从使用模型到另一个模型的视图中，数据不会进入模型 [英] Data is not coming in model from the view using model into another model

问题描述

我正在尝试使用给定模型将数据和列表数据添加到单个视图中，数据列表工作正常，但在添加数据时，没有模型正常工作。



我有两个模型AddStudent和ListStudent，我通过合并到另一个模型AddStudentList在视图中使用它们。

I am trying to add data and list data into a single view using given models the data listing is working fine but while adding data no models is working.

I have two models AddStudent and ListStudent and I am using both of them in a view by merging into another model AddStudentList.

public class AddStudent
{
    public int EnrollmentNo { get; set; }
    public string StudentName { get; set; }
}

public class ListStudent
{
    public int EnrollmentNo { get; set; }
    public string StudentName { get; set; }
}

public class AddStudentList
{
    public AddStudent addStudentData {get; set;}
    public List<ListStudent> listStudentData {get; set;}
}

StudentController中的代码我正在使用：

The code in StudentController that i am using:

AddStudent addstudent = new AddStudent();
AddStudentList asl = new AddStudentList();
addStudent = asl.AddStudentData;
TryUpdateModel(addStudent);

这是我对这些模型的看法：

This is my view for these models:

@model AddStudentList

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h1>Add Student</h1>
<hr>
<div class="row row-centered">
    <div class="col-md-4 col-md-offset-3">


        @using (Html.BeginForm("AddStudent", "Student", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {
            <div class="form-group">
                @Html.TextBoxFor(m => m.AddStudentData.EnrollmentNo, new { @class = "form-control animated", placeholder = "Category Name", tabindex = 1 })
                @Html.ValidationMessageFor(m => m.AddStudentData.EnrollmentNo, null, new { @class = "error-class animated", @Style = "color:red;" })
            </div>
            <div class="form-group">
                @Html.DropDownListFor(m => m.AddStudentData.StudentName, new { @class = "form-control animated", tabindex = 2 })
                @Html.ValidationMessageFor(m => m.AddStudentData.StudentName, null, new { @class = "error-class animated", @Style = "color:red;" })
            </div>
            <div class="form-group">
                <div class="row">
                    <div class="col-sm-6 col-sm-offset-3">
                        <input type="submit" name="CategorySubmit" id="CategorySubmit" tabindex="6" class="form-control btn btn-login" value="Add Category">
                    </div>
                </div>
            </div>
        }
    </div>
</div>

    @{
        var grid = new WebGrid(Model.ListStudentData, canPage: true, rowsPerPage: 50);
    }
        @if (grid.Rows.Count > 0)
        {
            @grid.GetHtml(
                          htmlAttributes: new { @class = "table table-bordered table-responsive" },
                         columns:
                         grid.Columns(

                         grid.Column("EnrollmentNo", "Enrollment No."),

                         grid.Column("StudentName", "Student Name")))
}

我是什么尝试过：



我尝试过单独使用子模型和父模型，但数据仍未从视图传递到所需模型。

What I have tried:

I have tried using individually child and parent model but still data is not passing from view to the required model.

推荐答案

尝试使用模型的编辑器模板。

如果可能请将cshtml视图代码添加到您的问题中。

请点击以下链接

谢谢

Try using the editor template for the model.
If possible please add the cshtml view code onto your question.

问题在于控制器从模型中获取数据，这里是我使用过的代码并且它有效。我只是使用父模型AddStudentList并使用AddStudentList.AddStudent将值传递给数据库，它工作正常。



上一个代码：

The problem is in controller to get data from the model and here is the code which I have used and it worked. I just use the parent model AddStudentList and pass the values to the database using AddStudentList.AddStudent and it worked fine.

Previous Code:

AddStudent addstudent = new AddStudent();
AddStudentList asl = new AddStudentList();
addStudent = asl.AddStudentData;
TryUpdateModel(addStudent);

替换为此代码：

Replaced with this code:

AddStudentList asl = new AddStudentList();
TryUpdateModel(asl);
