Question

我有一个视图，它在页面的左侧显示一个单选按钮列表，它还在页面右侧加载一个部分视图，该视图包含在弹出窗口中显示报告之前要选择的各种过滤器。

问题在于名为＆＃39; ReportName＆＃39;按下提交按钮时返回Null值，而不是返回所选Radiobutton的字符串值其他属性，如Branchcode，PeriodFrom，PeriodTo正确返回。

如果选择了radiobutton，我该怎么做才能获得正确的字符串值，例如AppointmentSummary，SplcodeRegSummary或SplcodeReg。

提前感谢您的帮助。

MODEL：

public class ReportModel
{
    [Required(ErrorMessage = "Please select a Report!")]
    public string ReportName { get; set; }
}

public class ReportFilters :ReportModel         //inherited 
{
    [Required(ErrorMessage="Please select Branch name!")]
    public int BranchCode { get; set; }

    [Required(ErrorMessage = "Please specify 'Period from' date!")]
    [DataType(DataType.Date)]
    public DateTime PeriodFrom { get; set; }

    [Required(ErrorMessage = "Please specify 'Period to' date!")]
    [DataType(DataType.Date)]
    public DateTime PeriodTo { get; set; }
}

控制器：

public ActionResult MIS1()
{
    ViewBag.Branch = (from c in BranchList().AsEnumerable()
                      orderby c["BranchName"]
                      select new { BranchCode = c["BranchCode"], BranchName = c["BranchName"] }).ToList();

    return PartialView();
}


public ActionResult MISPopup(ReportFilters rf)
{
    if (ModelState.IsValid)
    {
        return View(rf);
    }
    return View();
}

您的单选按钮组不在<form>标记内，因此在提交表单时不会发送其值。您需要将单选按钮移动到表单内部（在部分中）并删除属性ReportName的隐藏输入。

如果无法做到这一点，你可以考虑处理单选按钮的click()事件，因为使用javascript / jquery来更新表单中的隐藏输入

模型的继承属性始终返回空值
