Question

My form is not returning a null model.

I am viewing the details of a specific model on a Details page and then, if a user presses the SubmitPost button, the view should return the model.

View

@model MyApp.Models.MyModel
@using (Html.BeginForm("ApplyUsingDetails", "Controller", FormMethod.Post))
{
    <fieldset>
        <legend>Course</legend>
        <div class="display-label">MyModel ID</div>
        <div class="display-field">
            @Html.DisplayFor(model => model.CourseID)
        </div>

        <div class="display-label">Title</div>
        <div class="display-field">
            @Html.DisplayFor(model => model.Title)
        </div>
        etc. . .

        <p><input type="submit" value="SubmitPost" /></p>

        <more misc information for the view>
    </fieldset>
}

Action

[HttpPost]
public ActionResult ApplyUsingDetails(MyModel model)
{
// when I try to access model here it comes up null
}

To give some context: I am using this form to allow a student to view the details of a class and then apply to the class at the click of a button.

Any clue as to why my model would be null?

Answer 1

Based on the sample you provided, it doesn’t look like you are including any of MyModel‘s fields in the form. As a test, try including a hidden field or use @Html.HiddenFor(model => model.CourseID) and see if you have any values posted.
