如何在视图元素中获取模型值 [英] how to get model values in view elements

问题描述

我的控制器是： -



[HttpPost]

公共ActionResult注册（StudentsModel mod，FormCollection frm）

{

StudentsModel model1 = new StudentsModel（）;

dbStudentsInfoEntities obj = new dbStudentsInfoEntities（）;

tbl_StudentRegistration tbl = new tbl_StudentRegistration （）;

string seach = Convert.ToString（frm [myHiddenText]）;

if（seach ==Save）

{

tbl.rollNumber = mod.RollNumber;

tbl.Name = mod.StudentsName;

tbl.City = mod.City;

tbl.Address = mod.Address;

obj.tbl_StudentRegistration.AddObject（tbl）;

obj.SaveChanges（）;

var data =来自obj.tbl_StudentRegistration中的n

selec tn;

ViewBag.Collection = data;



}

else if（seach ==Search ）

{



var rno = mod.RollNumber;

var data1 =来自obj.tbl_StudentRegistration中的n

其中n.rollNumber == rno

选择n;



foreach（数据1中的var d）

{

model1.RollNumber = d.rollNumber;

model1.StudentsName = d.Name;

model1。 City = d.City;

model1.Address = d.Address;



}



}



返回查看（注册，模型1）;

}

我的模特是：

My Controller is :--

[HttpPost]
public ActionResult Registration(StudentsModel mod,FormCollection frm)
{
StudentsModel model1 = new StudentsModel();
dbStudentsInfoEntities obj=new dbStudentsInfoEntities();
tbl_StudentRegistration tbl = new tbl_StudentRegistration();
string seach = Convert.ToString(frm["myHiddenText"]);
if (seach == "Save")
{
tbl.rollNumber = mod.RollNumber;
tbl.Name = mod.StudentsName;
tbl.City = mod.City;
tbl.Address = mod.Address;
obj.tbl_StudentRegistration.AddObject(tbl);
obj.SaveChanges();
var data = from n in obj.tbl_StudentRegistration
select n;
ViewBag.Collection = data;

}
else if (seach == "Search")
{

var rno=mod.RollNumber;
var data1 = from n in obj.tbl_StudentRegistration
where n.rollNumber==rno
select n;

foreach (var d in data1)
{
model1.RollNumber = d.rollNumber;
model1.StudentsName = d.Name;
model1.City = d.City;
model1.Address = d.Address;

}

}

return View("Registration", model1);
}
My model is :

public class StudentsModel
    {
        public int RollNumber { get; set; }
        public string StudentsName { get; set; }
        public string City { get; set; }
        public string Address { get; set; }
}

我的观点是： -

@using（Html.BeginForm（））{

@ Html.ValidationSummary（true）





StudentsModel

My View is:-
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)


StudentsModel

@ Html.LabelFor（a => a.RollNumber）

@Html.LabelFor(a => a.RollNumber)

@ Html.EditorFor（a => a.RollNumber，（@ Model.RollNumber））

@Html。 ValidationMessageFor（a => a.RollNumber）

@Html.EditorFor(a => a.RollNumber,(@Model.RollNumber))
@Html.ValidationMessageFor(a => a.RollNumber)

< input type =submitvalue =搜索id =搜索/> ;

<input type="submit" value="Search" id="Search"/>

@ Html.LabelFor（a => a.StudentsName）

@Html.LabelFor(a => a.StudentsName)

@ Html.EditorFor（a => a.StudentsName，（@ Model.StudentsName））

@ Html.ValidationMessageFor（a => a.StudentsName）

@Html.EditorFor(a => a.StudentsName, (@Model.StudentsName))
@Html.ValidationMessageFor(a => a.StudentsName)

< br $> b $ b

@ Html.LabelFor（a => a.City）

@Html.LabelFor(a => a.City)

@ Html.EditorFor（a => ; a.City，@ Model.City）

@ Html.ValidationMessageFor（a => a.City）

@Html.EditorFor(a => a.City,@Model.City)
@Html.ValidationMessageFor(a => a.City)

@ Html.LabelFor（a => a.Address）

@Html.LabelFor(a => a.Address)

@ Html.EditorFor（a => a.Address，@ Model.Address）

@ Html.ValidationMessageFor（a => a.Address）

@Html.EditorFor(a => a.Address,@Model.Address)
@Html.ValidationMessageFor(a => a.Address)

< input type =submitvalue =Saveid =SAVE/>

<input type="submit" value="Save" id="SAVE" />

< input type =hiddenname =myHiddenTextid =myHiddenText/>

<input type="hidden" name="myHiddenText" id="myHiddenText" />

i希望在MVC3中显示搜索模型数据
感谢提前

推荐答案

你可以这样做

you can do like this

foreach (var item in Model.StudentList)
{

 @Html.EditorFor(model=> item.RollNumber)
 @Html.EditorFor(model=> item.StudentsName )
 @Html.EditorFor(model=> item.City )
 @Html.EditorFor(model=> item.Address )

}

你必须强制输入模型才能从模型中获取值。

例如

@model ApplicationName.models.StudentsModel

You have to make model strongly typed in order to get values from model.
e.g.
@model ApplicationName.models.StudentsModel
