In ASP.NET MVC 4 Razor, how do you get the value (text) of @Html.Label?

Question

I'm sorry I've tried searching but I didnt receive any information related to my problem.

My view:

<legend>COMFIRM</legend>
    @using (Ajax.BeginForm("AdminDeleteResult", "Admin",
                            new AjaxOptions { UpdateTargetId = "div" }))
    {
        <div id="div"></div>
        <h6>ARE YOU SURE WANT TO DELETE</h6>
        <ol>
            <li>
                @Html.Label("User ID:")
                @Html.Label("userid", Model.userid)
            </li>
            <li>
                @Html.Label("Username:")
                @Html.Label(Model.username)
            </li>
        </ol>
        <button>DELETE</button>
    }
</fieldset>

And my Controller:

[HttpPost]
public ActionResult AdminDeleteResult(FormCollection form)
{
     string userid = form["userid"].ToString(); //ERROR HERE
     ...
}

I've try to replace Label by @Html.TextBox("userid") and it works fine. But I want to use Label because I dont want people change it's value. Thank you for your help!

This is not the purpose of the Label you have to use an input. The purpose of the form is to collect data, and the data are kept in form elements.

If you don't want people to change the value (this can be discussed), you can make the input readonly or you can hide it.

Because your View make use of a Model you can use HtmlHelpers with lambda expression to create your form.

@using (Ajax.BeginForm("AdminDeleteResult", "Admin",
                        new AjaxOptions { UpdateTargetId = "div" }))
{
    <div id="div"></div>
    <h6>ARE YOU SURE WANT TO DELETE</h6>
    <ol>
        <li>
            @Html.Label(model => model.userid)
            @Html.TextBoxFor(model => model.userid, new { @readonly="readonly" })

            @* @Html.HiddenFor(model => model.userid) *@
        </li>
        <li>
            @Html.Label(model => model.username)
            @Html.TextBoxFor(model => model.username, new { @readonly="readonly" }) 
        </li>
    </ol>
    <button>DELETE</button>
}

As @man-nemati mentioned, it's better to use the model in your action

[HttpPost]
public ActionResult AdminDeleteResult(UserModel user)
{
   string userid =user.userid; // userid is storred in user
   // ...
}
