mvc-System.Web.Mvc.ViewUserControl

Question

嘿... 如何在后操作中将提交按钮的 id 从 ViewUserControl 发送到控制器？当我有正常的视图时，我可以写这样的东西：

[HttpPost]
public  ActionResult KontaktIzabran(string myId)
{
    //some code 

}   

Now myId is alwasy null.... 这是我的用户控件

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<KontaktModel>" %>
<%@ OutputCache Duration="1200" VaryByParam="*" %>
<div id="sign-in-pop" class="popup">    
<div class="modal fat-form">
    <div class="clipper">
        <div class="left"></div>
        <div class="content">Sign In</div>
        <div class="right"></div>
    </div>                    
    <% Html.BeginForm("IzborKontaktaPopUp", "Kontakt"); %>
         <%: Html.ValidationSummary(true) %>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Naziv)%>
            <%: Html.ValidationMessageFor(model => model.Naziv) %>  
            <input type="submit" value="Traži" name="submitButton" id="submitButton" />
            <input type="submit" value="Dodaj novi" name="noviKontakt" />
        </div>
    <% Html.EndForm(); %>
</div>       
</div>   

Answer 1

[HttpPost]
public  ActionResult KontaktIzabran(string myId, string noviKontakt)
{
    if (!string.IsNullOrEmpty(noviKontakt))
    {
        // <input type="submit" value="Dodaj novi" name="noviKontakt" />
        // was used to submit the form
    }
    else
    {
        // <input type="submit" value="Traži" name="submitButton" id="submitButton" />
        // was used to submit the form
    }

    ...
}

嗯，看起来您没有名为“myId”的表单字段，因此提交无法将其发送回控制器。相反，它会发回一个包含当前值的 FormCollection：

<%: Html.TextBoxFor(model => model.Naziv)%>
<input type="submit" value="Traži" name="submitButton" id="submitButton" />
<input type="submit" value="Dodaj novi" name="noviKontakt" />
