Html.EditorFor-如何根据post参数使用

Question

My ActionResult looks like this:

public ActionResult Index(string engineer, string contactName, 
                          string company,  string searchKeyword)
{

It then returns a view based on a few LINQ queries running underneath, which use the passed in parameters (engiener, contactName etc) to determine the returned model.

I am generating a form in the view which acts as a form to post values to the controller as to filter the results. At the moment it looks like this - the code works fine and the search boxes work but this seems like bad practice and I can't add a class in to Html.Editor:

<div class="form-group">
        <div class="editor-label">
            @Html.Label("Contact Name")
        </div>
        <div class="editor-field">
            @Html.Editor("contactName")
        </div>
    </div>
    <div class="form-group">
        <div class="editor-label">
            @Html.Label("Keyword Search")
        </div>
        <div class="editor-field">
            @Html.Editor("searchKeyword")
        </div>
    </div>

I want to be able to use an EditorFor as that seems best practice but as the parameters are not in the model I am not sure how to reference them in the first part of the statement?

@Html.EditorFor(model => what Do I put here!?)

You need to have those properties in the model, that's the point of this framework.

What you might not realize, though, is that the model you pass to the page (let's call it "view model") doesn't have to be the same as the one you store in the database (the "domain model"). The view model needs to have everything that the controller needs to pass from and to the view. The domain model needs to have everything that the controller needs to pass from and to the database.

While these may happen to be the same thing in trivial scenarios (like plain CRUD applications), if it doesn't work for you, don't hesitate to change them. Pass to the view a (new) kind of model that contains the parameters you need.
