留模型值？
